1. Fremgangsmåde til konditionering af septisk spildevand for at forhindre dannelse af hydrogensulphid og forhindre efterfølgende præcipitation af FeS, kendetegnet ved, at fremgangsmåden omfatter trinnet med samtidig tilsætning til det det septiske spildevand af en vandig opløsning af jemsalte, udvalgt fra gruppen bestående af FeC^, FcC13, FeClSC>4, FeSC>4 og blandinger deraf, som omsættes med en anionisk polymer, udvalgt fra gruppen bestående af calciumlignosulphonat og natriumlignosulphonat, der interagerer med dannet FeS til en kolloidal sol, der er stabil over for præcipitation.
2. Fremgangsmåde ifølge krav 1, kendetegnet ved, at en vandig blanding af både jemsalte og lignosulphonat i masseforholdet mellem jemsalt og anionisk polymer i intervallet på 1:0,5 til 1:1,5 beregnet som vandfrie stoffer, tilsættes to det septiske spildevand.
3. Fremgangsmåde ifølge krav 2, kendetegnet ved, at blandingen fremstilles af vandige opløsninger af jemsalte med en koncentration på 20 % til 40 % og af vandige opløsninger af anionisk polymer med en koncentration på 10 % til 30 %.
4. Fremgangsmåde ifølge et hvilket som helst af de foregående krav 1 til 3, kendetegnet ved, at j emsaltopløsning og anionisk polymeropløsning kan tilsættes som en blanding af begge opløsninger.
5. Fremgangsmåde ifølge et hvilket som helst af de foregående krav 1 til 4, kendetegnet ved, at j emsaltopløsning og anionisk polymeropløsning kan tilsættes samtidigt som separate opløsninger.
6. Fremgangsmåde ifølge et hvilket som helst af de foregående krav 1 til 5, kendetegnet ved, at jemsaltene er udvalgt fra gruppen bestående af FeCF og FcCF, og den anioniske polymer er udvalgt fra gruppen bestående af calciumlignosulphonat og natriumlignosulphonat.
7. Fremgangsmåde ifølge et hvilket som helst af de foregående krav 1 til 5, kendetegnet ved, at jemsaltene er udvalgt fra gruppen bestående af FeClS04 og FeS04, og den anioniske polymer er udvalgt fra gruppen bestående af natriumlignosulphonat.
