Poultry & Slaughter
Fat trap + DAF + Anaerobic + Aerobic N
Slaughter and processing effluents are rich in blood, fat, protein and solids, driving very high COD, FOG and nitrogen. KEMISTA recovers solids and fat, digests organics to biogas, then removes nitrogen biologically before disinfection.

Why this configuration
Solids & fat recovery protects biology and yields rendering by-product value.
High-rate anaerobic digestion of strong organic load with energy recovery.
Nitrification / denitrification meets ammonia and total-nitrogen consents.
Pathogen control through final disinfection for safe reuse.
Your sector not listed, or a stream that defies the categories?
KEMISTA characterises the stream and engineers a bespoke train — that is what bench and pilot testing are for.
