UGSI PolyBlend^® Dry Polymer Feed System offers a unique two-stage method of initial high-shear mixing followed by low-shear mixing. The mechanical activation of the dry polymer ensures polymer optimization and lowers operating costs. An innovative stainless steel “hollow wing” mixing impeller in the mix/hold tank reduces polymer consumption by providing proper energy at low speed through impeller size and recirculation to prevent agglomerations while minimizing polymer fracture. With minimal maintenance and a small footprint, the PolyBlend^® DP is fully automatic and easy-to-operate.

Fairfield-Suisun Sewer District, California Case Study

• Rated capacity 23.7 MGD
• Goal:  using less polymer results in fewer deliveries, less trucks and congestion on the road, and fewer greenhouse gas emissions.
• Trial: PolyBlend^® DP800 Dry Polymer Preparation Demo Trailer at two applications within the plant: the screw press and the gravity belt thickener.
• Results:
  • Screw Press: polymer use reduced from 255 to 200 pounds per day, a 22% savings.
  • GBT: polymer use reduced from 29 to 20 pounds per day, a 31% savings.
