Can Your Storage System Meet the Challenges of Polymers?

Polymers are used in wastewater treatment plants to flocculate or coagulate suspended solids to produce large curds of solid materials. They also aid in dewatering digester cake, in order to reduce the water content and permit easier, less expensive transporting of waste materials to the landfill.

Polymers present unique storage challenges and require customized storage solutions to keep your workers safe and your costs low. Let’s explore these challenges and solutions.

Polymer Storage Challenges

Cationic and anionic are high molecular weight polymers. Because of their high molecular weight, polymers are very slippery. They can pose a safety hazard if they spill onto the floor or the deck of the walkway.

Polymers can also be a stress cracking agent, as well. The chemicals can be manufactured at elevated temperatures and may be delivered to your facility before they have cooled all the way down. If that is the case, the heat can compromise the strength of the tank wall. We can help you correct for that by increasing the temperature storage requirements of the tank, as needed.

Polymers can be delivered “neat,” or concentrated, but they may require blending. If so, your chemical storage tank will need to be designed and engineered to meet the unique challenges that blending introduces.

Because of these unique challenges, the correct storage tank is crucial when it comes to storing polymers.

Polymer Storage Tips

Because polymers present unique challenges, it’s important to design a storage system that will properly meet those challenges. Be sure your storage solution meets the following standards.

  1. Superior tank strength. High-density cross-linked polyethylene (XLPE) offers superior SAFE-Tankstrength for storing high-weight polymers. Poly Processing’s XLPE tanks often provide 15-20 years of service in this application.

  2. Leak prevention. To reduce the potential for leaks and to minimize slips, it’s important to limit sidewall penetrations of the storage tank. With Poly Processing’s slope bottom IMFO® system, the flange is molded into the bottom of the tank, minimizing sidewall fittings and the potential for leaks. The flange is created from the same material as the tank – not inserted during or after production. This gives the IMFO® system the superior tank strength needed for storing heavy weight polymers.

  3. Easy blending. Open-top tanks are available in a variety of sizes. Tanks can be highly customized to accommodate a mixer used in your operation.

  4. Minimal Corrosion. As opposed to steel or fiberglass, Poly Processing’s XLPE tanks offer a cost-effective, durable, high-strength storage solution that resists corrosion.

Store Your Polymers Properly

Polymer chemicals present unique challenges that require specialized storage solutions. Be certain that your storage system is properly designed and built to meet these challenges.
