FIELD: organic fertilizers. SUBSTANCE: in order to efficiently separate solid phase from liquid one, into fermented sludge 60-70 g/l of phospho-gypsum is added. Sludge is further separated into fractions using electric floatation with current density 50-60 mA/sq.cm. In this process, phospho-gypsum initiates coagulation of highly dispersed and colloid solid-phase particles providing floatation of the latter with electrolytic gas bubbles. Method may be used in production of fertilizers from waste. EFFECT: facilitated separation process. 2 dwg
