QUA Group LLC

QUA^® develops and manufactures both Ultrafiltration (UF) membranes and Electrodeionization (EDI) stacks.  These advanced membrane products are used in the water, wastewater, and water reuse markets. Sold exclusively through a global network of qualified OEM's, QUA's product offering includes their innovative Fractional Electrodeionization (FEDI®) stack, which has superior hardness tolerance compared to the other electrodeionization products on the market and their NSF Certified Q-SEP® Ultrafiltration (UF) membranes.

The Fractional Electrodeionization (FEDI®) stack was developed by taking into account the limitations of conventional Electrodeionization (EDI). The patented dual voltage process allows for a higher flexibility and tolerance to inlet water conditions, thus lowering the risk of scaling, and improving the plant's design economics and reliability. FEDI stacks are available in three different models which can be applied either for higher hardness tolerance or high water flow rates

Hardness is the scaling component and the main limiting factor for feed conditions in a conventional EDI. By incorporating a two-stage separation process with different voltages the FEDI® process is able to:

• Achieve a higher hardness tolerance by having distinctly different concentrate chambers with separate reject streams and thus reducing the potential of hardness scaling.
• Optimize power consumption by using higher electrical current only where required.
• Ensure the best water quality, continuously & consistently by removing a major part of the deionization load in the 'hardness removal zone', while residual ionic impurities are effectively removed in the 'silica removal zone', which stays in a polishing mode.

The current range of FEDI® products includes three distinct models:

1. FEDI-1 (Dual Voltage Operation)
2. FEDI-2 (Single or Dual Voltage Operation)
3. FEDI-2HF (Single Voltage Operation)

Our NSF certified Q-SEP® Ultrafiltration membranes are manufactured by the patented ‘cloud point precipitation process' which incorporate high-strength, hollow fibers with uniform pore size distribution and deliver superior performance. The Q-SEP® Ultrafiltration membranes are made from a hydrophilic polyether sulfone (PES) material with excellent low fouling characteristics.

Q-SEP Ultrafiltration modules can be used as dead-end filtration or in cross flow mode. The fibers are available with 0.8 mm ID fibers suitable for feed water with low turbidity and 1.2 mm ID fibers suitable to treat water with higher turbidity. These hollow fiber membranes operate under a pressurized inside-out flow configuration.

Q-SEP Features

• Superior module design
• Consistent pore sizes
• High porosity along the entire length of fiber
• Quality checks to ensure integrity of individual fibers prior to module assembly

Advantages of the Q-SEP® vs. Conventional Media Filtration:

• Improved filtrate quality
• SDI typically less than 1
• Removal of virus and bacteria
• Removal of microbiological matter
• Removal of colloidal matter
• No need to add coagulant chemicals for most applications
• Improvement of downstream Reverse Osmosis performance

Qua Mission
QUA develops, manufactures and markets advanced membrane products for water and wastewater treatment applications. Our mission is to bring to market leading edge technologies to treat challenging waters, supported by high quality customer service, and our entire organization is focused around this goal.

QUA will accomplish this mission through implementation of our core values, which include:

• Exceptional product performance
• Quality service to back up our products
• Creating long term, value-added relationships with our customers and strategic partners
• Continuous product improvement to meet the needs of our customers and the marketplace

Qua Vision
Our vision is to become the global leader in advanced membrane products to treat water and wastewater. We will develop a suite of leading edge products based on customer needs, experience and demonstrated performance. We will be strong, vigorous and nimble, with a committed workforce, solid financials, and a presence in key global markets. Our presence in key geographic markets will enable us to be closer to our customers and understand the specific requirements and regulations in these regions. Our organization is built around four pillars – R&D, manufacturing, marketing and customer service. QUA will continue to stand for quality in these four pillars of our organization.

Manufacturing
QUA’s operations include a 30,000 sq. ft. dedicated, state-of-the-art, membrane manufacturing facility with continuous online monitoring to maintain consistent quality. Supported by a quality control laboratory, this facility features custom designed equipment and dedicated product test rigs to meet the highest quality standards.

R&D
The R&D team includes 10 scientists with post graduate and doctorate qualification with average experience of 20 years, as well as 15 engineers with average experience of 15 years. The 20,000 sq. ft. R&D center contains all the necessary infrastructures to work on development, prototyping and pilot testing. The center is also equipped to simulate various challenging water conditions and rigorous testing of products in varying conditions prior to development of final product designs.

Quality Control
QUA has meticulously developed quality procedures, intermediate and online quality checks, and individual product testing to ensure excellent performance. The FEDI Fractional Electrodionization products are supported with CE conformity certificates, and Q-SEP Hollow Fiber Ultrafiltration Modules are in the final stages of securing NSF compliance. The manufacturing facility is currently undergoing a series of audits for ISO 9001, 2008 certification.
