Process characterised in that the "alpechin" is subjected to a controlled flocculation process by means of an aqueous solution of surface-active, cationic nitrogen fat derivatives, in a weight proportion of "alpechin"/fatty derivatives of 0.2 to 0.7%, all this inside a vessel with a mechanical agitator and metering pump for the flocculent products, filtration, settling (decantation) or centrifugation being used to obtain a non-polluting liquid phase and a solid phase composed of an organo- mineral residue. This process applies especially to the treatment of "alpechin" resulting from the manufacture of olive oil, in order to eliminate the biodegradable organic material from the "alpechin".
