Polymer Feed and Control

polymer feed Since its 1972 introduction, our PolyBlend® Series has become a world leader in automated polymer feed systems. Chemists will continue to refine existing polymers and develop new ones, just as they have for more than 35 years. Operators should demand a polymer feeder that can keep up with breakthroughs in polymer technology for years to come.


Today's PolyBlend® polymer feeders are a family of engineered systems embodying decades of reliable field performance and the latest in polymer activation technology. Experience has shown that polymers require a special combination of mixing and aging in order to achieve full activation. Consequently, the equipment used to prepare a polymer solution must have both flexibility and design features based on solid fundamentals in order to provide the ideal mixing environment. With precise control of dosing rate, dilution level, mixing time, and applied energy, PolyBlend® systems control the key polymer activation criteria of energy profile, aging and dilution to optimize polymer performance. PolyBlend® polymer activation technology has the heritage and incorporated science to ensure operators, engineers, and chemical suppliers that today's liquid and dry polymers will provide maximum performance and value.

PolyBlend® Products Application
PB Series A compact footprint of only 1 to 1.5 square feet depending on frame size. It is lighter than most polymer feeders, making it ideal for portable use or where intermittent use requires the system to be stored in one location and used in another. Available in a wide range of capacities up to 75 US gpm (280 l/min).
M-Lo Series Engineered for easy installation and maintenance and ready-to-install, the system provides consistent and accurate dosage and improves polymer efficiency. Its compact size and trouble-free installation are ideal for confined spaces and the open-frame design facilitates easy component access. Available in capacities from 0.4 to 2.5 US gph (1.5 to 9.5 lph).
M Series Combines proven motorized mixing technology with precise controls, a variety of pump offerings and an easy-to-service open-frame design. Then we add two unique options: variable speed mixing and automatic dosage control with constant solution strength. Available in a wide range of capacities up to 200 US gpm (760 l/min).
H Series We no longer offer a hydraulic mixing polymer feed system, however either our PolyBlend® M or PB series polymer mixers can offer you the reliability you trust to handle the mixing capacities that were offered in the PolyBlend® H series.
DP Series PolyBlend® DP systems have an unmatched reputation for reliability. The DP system typically reduces polymer consumption 25% or more while substantially improving polymer performance in terms of sludge dryness, solids capture, water clarity, drainage / retention, or any other measure. Available in a wide range of capacities up to 45 pounds/hour (20 kg/hour).
Accessories A multitude of accessories are available for your PolyBlend® systems, including dry polymer extension hoppers and bulk bag frameworks, tables, drum mixers, air dryers, and more.

Polymer Feed and Control Case Study: New Polymer Feed System Provides Efficient Polymer Activation for Less Capital Outlay, Smaller Footprint

The 1.5 million gallons per day (MGD) West Carrollton Wastewater Treatment came on-line in 1989 and today serves 12,000 area residents. The activated sludge facility produces an average of 200 wet tons/month of sludge that, following belt filter press dewatering, is spread on area farmland by a biosolids management company. Polymer is added to the sludge prior to belt press dewatering to aid in liquid-solid separation. Read more here.
