Biochemica brings plant back to life through phosphate removal

A plant suffering from ongoing performance issues regarding phosphate removal from its effluent stream approached Biochemica to help rectify the situation. The consent to discharge for phosphate was 15mg/l, which the plant had achieved just once over the prior 12 months.

Biochemica quickly performed test work to optimise chemical dose rates and illustrate the expected phosphate removals that could be realised under the new treatment regime.

Some important process changes were also implemented and the effluent plant recommissioned. After recommissioning, with influent phosphate levels averaging 400mg/l, a consistent discharge of 0.6mg/l phosphate was achieved.
