Imidlertid kommer også helse-skader i betrakt-ning da drikkevann også brukes til vaske-og badevann såvel som til fylling av akva-rier og til å sette fiskekasser under vann smell and taste that are in the foreground. However, health damage is also taken into account as drinking water is also used for washing and bathing as well as for filling aquariums and for putting fish boxes under water

På den annen side er virkningen av On the other hand, the impact of

ozon som steriliseringsmiddel ikke varig ozone as a sterilizing agent not permanent

forlangt en bakterisid ettervirkning ved demanded a bactericidal aftereffect by

mange anvendelsesområder for vann, særlig i svømmebad. Nettopp i disse er imidlertid de ovenfor nevnte ulemper på grunn av many areas of application for water, especially in swimming pools. Precisely in these, however, the above-mentioned disadvantages are due to

for stort klorinnhold i vannet særlig føl-bare, idet opphold i dette vann ikke bare too high a chlorine content in the water particularly noticeable, as staying in this water not only

og svømmeren er derfor ikke bare utsatt for and the swimmer is therefore not only exposed to

den ubehagelige sterke klorlukten, men the unpleasant strong smell of chlorine, but

også for helseskader ved innånding av denne sterkt klorholdige luft. also for health damage by inhaling this highly chlorine-containing air.

Den foreliggende oppfinnelse har til hensikt å utnytte fordelene såvel ved klor-som ved ozon-behandling av vann og vandige oppløsninger uten å ta med deres ulemper på kjøpet, og går ut på en frem-glangsmåtei til sterilisering av vann og vandige oppløsninger, karakterisert ved en kombinert behandling med ozon og klor eller klorholdige stoffer, f. eks. klorkalk. The present invention intends to utilize the advantages of both chlorine and ozone treatment of water and aqueous solutions without including their disadvantages in the purchase, and is based on an advanced method for sterilizing water and aqueous solutions, characterized by a combined treatment with ozone and chlorine or chlorine-containing substances, e.g. chlorinated lime.

Herved kan klorinnholdet i vannet, henholdsvis i den vandige oppløsning, av-passes slik at det er så lavt at det er tilstrekkelig for den bakteriside ettervirkning uten at det tilsynelatende volder de ubehagelige bivirkninger, hvorigjennom den grundige sterilisering skjer ved den foregående hovedprosess hvor en passende tilmålt ozontilsetning virker helt ut. In this way, the chlorine content in the water, or in the aqueous solution, can be adjusted so that it is so low that it is sufficient for the bactericidal aftereffect without apparently causing the unpleasant side effects, through which the thorough sterilization takes place in the preceding main process where a suitable measured ozone addition works perfectly.

Særlig betydning får fremgangsmåten i henhold til oppfinnelsen ved anvendelse til sterilisering av svømmebad fylt med havvann eller saltoppløsninger, hvorved steriliseringen mest hensiktsmessig skjer 1 tilberedningsprosessen ved omvelting av havvannet, henholdsvis saltoppløsningen, og det til steriliseringen benyttete klor blir tilvirket umiddelbart fra den vandige nat-riumkloridholdige oppløsning ved elektrolyse og brakt til å virke i' sin aktive tilstand. Det er kjent at klor er mest virk-somt i denne tilstand. Det samme gjelder for det klor som er bundet i klorholdige stoffer og som blir aktivt ved oppløsning i vannet. Som følge av den større virksom-het av dette klor kan dets konsentrasjon holdes desto mindre, noe som er særlig gunstig da klorets ulemper med hensyn til lukt, smak og sunnhet fremkommer i enda større grad i saltoppløsningen enn i fersk-vann. Enda større betydning får derfor steriliseringsmetoden i henhold til oppfinnelsen ved behandling av saltoppløsninger, da det med et minimalt klorinnhold kan oppnås en fullverdig sterilisering og en varig bakterisid virkning, når det for største-delen blir brukt ozon og for en mindre del Mor til klorholdige stoffer. Gjennom anvendelse av den for tilberedning av salt-oppløsninger utviklede fremgangsmåte på vann og vandige oppløsninger av andre slag, kan det også ved disse unngås de varige bivirkninger, som opptrer når man bruker bare klor eller klorholdige stoffer eller bare ozon etter hittil gjeldende meto-der. The method according to the invention becomes particularly important when used for sterilizing swimming pools filled with seawater or salt solutions, whereby the sterilization most appropriately takes place in the preparation process by stirring the seawater, respectively the salt solution, and the chlorine used for the sterilization is produced immediately from the aqueous sodium chloride-containing dissolution by electrolysis and brought to work in its active state. It is known that chlorine is most effective in this condition. The same applies to the chlorine that is bound in chlorine-containing substances and that becomes active when dissolved in the water. As a result of the greater activity of this chlorine, its concentration can be kept all the less, which is particularly beneficial as chlorine's disadvantages with respect to smell, taste and health appear to an even greater extent in the salt solution than in fresh water. The sterilization method according to the invention therefore becomes even more important when treating salt solutions, as with a minimal chlorine content full sterilization and a lasting bactericidal effect can be achieved, when ozone is used for the most part and Mother for chlorine-containing substances for a smaller part . By applying the method developed for the preparation of salt solutions to water and aqueous solutions of other kinds, the lasting side effects that occur when using only chlorine or chlorine-containing substances or only ozone according to the methods currently in force can also be avoided with these .

Som følge av den sterke nedsetting av klorinnholdet i det behandlete vann lar det seg gjøre, blant annet i svømmehaller, å unngå den ubehagelige klorlukt som opp-står ved den hittil gjeldende fremgangsmåte til sterilisering ved hjelp av klor. Videre er det mulig å sterilisere havvann, henholdsvis oppløsninger, som skal brukes til å drikkes eller til kurer, uten at det får en ubehagelig klorlukt. As a result of the strong reduction of the chlorine content in the treated water, it is possible, for example in swimming pools, to avoid the unpleasant smell of chlorine that arises from the hitherto current method of sterilization using chlorine. Furthermore, it is possible to sterilize seawater, respectively solutions, which are to be used for drinking or for cures, without it getting an unpleasant chlorine smell.
