2 Filtration Solutions for Desalination Applications Introduction Pall Corporation is a global leader in filtration, separation and purification technologies. Pall provides Total Fluid Management SM solutions to meet the critical needs of a broad range of customers in municipal and industrial water; biopharmaceuticals; hospital, transfusion and veterinary medicine; energy and alternative energy; electronics; aerospace; transportation; and other industrial markets. Pall Corporation provides a full line of filtration products that aim to optimize overall cost-effectiveness of desalination plants while reducing environmental impact. Our solutions include ecologically friendly Schumasoil subsea intake screens, pre-reverse osmosis (RO) glass-reinforced plastic (GRP) vessels, GRP modular racks, and cartridge filters for new and existing desalination and brackish water treatment plants. In addition, we offer full-range integrated membrane systems (IMS) that provide membrane filtration (UF/MF) pretreatment and reverse osmosis as a fully integrated membrane process. Pall s GRP vessels accommodate a wide selection of cartridge filters including: Claris filters, Marksman High Flow filters, Nexis High Flow filters, and Ultipleat High Flow filters. All of the cartridge filters offer superior dirt-holding capacity and support high flow rates with low differential pressures qualities that are ideal for RO guard filtration. Pall also offers RO pressure tube-style housings for desalination and brackish water applications. Pall s GRP modular racks accommodate high-flow filters for high-flow applications to minimize labor costs when replacing and disposing of elements, and to save floor space. GRP modular rack systems are designed for easy configuration and replacement of cartridges. One high-flow cartridge is used per each modular GRP housing. Pall s GRP RO guard filters are ideal for both conventional pretreatment of RO and for use in integrated membrane systems at desalination and brackish water treatment plants. Our wide selection of filters meets a variety of customer needs. Claris filters provide valuable RO protection in the most economical way, while Pall s full range of high-flow filters provide clients with fewer cartridge replacements and longer on-stream life. The high-flow filters are interchangeable and are designed to fit into both vertical and horizontal GRP vessels, as well as GRP racks. 2

3 GRP Series Housings Technical Information Description GRP Series housings are manufactured with polyester resins which provide superior chemical resistance to a wide range of fluids, especially acids, alkalis, seawater, and brackish water. Special design and construction consideration ensures that the GRP housings are resistant to ultraviolet light and highly corrosive environments. The fiberglass housings come in vertical and horizontal configurations to meet customers space requirements. The vessels are designed to house a variety of filters, giving customers the ability to select the type of media and removal rating for their specific seawater or brackish water application. Pall s RO guard filters are available in melt-blown depth or pleated configurations and offer high dirt-holding capacities, low differential pressures, low energy consumption, and long on-stream life. Pall s RO guard filters are designed to reduce the overall filtration costs at desalination plants by providing reliable, high-performance filtration that requires fewer element change-outs than conventional filters.

Each filter is designed for particulate contamination removal in high-volume, high-flow applications. Some of the many benefits include: Enhanced corrosion resistance of the GRP materials Minimized floor space requirement Easy and quick cartridge change-outs Lower capital costs Longer life and lower maintenance costs Consistent, repeatable performance Substantially reduced vessel clean-up time Energy efficiency due to high dirt-holding capacity and lower delta P s Claris filters offer the lowest element capital expenditure of the group of elements and are available in bulk packaging. These filters are used in vertical GRP housing configurations. Claris filters are designed to meet EPC specifications. Options are available that are certified by NSF International under ANSI/NSF Standard 42 and 61 for materials only. For more information regarding the certification, please contact Pall. For more information, see data sheet WPCLRDESALEN. A brief description of each type of filter can be found below. Claris Filters Claris filters feature highly consistent, polypropylene melt blown media with a graded pore structure that enhances dirt-holding capacity. Claris filters are free of surfactants, binders and adhesives. An extruded fibrous core (E-core) provides excellent strength and allows easy and safe cartridge incineration and disposal. Claris filters are available with a DOE option for existing housings and come in two lengths 1016 mm (40 in) and 1270 mm (50 in). Additionally, plastic and metal spring assembly end configurations are available. 8

9 Marksman High Flow Filters Marksman High Flow filters are high-capacity, high-flow polypropylene filters. Marksman High Flow filters feature a mm (6 in) large cartridge pleated geometry and are available in 508 mm (20 in), 1016 mm (40 in), and 1524 mm (60 in) lengths. These filters use Pall s proprietary Poly-Fine II media or Poly-Fine Extended Life Depth (XLD) media for highly consistent filtration. Marksman High Flow filters have an inside-to-out flow that traps contaminants inside the element. Marksman High Flow filters are available in a variety of grades to meet specific application requirements. These filters are used in both vertical and horizontal GRP housing configurations. For more information, see data sheet WPMHFDESALEN. Nexis High Flow Filters Nexis High Flow filters are large-diameter, coreless, single-open-ended depth filters. Nexis High Flow filters are manufactured using highly automated equipment and proprietary CoLD Melt technology for increased product consistency. Inside-to-outside flow traps contaminants inside the filter, preventing discharge during change-outs. With its large diameter, desired results can be achieved in high flow rate applications using significantly fewer elements and smaller housings. Nexis High Flow filters are an excellent choice when upgrading a housing. The large scale format enables easy change-outs. These filters are used in horizontal GRP housing configurations and GRP modular racks. For more information, see data sheet WPNHFDESALEN. Ultipleat High Flow Filters Ultipleat High Flow filters are coreless, single-open-ended, pleated filters with an inside-to-outside flow pattern. The filter's unique crescentshaped, pleated geometry combined with its large mm (6 in) diameter and proprietary media delivers great performance, while using considerably fewer elements and smaller housings. Ultipleat High Flow filters are well-suited for small to large desalination and brackish water treatment applications where high flow rates and high contamination ingression rates are present. Ultipleat High Flow filters provide reproducible and consistent removal efficiencies. Ultipleat High Flow filters are available in 1016 mm (40 in), 1524 mm (60 in), and 2032 mm (80 in) lengths and a range of removal ratings. These filters are used in both vertical and horizontal GRP vessels as well as GRP modular racks. For more information, see data sheet WPUHFDESALEN. 9

Multiply this value by the total system flow to determine the aqueous pressure drop. Note: for fluids other than water, multiply this value by the fluid s viscosity at the operating temperature in centipoise. This value is the pressure drop across the filter(s). It must be added to the pressure drop of the housing to determine the overall system pressure drop. For kpa/lpm, multiply mbard/lpm by Ultipleat High Flow Filters 12 Media Grade Absolute liquid 1016 mm (40 in) length 1524 mm (60 in) length 2032 mm (80 in) length type removal rating (microns) at 99.98% by particle count 13 mbard / m 3 / hr psid / 100gpm mbard / m 3 / hr psid / 100gpm mbard / m 3 / hr psid / 100gpm HDC II J Medium J Profile UY Media in Ultipleat UY Format 12 Multiply this value by the total system flow to determine the aqueous pressure drop. For fluids other than water, multiply this value by the fluid s viscosity at the operating temperature in centipoise. This value is the pressure drop across the Ultipleat High Flow filter(s) only; it must be added to the pressure drop contribution from the filter housing. 13 The test procedure used is an adaptation of ISO 4572, modified to determine the micron size above which particles are quantitatively removed. 14 Precise evaluation of the 99.98% removal efficiency for these coarse grades is not possible with the ISO modified test procedure utilized. The removal efficiency was determined by the maximum spherical particle analysis. 10
