BW 4040 HF Brackish Water Membrane 4″X 40″ Replace DOW BW30-4040 & CSM RE4040-BE. Keensen BW 4040 HF 2400GPD Commercial RO Membrane. Reverse Osmosis membrane elements for commercial drinking water systems are the industry’s most reliable method of water filtration. Advanced membrane technology and automated fabrication allow these elements to deliver consistent performance that equipment suppliers, water treatment dealers, and residential customers can rely on. Our ISO9001 rated membranes are rated at 60 psi and will purify about 20% more water than competitive elements rated at 60 psi. We suggest changingyour membrane every 2 years. 2400 Gallon Per Day Membrane for Commercial Reverse Osmosis systems. Certified to ISO 9001 Standards. Removes particles down to 1/10,000th of a micron removing 98% of impurities including organic, inorganic contaminates, chemicals, ETC. Provides stable, high rejection of contaminates even with high TDS water sources. Advanced membrane technology with innovative thin layer composite membrane design. More consistent performance with less fouling requiring less frequent cleaning and changeouts. 100% dry-stored membrane maximizing shelf life. The first full tank of permeate should be discarded, DO NOT use this initial permeate for drinking water or food preparation as it may contain carbon fines and manufacturing by-products. Keep membrane moist at all times after initial wetting. To prevent biological growth during prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution. The membrane shows some resistance to short-term contact with chlorine (hypochlorite). Continuous exposure, however, may damage the membrane and should be avoided. It is applicable to the desalinationof surface water, groundwater and water treatment with salt concentrationbetween 2000 and 8000ppm. It can be widely used in the medicine, chemicalindustry, beverage, electricity and other various industries etc. Active Membrane Area ft. Permeate Flow GPD(T/D). Stable Rejection Rate (%).
