Titel: Slamudskiller.Title: Sludge separator.
Opfindelsen angår en slamudskiller med mindst en indløbstilslutning til tilledning af væske til slamudskilleren og mindst to udløbstilslutninger til udledning af væske fra 5 slamudskilleren.The invention relates to a sludge separator with at least one inlet connection for supplying liquid to the sludge separator and at least two outlet connections for discharge of liquid from the sludge separator.
I tyndt bebyggede områder håndteres ejendommenes afløbsvand i almindelighed ejendomsvis, eftersom der i tyndt bebyggede områder typisk ikke findes adgang til kommunal teknik til håndtering af afløbsvand. Til rensning af afløbsvand anvendes 10 ejendomsvis et rensningsanlæg i jorden, hvor rensningen sker i to trin. I det første trin forbehandles afløbsvandet i en slamudskiller, i hvilken faste partikler udskilles fra afløbsvandet. I det andet trin absorberes afløbsvandet i jordbunden eller filtreres og opsamles i dræningsgrøfter, hvorfra det rene vand ledes via en opsamlingsbrønd, f.eks. til en åben grøft. De faste partikler, som er samlet i slamudskille-15 ren, leveres af og til f.eks. til det kommunale rensningsanlæg.In sparsely built-up areas, the wastewater of the properties is generally handled property-wise, since in sparsely built-up areas there is typically no access to municipal technology for managing wastewater. To purify wastewater, a property purification plant is used in the soil where the purification takes place in two steps. In the first step, the effluent is pretreated in a sludge separator in which solid particles are separated from the effluent. In the second step, the wastewater is absorbed into the soil or filtered and collected in drainage ditches from which the pure water is fed via a collection well, e.g. to an open ditch. The solid particles collected in the sludge separator are sometimes delivered e.g. to the municipal wastewater treatment plant.
I et rensningsanlæg i jorden ifølge absorberingsprincippet udledes afløbsvandet fra ejendommen via et jordudløb til en slamudskiller, som er installeret under jordoverfladen med undtagelse af en tømningsåbning. Udløbsvandet, som er renset 20 for faste partikler, udledes gennem et rør fra slamudskilleren til en fordelingsbrønd, som med undtagelse af tømningsåbningen er placeret under jordoverfladen. Fordelingsbrønden har i den nedre del to eller flere udløbstilslutninger, hvorfra udløbsvandet udledes til absorberingsrør, som er beliggende under jordoverfladen i et rensningsfelt. Eftersom det funktionsmæssigt, ved rensning i jorden, er fordelag-25 tigt, at vandmængderne, som udledes til de forskellige absorberingsrør, er lige store, er separate strømningsregulatorer bestående af en rørformet tilslutningsdel og en reguleringsplade installeret i fordelingsbrønden i forbindelse med udløbstilslutningerne til regulering af den til absorberingsrørene strømmende vandmængde. Et rensningsanlæg i jorden ifølge filtreringsprincippet er i strukturen hovedsagelig li-30 gesom et rensningsanlæg i jorden ifølge absorberingsprincippet, men i rensningsfeltet er opsamlingsdræningsgrøfter anbragt under absorberingsrørene. Opsamlingsdræningsgrøfterne opsamler det rensede vand og fører det til en opsam- 2 DK 176795 B1 lingsbrønd. Det rensede vand fra opsamlingsbrønden udledes via et udløbsrør til en åben grøft eller et andet passende sted i terrænet.In a soil purification plant according to the absorption principle, the effluent water is discharged from the property via a soil outlet to a sludge separator installed below the soil surface with the exception of a discharge opening. The effluent, which is purified of solid particles, is discharged through a pipe from the sludge separator to a distribution well, which, with the exception of the discharge opening, is located below the soil surface. In the lower part, the distribution well has two or more outlet connections, from which the outlet water is discharged to absorbent pipes located below the soil surface in a purification field. Since it is functionally advantageous, when purified in the soil, that the quantities of water discharged to the different absorption pipes are equal, separate flow regulators consisting of a tubular connection part and a control plate are installed in the distribution well in connection with the outlet connections for regulating the the amount of water flowing to the absorbent pipes. A soil purification plant according to the filtration principle is in the structure mainly similar to a soil purification plant according to the absorption principle, but in the purification field, collection drainage ditches are located below the absorption pipes. The collection drainage trenches collect the purified water and lead it to a collection well. The purified water from the collection well is discharged via an outlet pipe to an open ditch or other suitable location in the terrain.
Problemet med nuværende rensningsanlæg i jorden er det store antal komponen-5 ter, som indgår i et rensningsanlæg, hvilket forøger udgifterne til rensningsanlægget ved anskaffelsen af komponenter og medfører meget arbejde ved installering af systemet.The problem with current wastewater treatment plants is the large number of components included in a wastewater treatment plant, which increases the cost of the wastewater treatment plant when purchasing components and entails a lot of work in installing the system.
Hensigten med denne opfindelse er at tilvejebringe en slamudskiller af en ny type.The object of this invention is to provide a new type of sludge separator.

Slamudskilleren ifølge opfindelsen kendetegnes af, at slamudskilleren har mindst to udløbstilslutninger til udledning af væske fra slamudskilleren, og at strømningsregulatorer er anbragt i forbindelse med udløbstilslutningerne til regulering af den fra udløbstilslutningerne strømmende vandmængde, og at strømningsregulatorer-15 ne er anbragt i forbindelse med udløbstilslutningerne i disses øvre del og omfatter en stamme og en i stammen beliggende strømningsåbning.The sludge separator according to the invention is characterized in that the sludge separator has at least two outlet connections for discharging liquid from the sludge separator and that flow regulators are arranged in connection with the outlet connections for controlling the flow of water from the outlet connections and the flow regulators connected to the outlet connections. their upper part and comprises a stem and a flow opening located in the stem.
Opfindelsens væsentlige ide er, at slamudskilleren har mindst en indløbstilslutning for tilledning af væske til slamudskilleren og mindst to udløbstilslutninger til udled-20 ning af væske fra slamudskilleren, og at strømningsregulatorer er anbragt i forbindelse med udløbstilslutningerne for regulering af den fra udløbstilslutningerne strømmende vand-mængde. Ifølge en fordelagtig udførelsesform for opfindelsen er udløbstilslutningen formet som en T-forgrening. Ifølge en anden fordelagtig udførelsesform for opfindelsen er strømningsregulatoren anbragt i forbindelse med 25 udløbstilslutningen på slamudskillerens inderside. Ifølge en tredje fordelagtig udførelsesform for opfindelsen har det som strømningsregulator anvendte rør mindst en neden for strømningsåbningen beliggende rille, som er rettet mod indersiden af strømningsregulatorens stamme.The essential idea of the invention is that the sludge separator has at least one inlet connection for supplying liquid to the sludge separator and at least two outlet connections for the discharge of liquid from the sludge separator, and that flow regulators are arranged in connection with the outlet connections for regulating the flow from the outlet terminals. . According to an advantageous embodiment of the invention, the outlet connection is shaped as a T-branch. According to another advantageous embodiment of the invention, the flow regulator is arranged in connection with the outlet connection on the inside of the sludge separator. According to a third advantageous embodiment of the invention, the pipe used as a flow regulator has at least one groove located below the flow opening, which is directed to the inside of the flow regulator stem.

Fordelen med opfindelsen er, at når strømningsregulatorerne er anbragt i forbindelse med slamudskilleren, kan fordelingsbrønden undlades i rensningsanlæg i jorden, hvorved anskaffelsesudgifterne til systemet og mængden af installeringsarbejde formindskes. Når strømningsregulatorerne er anbragt på indersi-5 den af slamudskilleren, er anvendelsen af strømningsregulatorer også efter installering af slamudskilleren let. Den i strukturen rørformede strømningsregulator, som placeres inden i udløbsåbningen, er let at anvende, og der behøver ikke at reserveres plads for den inden i beholderen. Takket være udtag placeret under strømningsåbningen i den rørformede strømningsregulator er det let at 10 kontrollere vandoverfladens niveau.The advantage of the invention is that when the flow controllers are arranged in connection with the sludge separator, the distribution well can be omitted in soil purification plants, thereby reducing the cost of the system and the amount of installation work. When the flow regulators are located on the inside of the mud separator, the use of flow regulators is also easy after installing the mud separator. The tubular flow regulator, which is placed inside the outlet opening, is easy to use and no space is required for it inside the container. Thanks to outlets located below the flow opening in the tubular flow regulator, it is easy to control the level of the water surface.

30 I fig. 1 er slamudskilleren 1 ifølge opfindelsen vist skematisk set fra siden og delvist i tværsnit og i fig. 2 set forfra og delvist i tværsnit. Slamudskilleren 1 har kamre 3 og 4, som er adskilt af en mellemvæg 2. Slamudskilleren 1 har i den øvre del på kammerets 3 side en indløbstilslutning 5, til hvilken jordafløbet fra DK 176795 B1 4 ejendommen tilsluttes. For tydelighedsskyld er mellemvæggen 2 og indløbstilslutningen 5 ikke vist i fig. 2. Endvidere har slamudskilleren 1 en tømningsåbning 6 via hvilken slamudskilleren 1 kan tømmes. Tømningsåbningen 6 dækkes med slamudskillerens 1 låg, som for tydelighedens skyld ikke er vist i figurerne 5 1 og 2. Efter hver tømning fyldes slamudskillerens 1 kamre 3 og 4 med vand.In FIG. 1, the sludge separator 1 according to the invention is shown schematically from the side and partly in cross section and in FIG. 2 is a front view and partly in cross section. The sludge separator 1 has chambers 3 and 4 which are separated by a partition wall 2. The sludge separator 1 has in the upper part of the side of the chamber 3 an inlet connection 5 to which the ground drain from DK 176795 B1 4 is connected to the property. For the sake of clarity, the intermediate wall 2 and the inlet connection 5 are not shown in FIG. 2. Furthermore, the sludge separator 1 has a discharge opening 6 through which the sludge separator 1 can be emptied. The discharge opening 6 is covered with the lid of the sludge separator 1 which, for the sake of clarity, is not shown in Figures 5 1 and 2. After each emptying, the chambers 3 and 4 of the sludge separator 1 are filled with water.
Den øvre del af mellemvæggen 2 har et eller flere huller, gennem hvilke udløbsvandet, som kommer fra indløbsåbningen 5 til kammeret 3, strømmer fra kammer 3 til kammer 4. Udløbsvandet er beregnet til at strømme så langsomt som muligt fra kammer 3 til kammer 4, således at de største partikler når at 10 synke ned til kammerets 3 bund i et slamrum. I kammeret 4 fortsætter rensningen af udløbsvandet for faste partikler, dvs. de faste partikler, som er overført fra kammer 3 til kammer 4, synker til bunden af kammeret 4 i et slamrum. Kammeret 4 har to udløbsåbninger 7 og 7' i form af T-forgreninger, gennem hvilke det for faste partikler rensede udløbsvand strømmer ud af slamudskille-15 ren 1. Udløbstilslutningerne 7 og T er i lodret retning dimensioneret således, at de i deres nedre ende hele tiden befinder sig under vandoverfladen i slamudskilleren 1 og i deres øverste ende over vandoverfladen. Således strømmer udløbsvandet kun ind i udløbstilslutningerne 7 og 7’ i deres nedre ende. Udløbstilslutningerne 7 og 7’ har i det væsentlige vandret beliggende rørdele 8 og 8', 20 som er indrettet til at hælde nedad, så vandet strømmer fra udløbstilslutningerne 7 og 7' ud af slamudskilleren 1. Eftersom udløbsvandet, som strømmer bort fra slamudskilleren 1, udledes neden under vandoverfladen, befordres de på overfladen flydende faste partikler ikke via udløbstilslutningerne 7 og 7' ud fra slamudskilleren 1. Inden i udløbstilslutningerne 7 og 7' er anbragt strømnings-25 regulatorer 9 og 9', som er vist nærmere i fig. 3 og 4, og ved hjælp af hvilke mængden af udløbsvand, som via udløbstilslutningerne 7 og 7' strømmer ud fra slamudskilleren 1, kan reguleres således, at den er lige stor i begge udløbstilslutningerne 7 og 7'. Eftersom strømningsregulatorerne 9 og 9' er anbragt i forbindelse med slamudskilleren 1, kan fordelingsrørene, gennem hvilke ud-30 løbsvandet strømmer til absorberingsrørene i rensningsfeltet i rensningsanlægget i jorden anbringes direkte i slamudskillerens 1 udløbstilslutninger 7 og T.The upper part of the intermediate wall 2 has one or more holes through which the outlet water coming from the inlet opening 5 to the chamber 3 flows from chamber 3 to chamber 4. The outlet water is intended to flow as slowly as possible from chamber 3 to chamber 4. so that the largest particles reach sink to the bottom of chamber 3 in a sludge chamber. In chamber 4, the purification of the effluent for solid particles continues, i.e. the solid particles transferred from chamber 3 to chamber 4 sink to the bottom of chamber 4 in a sludge chamber. The chamber 4 has two outlet openings 7 and 7 'in the form of T-branches through which the outlet water purified for solid particles flows out of the sludge separator 1. The outlet connections 7 and T are dimensioned in a vertical direction so that they at their lower end constantly located below the water surface in the sludge separator 1 and at its upper end above the water surface. Thus, the outlet water only flows into the outlet terminals 7 and 7 'at their lower end. The outlet terminals 7 and 7 'have substantially horizontally located pipe portions 8 and 8', 20 arranged to pour downwardly so that the water flows from the outlet terminals 7 and 7 'out of the sludge separator 1. Since the outlet water flowing away from the sludge separator 1, discharged below the water surface, the solid particles floating on the surface are not conveyed via the outlet connections 7 and 7 'from the sludge separator 1. Inside the outlet connections 7 and 7' are flow regulators 9 and 9 ', which are shown in more detail in FIG. 3 and 4, and by means of which the amount of outlet water flowing out of the sludge separator 1 via the outlet connections 7 and 7 'can be adjusted to be equal in both outlet connections 7 and 7'. Since the flow regulators 9 and 9 'are arranged in connection with the sludge separator 1, the distribution pipes through which the outlet water flows to the absorption pipes in the purification field of the soil purification plant can be placed directly in the outlet connections 7 and T. of the sludge separator 1.
Derved kan fordelingsbrønden, i hvilken strømningsregulatorerne tidligere har været placeret, udelades, hvorved anskaffelsesudgifterne til rensningssystemet DK 176795 B1 5 formindskes. Også det arbejde, som kræves til installeringen, nedsættes, eftersom man ikke behøver at lave en skakt til en fordelingsbrønd. Takket være strømningsregulatorerne 9 og 9' i forbindelse med slamudskilleren 1, kan vandmængderne, som strømmer via udløbstilslutningerne 7 og 7' til absorbe-5 ringsrørene endvidere reguleres, så de er lige store, hvorved rensningsfeltet kan belastes jævnt, hvilket er en forudsætning for lang brugstid for rensningsanlæg i jorden og høj rensningseffekt.In this way, the distribution well in which the flow controllers have previously been placed can be omitted, thereby reducing the acquisition cost of the purification system DK 176795 B1 5. Also, the work required for installation is reduced, since you do not need to make a shaft for a distribution well. Furthermore, thanks to the flow regulators 9 and 9 'in connection with the sludge separator 1, the quantities of water flowing through the outlet connections 7 and 7' to the absorption pipes can be regulated so that they can be evenly loaded, which is a prerequisite for a long load. service life of soil treatment plants and high purification effect.
I fig. 3 er en strømningsregulator 9, som anvendes i en slamudskiller ifølge op-10 findelsen skematisk vist set forfra og i fig. 4 skematisk set fra siden. Strømningsregulatoren 9 er i figurerne 3 og 4 anbragt inden i udløbstilslutningen 7. Strømningsregulatoren 9 er et rør, hvis stamme 10 har en strømningsåbning 11.In FIG. 3 is a flow controller 9 used in a sludge separator according to the invention schematically shown from the front and in FIG. 4 is a schematic side view. The flow regulator 9 is located in Figures 3 and 4 within the outlet connection 7. The flow regulator 9 is a pipe whose stem 10 has a flow opening 11.
Den i fig. 3 viste strømningsåbning 11 er dråbeformet, men strømningsåbningen II kan udformes på mange forskellige måder. Strømningsregulatoren 9 har i 15 den øvre ende en flange 12, hvis ydre diameter er større end den ydre diameter af strømningsregulatorens 9 stamme 10. Flangens 12 ydre diameter er også større end udløbstilslutningens 7 øvre ende på indersiden, således at strømningsåbningen 11 og rørdelen 8 havner på samme sted som den på fig. 5 viste måde, når strømningsregulatoren 9 er i sin nederst mulige stilling, dvs. sin 20 grundstilling. Afstanden mellem strømningsåbningens 11 nedre kant og flangen 12 dimensioneres således, at strømningsåbningens 11 nedre kant er på den i fig. 5 viste måde i det væsentlige i plan med rørdelens 8 nedre kant, når strømningsregulatoren 9 er i sin lavest mulige stilling. Ved at flytte strømningsregulatoren 9 opad, flyttes den ved rørdelen 8 beliggende strømningsåbnings 11 ned-25 re kant opad, hvorved den til rørdelen 8 strømmende vandmængde aftager.The FIG. 3, the flow opening 11 can be formed in many different ways. The flow regulator 9 has at its upper end a flange 12, the outer diameter of which is greater than the outer diameter of the stem of the flow regulator 9. The outer diameter of the flange 12 is also larger than the upper end of the outlet connection 7, so that the flow opening 11 and the pipe part 8 at the same location as that of FIG. 5 when the flow controller 9 is in its lowest possible position, i. its 20 basic position. The distance between the lower edge of the flow opening 11 and the flange 12 is dimensioned such that the lower edge of the flow opening 11 is on the one shown in FIG. 5 is substantially in plane with the lower edge of the pipe member 8 when the flow regulator 9 is in its lowest possible position. By moving the flow regulator 9 upwards, the lower edge of the flow opening 11 located at the pipe part 8 is moved upwards, whereby the amount of water flowing to the pipe part 8 decreases.
Den ydre diameter af strømningsregulatorens 9 stamme 10 dimensioneres i forhold til udløbstilslutningens 7 indre diameter, så strømningsregulatoren 9 på grund af friktionskraften mellem den ydre overflade af strømningsregulatorens 9 stamme 10 og udløbstilslutningens 7 indre overflade ikke af sig selv flyttes i for-30 hold til rørdelen, men flytning af strømningsregulatoren 9 lykkes let uden værktøj, hvorved det er enkelt at regulere den til rørdelen strømmende vandmængde via tømningsåbningen 6.The outer diameter of the stem 10 of the flow regulator 9 is dimensioned with respect to the inner diameter of the outlet connection 7, so that the flow regulator 9, due to the frictional force between the outer surface of the stem 10 of the flow regulator 9 and the inner surface of the outlet connection 7, is not moved by itself relative to the pipe part. but the movement of the flow regulator 9 succeeds easily without tools, whereby it is easy to regulate the amount of water flowing to the pipe via the discharge opening 6.

Fra fabrikken stilles strømningsregulatorerne 9 og 9' i grundstilling på den i fig.From the factory, the flow controllers 9 and 9 'are set in the basic position in the position shown in FIG.
5 viste måde, således at strømningsåbningens 11 nedre kant er i plan med de nedre kanter af rørdelene 8 og 8'. Når slamudskilleren 1 tages i brug, løftes den ene strømningsregulator således at vandmængden, som strømmer til begge 5 rørdelene 8 og 8', er lige stor. Derved hindrer slamudskillerens 1 noget skrå position i skakten ikke reguleringen af den fra udløbstilslutningerne 7 og 7' strømmende vandmængde, således at den bliver lige stor. Man stræber dog efter at placere slamudskilleren 1 i skakten i så lige en stilling som mulig. Kontrol og efterregulering af strømningsregulatorernes 9 og 9' stilling er let at udføre i forbin-10 delse med tømning af slamudskilleren 1, f.eks. en gang om året.5 so that the lower edge of the flow opening 11 is flush with the lower edges of the pipe portions 8 and 8 '. When the sludge separator 1 is put into operation, one of the flow regulators is lifted so that the amount of water flowing to both pipes 8 and 8 'is equal. Thereby, the somewhat oblique position of the mud separator 1 in the shaft does not impede the regulation of the amount of water flowing from the outlet connections 7 and 7 'to be equal. However, one strives to place the sludge separator 1 in the shaft in as close a position as possible. Checking and post-regulation of the position of the flow regulators 9 and 9 'is easy to perform in connection with emptying the sludge separator 1, e.g. once a year.
En eller flere riller 13 kan på den i fig. 3 viste måde udformes i strømningsregulatorens 9 stamme 10 neden under strømningsåbningen 11, hvilke riller retter sig mod stammens 10 indre side. Rillerne 13 er nærmere vist i fig. 6, som ske-15 matisk viser en strømningsregulator 9, set oppefra og i tværsnit langs den i fig.One or more grooves 13 may, in the manner shown in FIG. 3 is formed in the stem 10 of the flow regulator 9 below the flow opening 11, which grooves is directed to the inner side of the stem 10. The grooves 13 are further shown in FIG. 6, which schematically shows a flow regulator 9, viewed from above and in cross-section along that of FIG.
3 viste snitlinje A-A. Rillerne 13 kan også udformes ved at forøge materialet på stammens 10 inderside, hvorved stammen 10 er en enhed fra ydersiden med undtagelse af strømningsåbningen 11. Takket være rillerne 13 er det enkelt og let oppefra at kontrollere vandoverfladens niveau i udløbstilslutningerne 7 og 7' 20 samt regulere strømningsregulatorerne 9 og 9' til vandoverfladens niveau. Afvigende fra fig. 1 og 2 kan udløbstilslutningerne 7 og 7' også dimensioneres således, at de strækker sig gennem slamudskillerens 1 væg eller låg, hvorved strømningsregulatorerne 9 og 9' kan reguleres uden at åbne slamudskillerens 1 låg.3 shows line A-A. The grooves 13 can also be formed by increasing the material on the inside of the stem 10, whereby the stem 10 is a unit from the outside with the exception of the flow opening 11. Thanks to the grooves 13, it is simple and easy to control the level of the water surface in the outlet connections 7 and 7 '20 and regulating flow regulators 9 and 9 'to the level of the water surface. Different from FIG. 1 and 2, the outlet connections 7 and 7 'can also be dimensioned so that they extend through the wall or lid of the sludge separator 1, whereby the flow regulators 9 and 9' can be controlled without opening the lid of the sludge separator 1.
25 I stedet for en i figurerne 1-6 vist strømningsregulator 9 kan man i forbindelse med udløbstilslutningerne 7 og 7' anvende en strømningsregulator, som dannes på en i og for sig kendt måde af en rørformet tilslutningsdel og en reguleringsplade, som er forsynet med en strømningsåbning. En sådan strømningsregula-30 tor kan anbringes i forbindelse med rørdelene 8 og 8' enten på indersiden eller ydersiden af slamudskilleren 1. Når strømningsregulatorerne er placeret på ydersiden af slamudskilleren 1, er det meget besværligt at udføre reguleringsforanstaltninger efter installering af slamudskilleren 1, eftersom slamudskilleren DK 176795 B1 7 1 er placeret underjordoverfladen, således at i det væsentlige kun tømningsåbningen 6 befinder sig overjordoverfladen. Anvendelsen af en strømningsregulator, som dannes af en rørformet tilslutningsdel og en reguleringsplade, er sammenlignet med den rørformede strømningsregulator 9 meget besværligere selv, 5 når den er installeret på indersiden af slamudskilleren 1. Endvidere er den rørformede strømningsregulator 9 i sin struktur enklere, billigere at fremstille samt lettere at installere på plads.Instead of a flow regulator 9 shown in FIGS. 1-6, in connection with the outlet connections 7 and 7 ', a flow regulator formed in a manner known per se by a tubular connection member and a control plate provided with a flow regulator can be used. flow opening. Such a flow regulator may be arranged in conjunction with the pipe parts 8 and 8 'either on the inside or outside of the sludge separator 1. When the flow regulators are located on the outside of the sludge separator 1, it is very difficult to carry out control measures after installing the sludge separator 1, since the sludge separator DK 176795 B1 7 1 is located below the surface so that substantially only the discharge opening 6 is located above the surface. The use of a flow regulator formed by a tubular connection member and a regulating plate is much more difficult compared to the tubular flow regulator 9, when installed on the inside of the sludge separator 1. Furthermore, the tubular flow regulator 9 in its structure is simpler, cheaper to manufacture as well as easier to install in place.
Slamudskillerens udseende eller form kan variere på mange måder. Endvidere 10 kan slamudskilleren omfatte blot et kammer eller en slamudskiller kan med en mellemvæg deles i flere end to kamre. Slamudskilleren kan omfatte mere end en indløbstilslutning, hvorved udløbsvandet fra flere ejendomme eller fra flere rør fra samme ejendom kan udledes til samme slamudskiller. Endvidere kan slamudskilleren have flere end to udløbstilslutninger, hvorved flere absorbe-15 ringsrør kan placeres i rensningsfeltet. Strømningsregulatorerne 9 og 9' kan også udformes uden en flange 12 eller i stedet for en flange 12 kan anvendes en rille, som retter sig udad fra stammen 10 eller et andet tilsvarende spærreorgan. Strømningsregulatoren 9 kan også anvendes i forbindelse med en dræningsbrønd, gulvbrønd, en vandlås under et bassin samt med olie- og fedtudskillere.The appearance or shape of the sludge separator can vary in many ways. Further, the sludge separator may comprise only one chamber or a sludge separator can be divided into more than two chambers by a partition. The sludge separator may comprise more than one inlet connection, whereby the effluent from several properties or from several pipes from the same property can be discharged to the same sludge separator. Furthermore, the sludge separator may have more than two outlet connections, whereby several absorbent pipes may be placed in the purge field. The flow controllers 9 and 9 'can also be designed without a flange 12 or instead of a flange 12 a groove which extends outwardly from the stem 10 or another corresponding locking means can be used. The flow regulator 9 can also be used in conjunction with a drainage well, floor well, a water trap under a basin, and with oil and grease separators.
