1. Förfarande för syreberikning av vattnet i sjöar eller lik-nande som är tillräckligt djupa för att vattnet under sommarperi-oden skall uppdelas i väsentligen tvä termiska skikt, ett övre, varmare skikt (epilimnion), och ett undre, kallare skikt (hypolimnion), varvid genom tillförsel av en blandning av syrehaltig gas och vatten en gaskudde upprätthälles i hypolimnion i ett klöckliknande hus (12, 21), i vilken gaskudde den i vattnet oupplösta gasen av-skiljes frän vattenströmmen och därifran avledes frän huset tili atmosfären utan störning av omgivande termiska skiktning medan den syreberikade vattenströmmen ledes ut i hypolimnion ur huset, kännetecknat därav, att säväl vattenströmmen som bil-dandet av vatten-luft-blandningen ästadkommes genom utsläpp av gas, företrädesvis luft, direkt i hypolimnion under upprätthällande av i och för sig känd kontinuerlig mammutpumpverkan i riktning rnot gaskudden i huset (12, 21).
2. Förfarande enligt patentkravet 1, kännetecknat därav, att huset med gaskudden hälles flytande pä djupet i sjön fixerat vid en bottenförankring (44).
3· Anordning för utförande av förfarandet enligt patentkrav 1 eller 2 för syreberikning av vattnet i sjöar eller liknande som är tillräckligt djupa för att vattnet under sommarperioden skall uppdelas i väsentligen tvä termiska skikt, ett övre, varmare skikt (epilimnion), och ett undre, kallare skikt (hypolimnion), varvid genom tillförsel av en blandning av syrehaltig gas och vatten en gaskudde upprätthälles i hypolimnion i ett klöckliknande hus (21), i vilken gaskudde den i vattnet oupplösta gasen avskiljes frän vattenströmmen och därifrän avledes frän huset tili atmosfären utan störning av omgivande termiska skiktning medan den syreberikade vattenströmmen ledes ut i hypolimnion ur huset, känneteck-n a d av att den innefattar en huvudsakligen vertikalt riktad upp-ät och nedät öppen blandingskanal (27) i huset (21) och ett i hypolimnion placerat gasmunstycke (28) vid kanalens (27) nedre ände
