The treatment plant was failing to meet its COD discharge consent limitation, with sufficient chemical dosing and clarification installations to utilise, Jems was asked to determine why the plant could not effectively treat the effluent.
Having carried out extensive on-site testing and analysis to determine why the system was constantly failing, the operators are now recycling more bi-products and a large amount of money has been saved. As a result, the influence upon the ETP has been dramatically reduced allowing normal operations to resume.
In an effort to better prepare the effluent for treatment, some minor changes and installations were made to allow for smoother operation. Such as: Different grade mesh fitted to the basket strainers to allow more fluent operation, tanker replaced with a permanent primary settlement tank, balancing tank fitted with agitators.
Jems also provided the site operations team with further training in the use of the chemical dosing units and system as a whole, resulting in further improvements to the effluent quality.
