Our Dry Polymer Systems

The Unmatched Reputation of Polyblend® and Dynajet

Polyblend® DP systems have an unmatched reputation for reliability. The DP system typically reduces polymer consumption by 25% or more, while substantially improving polymer performance in terms of sludge dryness, solids capture, water clarity, drainage / retention, or any other measure. In head-to-head trials, the Polyblend® DP110 Dry Polymer Feed System outperforms all other designs. While dry polymer feed systems are notoriously high maintenance items, the  Polyblend® DP Series requires the least maintenance and operates unattended for a longer interval than any other dry polymer feed system on the market.

The Dynajet technology uses a blower-induced pneumatic conveyance system to transfer up to 12 lbs of polymer per minute from the volumetric feeder to the wetting head. The polymer is naturally dispersed in the conveyance air before introduction to the dilution water for optimum polymer-particle wetting.

We Follow the Science

Our systems are designed to optimize polymer performance because they follow the latest in polymer science. These fundamental aspects are demonstrated in our feeders:

  • 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.
  • Extended residence time in the "quiescent" zone to optimize the continued charge site exposure as the polymer is activated in an optimal manner.

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.

Optimize For Your Situation with Dry Polymer 

The activation of the dry polymer can be achieved through a variety of means, including mechanical mixing, agitation, or the addition of other chemicals such as coagulants or flocculants.

The activation process is typically optimized for each specific application to ensure that the polymer is activated in the most effective way possible to achieve the desired results for your water or wastewater application.

Dry polymer has a shelf life of over 3 years if unopened and properly stored. 

The Ideal Environment for Dry Polymer Activation

Dry polymer activation is a process used in wastewater treatment to enhance the flocculation and sedimentation of suspended solids in the wastewater. In dry polymer activation, the polymer is first mixed with a small amount of water to form a concentrated solution. The concentrated solution is then added to the wastewater and mixed thoroughly to ensure that it is evenly distributed throughout the wastewater. The polymer molecules then begin to interact with the suspended solids in the wastewater, causing them to coagulate and form larger flocs that are easier to remove from the wastewater.

To create the ideal environment for the first stage of dry polymer dissolution, crucial initial wetting occurs in the DD4 disperser. Here, polymer and water are subjected to high energy created by mechanical mixing. The dry polymer is accurately metered into the high-energy mix chamber and is properly activated with water. After brief exposure, the solution exits the high-energy disperser. The point of initial polymer / water contact is visible to the operator through a clear, acrylic interface.

Low-Energy-Mix-Tank

Low-Energy Mix Tanks Create Uniformity

Most polymer mix tanks are not uniform in their mixing energy. Agglomerations form in the portions of the tank that receive the least mixing energy, while polymer chains are broken up at the tip of the rotating mixing blade.

In contrast, the Polyblend® activated polymer storage tank is specifically designed to provide fully uniform mixing intensity. The rotating impeller, known as a “hollow wing,” has a length that is more than half the width of the tank. This unique design continuously moves the solution both vertically and horizontally, creating a pump-like action that reduces agglomerations and broken polymer chains. The square tank design eliminates the potential for a damaging vortex. With minimal waste, polymer costs are reduced and polymer activation performance is improved.

The hollow wing impeller design is available for use with various tank sizes up to 2,000 gallons. The hollow wing design is standard on all Polyblend® dry polymer systems and optional on Dynajet dry polymer systems.

Dynajet dry polymer

Dynajet

The Dynajet technology uses a blower-induced pneumatic conveyance system to transfer up to 12 lbs of polymer per minute from the volumetric feeder to the wetting head, with higher capacity custom systems available.

The polymer is naturally dispersed in the conveyance air before introduction to the dilution water for optimum polymer-particle wetting. Polymer and water come together in a high flow shower of water produced by specially designed waterjets to ensure complete polymer-particle wetting.

The solution that’s created enters the mix tank where the polymer solution is ready for the mixing and aging process.

Features

  • Shower type wetting process
  • Pneumatic polymer conveyance system designed to disperse polymer prior to wetting
  • NEMA 4x control panels
  • Touch screen operator interface
  • Hoppers designed for ease of polymer handling (available in multiple configurations)
  • Stainless steel hopper
  • Rugged stainless steel variable speed Volumetric feeder
  • Stainless steel equipment skid
  • Optional dust collector for manual fill hoppers

Benefits

  • Assures thorough wetting of polymer for optimum performance, clean operation and increased reliability.
  • Increased reliability and disperses polymer to assure effective polymer-particle wetting.
  • Prevents polymer build-up at volumetric feeder, prevents plugging of polymer conveyance system.
  • Choice of polymer storage and handling systems to meet your plants specific needs.
  • Safer for the operator when loading polymer. Cleaner operation with less chance for polymer spills.
  • Flexibility to choose the control features that best meet the needs of your plant without the increased cost of customization.
