This is one component of a whey and milk processing plant:
"The design offered operational flexibility to achieve optimum performance for each stage of the process, and utilised an efficient biological approach to treating mostly soluble chemical oxygen demand (COD) in the Creamery effluent thus avoiding the use of additional chemicals, associated labour costs and increased chemical and sludge handling requirements. Typical Creamery waste feed and treated effluent qualities are depicted in Figure 1. The upgraded plant treats an average flow of 2000 m3/day at a COD loading that was 7000 kg/day during commissioning. Treated effluent has a biological oxygen demand of < 9 mg/l and total suspended solids of < 12
mg/l.
The existing ETP design included a two stage CAS process with high and low rate biological aeration tanks in series, each with separate settlement tanks. Clarified effluent was treated by a Lockertex screen prior to final discharge to the River Inny. Existing pre-treatment included a grease trap, a small divert tank and an aerated balance tank. The effluent flow was then treated in two anoxic tanks before entering the CAS plant. Waste activated sludge was dewatered using a belt press and then tankered away for off-site disposal."
