INDUSTRIAL SEPARATE BED DEIONIZER High Purity Industrial Packaged System (Twin System with carbon Filtration Tanks shown) 1 P age
Deionization is the removal or reduction of positive ions called cations and negative ions called anions from the water supply. High purity water from 50 to 1 MICROSIEMENS/CM or better can be produced from typical water sources. The cation resin is converted to the hydrogen form and exchanges positive ions for hydrogen. The Anion resin is converted to the hydroxyl form and exchanges the negative ions for hydroxyl. This ion exchange process removes the majority of the of dissolved minerals and produces deionized water (H2O). Separate bed systems utilize one vessel for the cation regeneration and one vessel for the anion regeneration process. This ion exchange process does not reduce the bacterial count of the water. Composite Pressure Vessels are constructed of Industrial grade fiberglass with polyethylene inner shell. They provide outstanding durability and higher corrosion resistance than carbon steel vessels (Chemical resistant Vinylester lined composite vessels are also available). A composite tank weights are about 1/3 less than steel tanks and cost less. ASME code certified vessels are available in sizes over 18 inches. FDI systems are standard skid mounted with interconnecting piping and isolation valves. Resins are designed specifically for deionizer applications, and typically regenerating with 6.4 lbs of 100% HCI per Cubic foot of cation resin and 8.0 lbs. of 100% NaOH per cubic foot for anion resin. Lakeside resins provide high chemical and physical stability, lower pressure drop and greater resistance to bead breakage. Strong or weak base resins are selected based upon the customer s water quality requirements. Type 1 or 2 Anion resins are selected based upon the silica residuals required for the specific application. Standard systems utilize pressure compensating eductors for drawing chemical. Underdrain The radial hub underdrain uses high quality schedule 80 PVC pipe and fittings, delivering flows uniformly over the entire bed with a minimum pressure drop. The.010 PVC slotted laterals provide high flow rates and reliable service. 2 P age
Water Deionizer Systems for Industrial Solutions Thermoplastic Diaphragm Valve Nest design allows each valve to be exactly designed and sized for the required functions, providing the most cost effective, efficient and serviceable system in the market. Backwash and rinse flow rates are controlled with automatic self-regulating flow control valves. Sample valves and pressure gauges for the inlet, outlet and dilute chemical are provided on each vessel. Standard PVC piping configurations include a boiler drain down valve on each vessel. Allen Bradley PLC control package comes standard with 6 HMI EZ color touch screen with user friendly programming. The main screen can be designed to display a variety of parameters such as: water quality, current flow rates, tank status, flow totalizetion, high conductivity alarms and remaining batch in gallons for each train of equipment. Lakeside PLC solenoid system features a hold, advance, resume, termination or close of all valves function, for fast, easy field service. Fully automatic or semiautomatic operation on either batch (flow sensor), conductivity or both. Options include: custom displays; ph or ORP meters; acid & caustic percent meters. Recirculation Systems are a standard feature that provides low flow protection and allows the unit to sit at zero flow and maintain optimum water quality. This eliminates the need for a pre-rinse, which minimizes the in service delay and saves on raw water use plus waste water generated. The recirculation system is also used in the last step of the regeneration process to recirculate to quality. Sediment strainers are standard equipment on the cation and anion outlet piping. Operating Parameters: Pressure 30-100 PSIG Temperature range 35F-100F Electrical: 120vac, 60Hz NEMA 4X FRP rated electrical enclosures. DRAIN PIPING REQUIREMENTS: Max 10ft vertical and discharged to an atmospheric floor drain sized to handle the maximum rinse rate of the system. (Maximum recommended horizontal length is 25ft) Chemical day tank locations should be within 10 feet from the unit (not included on standard equipment). 3 P age
