Abstract

1519692 Purifying waste water COMMISSARIAT A L'ENERGIE ATOMIQUE 24 Feb 1976 [24 Feb 1975] 07251/76 Heading C1C In a process for purifying waste water containing organic substances wherein the water is percolated through a substance which adsorbs the organic substances, the saturated adsorbent is regenerated by passing through the adsorbent a mineral solution containing oligo-elements. The adsorbent substance is preferably activated charcoal. The mineral solution containing oligo-elements is preferably a solution containing compounds of nitrogen, phosphorus, potassium and mineral salts, a preferred solution contains sodium acid phosphate, potassium acid phosphate, magnesium sulphate, calcium chloride, ammonium nitrate and ferric chloride.
