Customer Requirements

The purpose of the chemical treatment process is to bind and flocculate fats, oil, greases, and phosphates for removal with a filter press.  This customer has a very low phosphate discharge limit, and their process was producing variable results with regards to phosphate removal.  They required chemistry and a procedure that would make their process compliant with the low phosphate limitation.


MetaLube application specialists audited the process and found their procedure lacked the ability to read and react to normal variations in the incoming phosphate level.  Our team assisted the customer’s manufacturing engineers with the development of a procedure to check initial phosphate levels, and add calculated amounts of chemicals based on the phosphate content.  In addition to procedural modifications, we supplied the customer with MetaLube WT which is an extremely efficient anionic polymer flocculent.  A reduction in chemical costs associated with flocculent usage was achieved due to the effectiveness of MetaLube WT.  There have been no issues with exceeding their phosphate discharge limit in the two years since revising this process.
