Genom ett flertal forsok har det visat sig att aska, namligen vanlig vedaska frAn forbrAnning av gran, tall och lovtrAd av olika slag, och som enkelt erhAlles frAn brasor i t.ex. spisar, utgor naturens egen katalysator for omvandling och/eller Andring av olika amnens egenskaper pA biokemisk vAg. Med ytterligare hjalp av elektrolys, liknande effekt som erhAlles frAn Askan i naturen i det fria, kan man nu med hjalp av denna sagda katalysator Astadkomma en separation av oonskade ingredienser i t.ex. fOrorenat vatten. Forsaken visar klart att askan ar en forutsAttning for att kunna genomfOra fOrfarandet med onskat resultat, d.v.s. rening av den aktuella vAtskan. Utan aska sker ingen separation av ingAende delar av vAtskan under en rimlig tidsperiod utan i stAllet sker 2 det pa naturens eget satt over en Fang tidsperiod genom klarning och sedimentering. Through several experiments, it has been shown that ash, namely ordinary wood ash from the combustion of spruce, pine and firewood of various kinds, and which is easily obtained from fires in e.g. stoves, constitute nature's own catalyst for the transformation and / or change of the properties of various substances on a biochemical path. With the further help of electrolysis, a similar effect obtained from Ash in nature in the open air, it is now possible with the aid of this said catalyst to achieve a separation of undesirable ingredients in e.g. Contaminated water. The experiment clearly shows that the ash is a prerequisite for being able to carry out the procedure with the desired result, i.e. purification of the liquid in question. Without ash, no separation of constituent parts of the liquid takes place over a reasonable period of time, but instead it takes place in nature's own way over a period of time through clarification and sedimentation.
Aven annan slags aska an traaska kan nyttjas, exempelvis aska fran brunkol och/eller stenkol. Other types of ash other than ash can be used, for example ash from lignite and / or hard coal.
Genom motstandsmatning har aven konstate- rats att rent vatten (drickbart) har ett betydligt hogre motstand an fororenat vatten pa grund av olika salters och faroreningars inverkan. Det har ¥ visat sig att motstandet andras pa varierande satt genom innehallets paver- kan. Gasbubblor vid katoden och som tyder pa syrgas, har kunnat iakttagas. Vid anoden har kunnat konstateras bildande av vita tradar (skagg) och ett finmaskigt nat vilket kan tyda pa bildandet av aminosyror, proteiner eller liknande. Through resistance feeding, it has also been found that clean water (drinkable) has a significantly higher resistance to polluted water due to the effect of various salts and hazardous pollutants. It has been shown that the resistance of others in various ways through the influence of the content. Gas bubbles at the cathode and indicating oxygen have been observed. At the anode it has been possible to ascertain the formation of white threads (skag) and a fine-meshed net, which may indicate the formation of amino acids, proteins or the like.
Forsok har aven gjorts med elektroder av olika material i viss utstrackning dar elektroder av jamn visat sig vara bast. Vid forsok med elektroder av typen massingslaglod kunde konstateras att gran argliknande del bildades vid anoden som en del i den flytande kakan. vid forsok med avloppsvatten fran en tre- kammarbrunns 2:a kammare med elektroder av jam n i elektrolys kunde direkt konstateras att vatskan svartnade. Troligen bildades jarnoxid i nagon reaktion i samband med elektrolysen. Vatskan klarnade efter viss tid samt att en flytande kaka hade bildats av olika ingredienser i vatskan. Denna flytande kaka sedimenterar sedan under en langre tidsperiod i olika steg. Mellan den flytande kakan samt lite rester pa batten klarnade vatskan ganska snart. Experiments have also been made with electrodes of different materials to a certain extent where electrodes of even have been shown to be solid. In experiments with electrodes of the massing solder type, it could be found that spruce-like part was formed at the anode as a part of the liquid cake. In experiments with wastewater from the 2nd chamber of a three-chamber well with electrodes of iron n in electrolysis, it could be directly established that the liquid turned black. Iron oxide was probably formed in some reaction in connection with the electrolysis. The liquid cleared after a certain time and that a liquid cake had been formed from various ingredients in the liquid. This liquid cake then settles over a long period of time in different steps. Between the liquid cake and some leftovers on the boat, the liquid cleared up pretty quickly.
For forsaken har anvants 12 volt likstram samt vanlig vedaska fran mestadels gran och lavtrad som tillsatts samtidigt med kopplande av stremkallan. Behallare far forsaken har varit sterre glasburkar far att mini- 3 mera ovidkommande amnen samt far att kunna se och iakttaga eventuella forandringar. For the trial, a 12 volt direct current and ordinary wood ash from mostly spruce and lichen have been used, which has been added at the same time as connecting the strip cold. Container father forsaken has been larger glass jars father to minimize 3 irrelevant subjects and father to be able to see and observe any changes.
UtifrAn observation i forsok enligt ovanstaende, med forsok till beskrivning, har senare utveck- lats en biokemisk reaktor grundad pa observationer av repeterbara forsok avsedd f8r undersokning av vatskan mellan den flytande kakan och det sedimenterade materialet pA botten. Based on observations in experiments as above, with experiments for description, a biochemical reactor has later been developed based on observations of repeatable experiments intended for examining the liquid between the liquid cake and the sedimented material at the bottom.
Vid en forsta korning i denna reaktor anvAndes dricksvatten, dels for rengoring, dels far prov. Vatskan svartnade som ovan samt klarnade ganska snart. Den flytande kakan var mycket obetydlig (drickbart vatten). Den avtappade vatskan i behAllaren blev kristallklar samt att ett visst brunt sediment har bildats. Efter senare forsok kanske man kan frAga sig om detta var den i vattnet losta fosforn samt eventuella rester av jam. During a first run in this reactor, drinking water was used, partly for cleaning and partly for testing. The liquid turned black as above and cleared quite soon. The liquid cake was very insignificant (drinkable water). The drained liquid in the container became crystal clear and a certain brown sediment had formed. After later attempts, one may wonder if this was the phosphorus released in the water and any remnants of jam.
NAsta forsok innebar avloppsvatten frAn andra kammaren i en avloppsbrunn. Vatskan svartnade pa samma satt som tidigare forsok med aska. Under detta for- sok anvandes mindre mAngd aska varvid processen forlangdes i tid raknat. PA morgonen hade vatskan klarnat och kunde tappas upp i en starre glasburk for iakttagelser efter processen. Etter nAgra timmar kunde iakttagas en pAgAende process, med flockning i vatskan. FArgen bOrjade Andras till grant. Efter nagra timmar var vatskan morkgron. Tre dagar efter upptappningen i glasburken hade vatskan klarnat helt samt att ett brungult sediment hade bildats. Tiden maste narmare kontrolleras mellan upptappning och fArdig fallning, eftersom overraskningen stallde till det. The next experiment involved wastewater from the second chamber in a sewage well. The liquid turned black in the same way as previous experiments with ash. During this experiment, a smaller amount of ash was used, whereby the process was required in time. By morning, the liquid had cleared and could be poured into a rigid glass jar for observations after the process. After a few hours, an ongoing process could be observed, with flocculation in the liquid. The color began for others. After a few hours, the water was dark green. Three days after bottling in the glass jar, the liquid had completely cleared and a brownish-yellow sediment had formed. The time must be more closely controlled between bottling and finished falling, because the surprise came about.
Vid senare litteraturstudier tyder fenomenet pa en omvandling av fosfor i vatskan, fosforylering i en milj8 med jarnoxid vilket skulle ge den grana fArgen. Med ovanstAende observationer som grund, menar jag att med hjalp 4 av aska som katalysator i elektrolytisk process kunna avlagsna f6rorenande amnen samt fanning av fosfor och fosforforeningar fran min biokemiska reaktor. Forsaken har skapat majligheten att pavisa reningsverkens paverkan i miljon (recipient) genom studier fran utgaende (renat avloppsvatten) samt dess paverkan av det pavaxta materialet vid anoden som visat sig vara mycket kansligt for exempelvis jarnsulfat. Detta resulterade omgaende i ett svartnande och hopskrumpet nat liknande bottendOd som man kan iakttaga i havet utanfOr kommunala reningsverk. In later literature studies, the phenomenon indicates a conversion of phosphorus in the liquid, phosphorylation in an environment 8 with iron oxide, which would give the green color. Based on the above observations, I mean that with the help of ash as a catalyst in the electrolytic process I can remove pollutants and the formation of phosphorus and phosphorus compounds from my biochemical reactor. The research has created the opportunity to demonstrate the impact of the treatment plants in millions (recipient) through studies from outgoing (purified wastewater) and its impact on the grown material at the anode which proved to be very sensitive to, for example, ferrous sulphate. This immediately resulted in a blackening and shrinking night similar to the bottom that can be observed in the sea outside municipal treatment plants.
Majligheter finnes att genom skumning avlagsna den flytande kakan med fOroreningar frail vatska. Ytterligare mOjligheter skapas att kunna ta tram olika fraktioner fran den flytande kakan genom att en biokemisk reaktion pagar med en fanning av olika lager under en langre Lid, med barjan underst pa kakan. Den tredje majligheten är enligt ovan beskrivning att ta vatskan direkt efter klarning fran den svarta fargen samt lata den sjalvgaende processen i denna vatska utfora omvandling samt fanning av fosfor och fosforfOreningar. Det fallda materialet kan sedan avlagsnas fran processen. Bottensediment fran oaktiva delar i askan mm kan mekaniskt avlagsnas frail processen. There are possibilities to remove the liquid cake by foaming with contaminants frail liquid. Additional possibilities are created to be able to take different fractions from the liquid cake by a biochemical reaction with a formation of different layers during a longer Lid, with the bar at the bottom of the cake. The third possibility is, as described above, to take the liquid immediately after clarification from the black color and to let the obvious process in this liquid carry out conversion and formation of phosphorus and phosphorus compounds. The fallen material can then be removed from the process. Bottom sediment from inactive parts of the ash etc. can be mechanically removed from the process.
Den svarta fargen fran bOrjan av processen samt den klarnande delen kan utnyttjas fOr reglering av processens genomforande. Den klara vatskans farg efter reaktorn samt den grOna fargen vid processen, klarnande efter fosforomvandlingen och f&llningen kan utnyttjas vid regleringen av processen. The black color from the beginning of the process and the clarifying part can be used to regulate the execution of the process. The color of the clear liquid after the reactor and the green color of the process, clarifying after the phosphorus conversion and precipitation can be used in the regulation of the process.
Enligt uppfinningen innefattar ett fOrfa- rande fOr rening och avskiljning av fOrorenande amnen 1 fran fOrorenat vatten 2 att man later blanda i traaska eller annan aska 3 i det fororenade vattnet 2 samt later igangsatta elektrolysbehandling av den sagda blandningen 4. Darigenom sker separation och biokemiskt avskiljning av icke Onskvarda fororeningar. Darvid nyttjar man traaska eller annan aska 3 erhallen fran en spis eller nagon annan lamplig eldstad eller fOrbranningskalla. According to the invention, a process for purifying and separating the polluting substances 1 from polluted water 2 comprises mixing in ashes or other ash 3 in the polluted water 2 and initiating electrolysis treatment of the said mixture 4. Thereby separation and biochemical separation takes place. of non-adverse contaminants. In doing so, they use traaska or other ash 3 obtained from a stove or some other suitable fireplace or incinerator.
For elektrolysbehandlingen nyttjar man elektroder 5, 6 av jam, varigenom blandningen 4 forst svartnar i det nyttjade karl 7, for att efter viss tid klarna. Darvid har en flytande kaka 8 bildats ovan vattnet 2 av innehallande fororeningar och fosforforeningar 1 i det fororenade vattnet 2. Efter viss tid later man avtappa renat vatten 9 fran karlet 7 efter det att den sagda kakan 8 med fororeningar 1 dari sedimenterat och att rester 11 darav bildats pa botten 10 av det karl 7 som nyttjas vid det sagda forfarandet. Alternativt kan man genom ej visad men allmant kand skumning lata avlagsna kakan 8 innan sedimentering av densamma sker for senare behandling. Detta kan ske i ett enda skede eller successivt allteftersom kakan 8 hailer pa att bildas alternativt kan filtre- ring utnyttjas nar kakan sedimenterat/sedimenterar fOr erhallande av olika delar i innehallet. For the electrolysis treatment, electrodes 5, 6 of jam are used, whereby the mixture 4 first turns black in the used vessel 7, in order to clear after a certain time. Thereby a liquid cake 8 has been formed above the water 2 of contaminants and phosphorus compounds 1 in the contaminated water 2. After a certain time, purified water 9 is drained from the vessel 7 after the said cake 8 with contaminants 1 has settled therein and residues 11 of which formed on the bottom 10 of the man 7 used in the said process. Alternatively, by not showing but generally known foaming, the cake 8 can be allowed to be deposited before sedimentation of the same takes place for later treatment. This can take place in a single stage or successively as the cake 8 tends to form, alternatively filtration can be used when the cake has settled / sediments to obtain different parts of the content.
Lampligt ar att lata rena avloppsvatten som mottages efter grovavskiljning i sa kallade trekammar- brunnar, i reningsverk eller i andra liknande anlagg- ningar. Darvid tager man avloppsvatten fran en sagda trekammarbrunns tredje kammare fOr rening. Efter viss tid fran iblandning av traaska eller annan aska 3 och elektrolys av blandningen 4 klarnar avloppsvattnet efter bildande av en flytande kaka 8 av fororeningar och fosfor- foreningar 1 och sedimentering av densamma eller Ater-faring till tidigare steg, liknande aktiv slamprocess for senare slamsugning sa att avtappning av renat avloppsvatten 9 sker skilt fran kvarvarande rester 11 av forore- 6 ningar pa botten 10 av brunnen eller annat nyttjat karl i vilket sagda rening Astadkommes. Eftersom vatskan 2 i karlet 7 andrar farg kan man lata styra f6rfarandet efter de farger som bildas under forfarandets gang. It is appropriate to allow clean wastewater that is received after coarse separation in so-called three-chamber wells, in treatment plants or in other similar facilities. In this case, wastewater is taken from the third chamber of a said three-chamber well for treatment. After some time from mixing of ash or other ash 3 and electrolysis of the mixture 4, the wastewater clears after formation of a liquid cake 8 of impurities and phosphorus compounds 1 and sedimentation thereof or re-experience to earlier steps, similar active sludge process for later sludge suction so that the treatment of treated wastewater 9 takes place separately from the remaining residues 11 of contaminants 6 at the bottom 10 of the well or other used man in which said treatment is achieved. Since the liquid 2 in the vessel 7 changes color, the process can be controlled according to the colors formed during the process.
Avlagsning av den flytande kakan 8 pa vatskan 2 i karlet 7 sker genom foljande atgarder: att man later skumma av den flytande kakan 8, eller att man later ta fram olika fraktioner fran den flytande kakan 8 genom att en biokemisk reaktion pagar med en fallning av olika lager av fororeningar och fosforfareningar under viss tid med borjan underst pa den flytande kakan, eller att man later ta ut vatskan 2 direkt efter klar- ning fran markfargad vatska och sedan later en sjalvgaende process i sagda vatska 2 utfora omvandling samt utfallning av fosfor och fosforforeningar varefter det utfallda materialet avlagsnas och bottensediment 11 fran den joke aktiva delen av askan 3 och ovrigt innehAll mekaniskt avlagsnas fran karlet 7. Deposition of the liquid cake 8 on the liquid 2 in the vessel 7 takes place by the following procedures: that the liquid cake 8 is allowed to foam, or that different fractions are produced from the liquid cake 8 by a biochemical reaction with a precipitation of different layers of impurities and phosphorus compounds for a certain time with the beginning at the bottom of the liquid cake, or that the liquid 2 is allowed to be taken out immediately after clarification from soil-colored liquid and then an independent process in said liquid 2 is carried out to convert and precipitate phosphorus and phosphorus compounds after which the precipitated material is deposited and bottom sediment 11 from the joke active part of the ash 3 and other contents are mechanically deposited from the vessel 7.
