Challenge
Opportunity


A canned food company producing 62,000 m3/month effluent used polyaluminum chloride 18% as coagulant and anionic polymer as an auxiliary of flocculation. The treatment presented difficulties due to changes in pH caused by the performance of CIP procedures (Clean In Place).

Flox®-QT was tested in the laboratory with the aim of improving the quality of treated effluent, and decreasing the volume and improving the quality of the sludge. Good results were obtained leading to successful industrial-scale implementation of Flox®-QT and approval for permanent use. During the weekly periods of CIP procedures that major changes in pH (friday to sunday), Flox®-QT is replaced by Flox®-QTH with excellent results.

Since the consumption of anionic polymer emulsion was extremely high, a dry polymer preparer was installed reducing the cost of this reagent in approximately 70%.
