Polymer Preparation Module - Model 515 Module


Acrison’s advanced Model 515 Polymer Preparation Module cuts water and wastewater treatment costs through the accurate metering, positive dispersion, and complete wetting of dry and liquid polymers. The Model 515 Preparation System automatically and efficiently prepares a homogeneous and precise solution from either dry or liquid polymers at low to moderate capacities.

For wetting dry polymers, the Model 515 System utilizes a very effective cyclone wetting chamber design, incorporating an initial swirling water vortex, enhanced by a series of impinging water jets. 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 W105 Dissimilar Speed, Double Concentric Auger Volumetric Feeder – ensures positive, accurate and reliable feed of dry polymer into the wetting chamber
  • Easy Operation – provides automatic switch-over 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 tank and aging tank shipped on a separate skid when furnished with system)
  • All Steel Construction – provides long-term durability with minimal maintenance requirements
  • Mixing/Aging tanks – can be configured to allow maximum flexibility, especially for installation in areas having space limitations


  • All product contact parts are 304 stainless steel, except for the Cyclone Wetting Chamber, metering auger, and transfer pump which are 316 stainless steel
  • An Acrison Model W105 Series Dissimilar Speed, Double Concentric Auger Volumetric Feeder for metering dry polymers; powered by a 1/2 horsepower, totally enclosed variable speed AC or DC gearmotor. The feeder is completely dust-tight and sealed to shield the hygroscopic polymer from the atmosphere
  • Operated by an Allen-Bradley Micrologix PLC with an 8-inch color touch screen operator interface, and includes Ethernet capability as standard
  • Mixing and aging tanks include ultrasonic level transmitters for non-contact measurement, changeable set-points, and continuous level display.


  • Various materials of construction
  • Integral feeder supply hoppers of various capacities
  • Bag loading hopper
  • Dust collector/bag dump station
  • Various AC and DC variable speed motor controllers and control modes
  • Liquid polymer metering/blending package with Acrison’s exclusive Dispersion-Injector
  • Polymer solution metering pump
  • Various size and configuration mixing/aging tanks to suit application parameters
