Preparation and Feeding Information

PWT 3920 is a dry polymer that must be pre-diluted in water before use. One method for dilution is adding the polymer into the vortex of a mixed tank at a concentration between 0.1 - 0.5% polymer by weight and then mixing at slow speed (300 rpm maximum). A much better method is to use a dry polymer make down system. A number of commercially available systems will produce excellent results. Polymer solutions should be aged for 30-60 minutes prior to use for best results. Solution shelf life is 8-16 hours.
