The Leader in Polymer Activation and Blending – Offering the Best in Hydraulic and Mechanical Activation

polymer feed UGSI Chemical Feed is proud to offer the most comprehensive line of both hydraulic and mechanical polymer activation methods. 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.

UGSI Chemical Feed includes the Polybend® mechanical polymer feeders with the Dynablend and Dynajet hydraulic polymer feeders. Both technologies have been used in the field for the past several decades. The Polyblend® technology was introduced in 1972 and the Dynablend and Dynajet technologies were introduced to the market in 1985. The combination means UGSI Chemical Feed now boasts over 10,000 installations and three decades of field experience.

Our systems are designed to optimize polymer performance because they follow the latest in polymer science. These fundamental aspects are manifested in features such as:

  1. Two stage mixing with the highest energy applied first at the moment of initial wetting (MOIW) followed by a "quiescent" zone allowing for more gentle activation as polymer science dictates.
  2. Extended residence time in the "quiescent" zone to optimize the continued charge site exposure as the polymer is activated in an optimal manner.
  3. Options for pneumatic conveyance (dry polymer), economic mix tank design and secondary dilution to fit any site condition and application challenge.
  4. Control options to fit any site condition and application challenge.

Our team of trained experts can help you determine the best technology for your application based on your process goals, the type of polymer used and the volume you are treating. Contact our office for more information.


Product Documentation:


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.

Fluid Dynamics Products Application
Miniblend Liquid Utilizes patented Hydroaction concentric mixing chambers to activate simple-to-blend and difficult-to-blend polymers. Lightweight and portable. Choice of skid mounted or remote-mounted neat polymer metering pump.
Dynablend Liquid L4 and L6 Full featured liquid polymer blending system. Choice of peristaltic or progressive cavity pumps, depending on application.
Dynablend Liquid L8 and L12 Includes the same features throughout the line but in larger capacities.
Dynajet Dry Polymer Feed System Dry polymer feed system. Utilizes a blower-assisted conveyance system to transport and disperse the dry polymer prior to wetting. Typically used in applications when the polymer transfer is more than 20 feet (from the volumetric feeder to the mix tank).
Dynablend Dry Polymer Feed System Compact, high performance dry chemical preparation system to handle extreme conditions.
Accessories Numerous pump, control and instrument options are available.

Polymer Feed and Control Applications:


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.
