Compact UF module is targeted at small filtration systems
Q
ua Group Llc, a developer of membrane products for water and wastewater treatment, has introduced its compact Q-Sep Model 2008 ultrafiltration (UF) module. This module offers greater flexibility for designers of small filtration systems, particularly for commercial customers, and for applications where water demand is low, says the firm. It is most suitable for use in offices, hospitals, hotels or at the point-of-entry of a water supply for an entire house. Q-SEP 2008 is a self-encapsulated hollowfibre UF membrane module that has a membrane surface area of 20.0 m2 (about 215 ft2). The total length of the unit, including the endcap, is 1015 mm (40 inches), and it has a diameter of 225 mm (around 9 inches). It weighs 28 kg (about 62 lb). As with other Q-Sep models this unit is mounted vertically. Q-SEP modules contain UF membranes that are manufactured using what the company refers to as its ‘cloud point precipitation’ method. This process ensures that there is a high pore density along the length of the fibre and a uniform pore size distribution in the membrane. Qua claims that Q-SEP modules deliver superior performance characteristics and product water quality, which surpasses the quality of water generated by conventional UF modules – with a low silt density index (SDI), and excellent rejection of bacteria and viruses. These modules are made from a hydrophilic polyethersulfone (PES) material that provides high fibre strength and excellent, low-fouling characteristics, which improves productivity. The membranes operate under low trans-membrane pressure in an inside–out flow configuration. The fibres are held firmly in place, which reduces the stress placed on them, even at high

flow velocities. Uniform fibre packing limits the variation in pressure drop within the module and prevents localised, high fouling conditions. According to Qua, Q-SEP UF offers a number of advantages compared with conventional media filtration. These include improved filtrate quality; an SDI that is typically less than 1; the ability to remove virus, bacteria and microbiological, and colloidal matter; improved downstream RO performance; and consistent treated water quality, irrespective of changes in feed-water quality. In addition, for most applications, the technology eliminates the need to add coagulant chemicals. Q-SEP UF modules can be used in dead-end filtration or in cross-flow mode. The membranes are available as 0.8-mm ID fibres, which are suitable for feed-water with low turbidity, and 1.2-mm ID fibres for applications involving water with a high turbidity. These modules are designed for a range of uses, including pretreatment for reverse osmosis (RO) (brackish and sea-water), the purification of surface and well water for potable applications, filtration of industrial water, and wastewater recycling and reuse. QUA was recently awarded NSF/ANSI 61 Certification by NSF International for the manufacture of its Q-SEP range of UF modules (Membrane Technology March 2012, page 5). ‘NSF/ANSI Standard 61 Drinking Water System Components – Health Effects’, is the standard that establishes minimum health effects requirements for materials, components, products, or systems that come into contact with drinking water, drinking-water treatment chemicals, or both.
