High Capacity Packaged Polymer Processing System - Model 500

Model 500 Polymair® Dry/Liquid Polymer Preparation System


Acrison’s Model 500 Polymair Preparation Systems cut water and wastewater treatment costs through the accurate metering, positive dispersion, and complete wetting of dry and liquid polymers. The Model 500 Preparation System automatically and efficiently prepares a homogeneous and precise solution from either dry or liquid polymers at moderate to high capacities.

For wetting dry polymers, the Model 500 System utilizes a novel dry air atomizing system and Cyclone Wetting Chamber, especially effective when handling dry polymers possessing a very fine particle size.  Liquid polymers are metered into Acrison’s exclusive, highly efficient Dispersion Injector where they are mixed with water and then discharged into the system’s mixing tank.


  • An Acrison Model W-105 Dissimilar Speed, Double Concentric Auger Volumetric Feeder is used to meter dry polymer – ensures positive, accurate and reliable feed of dry polymer into the Cyclone Wetting Chamber
  • Easy Operation – provides automatic transfer from dry to liquid or liquid to dry operation without equipment modification
  • Skid-mounted System – completely assembled and mounted on a ‘skid’ type base (mixing/aging tank shipped separately when furnished with system)
  • All Steel Construction – provides long-term reliability with minimal maintenance requirements
  • Aging tank(s) – can be configured to allow maximum flexibility, especially for installation in areas having space limitations
