The plant operators were concerned about the coagulant usage, and believed a removable full diameter sparger would diffuse the coagulant better than the side mounted port they were currently using.A corporation stop removable injector, 30 inches in length was installed through a threaded blind flange attached to welded port. The improved chemical diffusion effectively increased the coagulant contact time.


Coagulant usage decreased by 30%
