DAF + Anaerobic + Aerobic
Beverage, brewery and food-processing effluents carry high, readily-biodegradable organic loads with sugars, starch, FOG and solids. High-rate anaerobic digestion turns this into renewable biogas, with aerobic polishing and disinfection to reuse standard.

Why this configuration
Renewable energy — biogas recovery offsets a large share of site heat demand.
Compact high-rate biology handles strong, variable loads in a small footprint.
Odour control integrated across screening, EQ and sludge handling.
Reuse-ready polishing with filtration and UV disinfection.
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.
