New Model Expands to Five the Number of Available Sizes

June 12, 2012 -- DALLAS, June 10, 2012 – QUA®, a leading-edge developer of advanced membrane products for water and wastewater treatment applications, introduces its new smaller sized Q-SEP® Model 2008 Hollow Fiber Ultrafiltration (UF) Modules. This smaller compact module offers greater flexibility while designing smaller filtration systems particularly for commercial customers as well for other customers where water demand is low. Q-Sep 2008 is most suitable for customers such as offices, hospitals, hotels, whole house POE etc. Q-Sep 2008 is NSF certified.


QUA® will show its Q-SEP® Hollow Fiber Ultrafiltration (UF) Modules at Booth # 4805 at the ACE12 Annual Conference and Exposition this week in Dallas, TX. 



Q-SEP 2008 is a self-encapsulated hollow fiber ultra filtration membrane module (Inside-out) with a membrane surface area of 20.0 m2 (215.27 ft2). As noted above, the total length including end cap is 1015 mm, and the unit has a diameter of 225 mm (8.85 inches). The Q-SEP model 2008 module weighs 28 Kg (61.39 lbs). As with other Q-SEP models, the 2008 module is mounted vertically.


Q-SEP Hollow Fiber UF modules contain UF membranes manufactured with QUA’s “Cloud Point Precipitation” method. This innovative process ensures a high pore density along the length of the fiber and uniform pore size distribution in the membrane. Q-SEP modules deliver superior performance characteristics and product water quality that surpass the quality from conventional UF modules, with low silt density index (SDI) and excellent rejection of bacteria and viruses.


QUA was recently awarded NSF/ANSI 61 Certification by NSF International, Ann Arbor, MI, USA, for the manufacture of its Q-SEP® range of Hollow Fiber Ultrafiltration (UF) Modules. NSF/ANSI Standard 61 certification is for Drinking Water System Components – Health Effects, the recognized health effects standard for all devices, components and materials that contact drinking water.


Q-SEP UF membranes are made from a hydrophilic polyether sulfone (PES) material that provides high fiber strength and excellent low fouling characteristics resulting in higher productivity. These hollow fiber membranes operate under low transmembrane pressure in an inside-out flow configuration for superior performance. The fibers in the Q-SEP module are held firmly in place, which reduces the stress on the fibers even at high flow velocities. Uniform fiber packing limits the pressure drop variation within the module and prevents localized high fouling conditions. Unique end cap sealing design allows for high pressure operation and ease of assembly.

Q-SEP UF modules can be used as dead-end filtration or in cross flow mode. The membranes 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.




Advantages of Q-SEP UF over conventional media filtration include improved filtrate quality; SDI typically less than 1; removal of virus, bacteria and germs and well as microbiological and colloidal matter; improvement of downstream RO performance; and consistent treated water quality, irrespective of changes in feedwater quality. In addition, Q-SEP eliminates the need to add coagulant chemicals for most applications. The Q-SEP ultrafiltration fibers and modules, like all QUA products, are manufactured in a state-of-the-art membrane manufacturing facility with continuous online monitoring to maintain consistent quality.


Applications of Q-SEP UF modules include pretreatment to reverse osmosis (RO) systems (brackish and seawater applications), purification of surface and well water for potable applications, filtration of industrial water, and wastewater recycle and reuse.
