Client

UK Turkey Abattoir serving UK supermarkets and the UK food service industry discharging effluent direct to watercourse.

Issues

Out of consent discharges in terms of Biological Oxygen Demand (BOD) and ammonia levels plus high costs of sludge disposal including significant tankering charges removing primary sludge from site. Existing treatment facility not functioning consistently.

Proposal

– Install parabolic screen to remove particles > 0.75mm

– Install pH correction and monitoring system to ensure effluent reaching the biological treatment plant would be at an optimum pH

– Install a Decanter Centrifuge using ferric chloride as a coagulant and cationic polymer as flocculant to dewater primary and secondary sludge

– Install new biological treatment plant
