Abstract

Ionic surfactants are removed from waste waters by e.g. - amts. of surfactants of opposite charge, and sufficient acid (pref. sulphuric) to set pH 1-3. Opt. floats of previous treatments may be used for adjustment of pH. The treated water is heated to 40-80 deg.C until fluid and float phases separate. The aq. phase is neutralised with hydrated lime to pH 8-11. Finally sulphuric acid is added to pH 6-7 and sludge formed is sepd..
