Frost & Sullivan Lauds The QUA® Group's Consistent Growth On The Strength Of Its Innovative EDI And Ultrafiltration Membrane Systems

MOUNTAIN VIEW, Calif., March 27, 2013 /PRNewswire/ -- Based on its recent analysis of the industrial water and wastewater treatment technology market, Frost & Sullivan recognizes the QUA Group with the 2013 North America Frost & Sullivan Award for New Product Innovation. The QUA Group's Fractional Electrodeionization (FEDI®) and hollow fiber ultrafiltration membrane (Q-SEP®) utilize proprietary technology to maintain distinct process and production patents to stand out in a competitive market. Both the FEDI and QSEP products have bolstered end users' goals, such as lower operational costs, operational flexibility and efficient treatment capabilities.

By addressing key challenges in both FEDI and Q-SEP applications, the company has come up with unique design features for both products. The three key design features for its Q-SEP ultrafiltration systems are higher fiber strength, uniform pore distribution and consistent treated water quality. The company conducted a two-year patent design review, along with a differentiated manufacturing process, to develop a core fiber that maintained its mechanical integrity throughout the lifespan of the membrane system.

"Achieving a uniform pore distribution within the overall design allows the Q-SEP ultrafiltration membranes to improve reverse osmosis performance further down the process cycle—a key achievement which differentiates QUA from most competitors," said Frost & Sullivan Industry Analyst Eric Meliton. "As a result, the Q-SEP ultrafiltration membranes offer a consistent treatment quality, maintain a high level of bacteria and virus rejection during operation, and provide a lower silt density index than competing products."

Also, the innovative design of the Q-SEP ultrafiltration membrane in most applications eliminates the need for coagulant chemicals, which reduces operational costs.

Meanwhile, the key design features for the FEDI system include reduced susceptibility to scaling and better handling of varying feed water quality. EDI systems have traditionally faced some resistance to adoption in the high-purity industrial water treatment market due to scaling challenges and high operational costs. Acknowledging these issues, the QUA Group designed its FEDI system to utilize a dual voltage process, by incorporating a two-stage separation process with different voltages to achieve a higher hardness tolerance by having distinctly different concentrate chambers with separate reject streams and thus reducing the potential of hardness scaling. This design alteration reduced affinity to scaling, and simultaneously lowered relevant operational and energy costs.
