WATER AND WASTEWATER MANAGEMENT
Polymers cause flocculation in waste water making it easy to seperate off the clarified water

Selecting the proper polymer system can help process engineers deliver cleaner water; here we explore how
n the process industry, chemical polymers are added to industrial clarifiers, settling ponds, and other wastewater equipment at
various stages of treatment. This is done to comply with the US’s EPA wastewater regulations and reclaim valuable resources, These polymers promote
flocculation, a process in which small particles clump together into larger particles called flocs, which settle at the bottom. The clarified water can then be discharged for re-use, disposal, or further treatment.
SELECTING THE RIGHT POLYMER The problem with this highly effective

and economical method of removing suspended solids from wastewater is that not just any old polymer will not do. In fact, the polymer selected for the application and the preparation system that mixes and injects the product into the clarifier determines the quality of separation/clarified water, the dryness of solids, and the amount and cost of polymer required. “Selecting the correct polymer,
ensuring its proper preparation, and optimising the chemical reaction all have a significant impact on water and solids quality. A more meticulous approach to polymer and the make- down system can reduce costs by lowering the amount of product required, ultimately producing better
solids and cleaner, higher quality water,” says Shane Schmutzler, president of Port Washington, WI- based Jadair International, a provider of systems for polymer preparation, water clarification, and materials reclamation. To improve sub-par flocculation
outcomes, transitioning to superior polymers and preparation systems can boost performance without modifying other existing system components. “Replacing less effective polymers
can reduce polymer costs by up to 50% while improving the experience of the operator, facility, and community involved in the project,” says Schmutzler. He also explains that polymer
