METHOD OF TENSIDES REMOVAL FROM WASTE WATERS

The method of removing surfactants is being solved from wastewater, which is carried out by means of ultrafiltration. To the waste water with the contents anionic or non-ionic surfactants, in particular ethoxylated alkylphenols, alkylpolyethylene glycol ethers and alkylbenzene sulfonates are added the amount of heavy oil with a specific weight less than 1 in order to bind all in the waste water contained surfactants heavy the oil remained part of it, whereupon it was redundant the oil will set aside and the remaining waste water is passed through an ultrafiltration membrane.
