Enpro Technologies Introduces Breakthrough Polymer Mixing System

Enpro Technologies, providers of complete solutions for chemical systems integration for the water and wastewater industry, introduces the ParaDyne liquid polymer activation system for water and wastewater treatment applications. The newly patented system combines the ability to uniformly strip oil from oil-phase continuous polymer emulsions, while efficiently hydrating the polymer molecules to provide peak polymer performance for lower polymer consumption.

The ParaDyne liquid polymer activation system was developed by Carl Brazelton, inventor of the first commercially successful in-line polymer activation system, Polyblend, and who played an instrumental role in many of its subsequent model designs and further improvements over two decades. Brazelton chose and licensed only Enpro Technologies to specify, build, service and market the new ParaDyne system throughout the world.

"Polymers exhibit a combination of unique characteristics, including difficulty mixing with water, extremely fragile molecules following initial wetting, high viscosity once diluted, and a finite aging period required for full activation," Brazelton says. "When water and polymer come together in the activation process, there's one chance to get it right and that chance only lasts milliseconds. The ParaDyne system is designed to provide water and wastewater treatment plants with optimum polymer inversion – a new paradigm in dynamic mixing."

Dynamic Mixing

With the ParaDyne system, dilution water and neat polymer collide at the confined space created between the system's stator disc and impeller disc "inversion zone," providing for milliseconds of high energy and high uniform shear in the aqueous solution, which then moves outwardly without recirculation into the baffled mild mixing, low shear hydration zone. ParaDyne's unique impeller disc is designed with multiple vanes that extend from the inlet and the outlet. The vanes are recessed and tapered in two axes, providing rapid, even shear of the solution through the system's inversion zone, thereby controlling the time the molecules are subjected to the shear force in the confined space.

The highly robust ParaDyne liquid polymer activation system is available in a number of sizes and capacities to meet the specific need of the customer. The low maintenance system is capable of effectively activating and fully blending with water a homogenous polymer solution ranging from 0.1% to 1% concentration.

Enpro is a leading manufacturer and systems integrator of liquid and dry chemical equipment and has served the industrial and municipal markets since 1989. In addition to engineering systems for both dry and liquid polymer activation, EnPro provides an expansive line of liquid and dry chemical treatment equipment and services, including storage and process systems, silo systems, big bag systems, storage bin systems, liquid chemical feed systems, and is a Certified UL 508 panel facility.
