FIELD: process engineering.
SUBSTANCE: process can be used for preparation of said liquid wastes for irrigation and fertilising of agricultural lands. Effluents of pig-breeding farms are processed with the solution of silica-alumina coagulant based on nepheline in amount of 10-35 mg/dm3 by Al2O3. Note here that pH varies from 6.5 to 7.5. After treatment of the mix in exposed hydraulic cyclone, it is separated to transparent liquid fraction and precipitate, i.e. organic mineral fertilisers.
EFFECT: expanded range of processing of suspensions, simplified process, lower costs, complete decontamination of liquid and solid phases.
