Preparation and Feeding Information
  • WWT 123 is a single component emulsion polymer that must be pre-diluted in water before use. In most cases, this product should not be applied neat. One method for dilution is adding the neat polymer into the vortex of a mixed tank at a concentration between 0.25 - 1.0% polymer (0.5% is optimum)by weight.
  • The polymer can also be injected through a number of commercially available systems that provide in-line mechanical mixing. Polymer solutions should be aged for 30-60 minutes prior to use for best results. Solution shelf life is 8-16 hours.

Materials of Construction
  • Cross-linked polyethylene, fiberglass, stainless steel or lined steel are the preferred materials of construction for bulk tanks. Avoid natural rubber and Buna-N gaskets as these materials swell when placed in contact with neat polymer.
  • Unlined mild steel, black iron, galvanized steel, copper or brass are not recommended in any part of the feed system. Stainless steel, Viton or Teflon are the best choices for pump heads. For feed lines, polyethylene, PVC or reinforced Tygon tubing is recommended.
Storage, Stability and Handling Information
  • Suggested in-plant storage life is one year in unopened drums. For best results, store at 50 - 80°F. Bulk tanks should be mixed by periodically recirculating the contents bottom to top. Bulk tanks can also be fitted with an agitator type mixer that reaches the bottom 2 feet of the tank.
  • Do not allow emulsion polymers to freeze. Should freezing occur, allow the product to thaw thoroughly in a heated area and mix well before attempting to use it.
  • For spills of WWT 123, sprinkle salt, vermiculite or equivalent absorbent over the spill area and sweep the material into approved chemical disposal containers. Do not spray water onto a spill because the resulting gel is very difficult to clean up.
