NITTO DENKO HYDRANAUTICS High Flow, High Rejection, Low Fouling Brackish Water RO Membranes CPA5-LD from the LD Technology™ innovative low fouling membranes, achieves the highest flow and highest salt rejec- tion for the most difficult of brackish feed water conditions Where ultrahigh purity water is required under difficult feedwater conditions, the CPA5-LD gives the most desirable combination of high rejection and high flow. For industries such as power, semiconductor, food and beverage, where high purity water is critical to operations, CPA5-LD gives you the most desirable combination of CPA5-LD helps reduce RO system power consumption and the membrane resistance to biological and colloidal fouling helps reduce the number of cleanings required, lowering the overall cost of your operation. • Boiler makeup water for power generation • Ultrapure water for semiconductor manufacturing • Ultrapure water for pharmaceutical industries • Industrial waste water recycling • Zero liquid discharge/HERO process • High permeate flow - • High salt rejection - • High rejection of boron - 92% colloidal fouling • Greater tolerance to high pH • Lower energy consumption Permeate Flow Salt Rejection Applications Data: pH Range, Continuous (Cleaning) Maximum Feed Flow * The limitations shown here are for general use. For specific projects, operating at more conservative values may ensure the best performance and longest life of the membrane. See Hydranautics Technical Bulletins for more detail on operation limits, cleaning pH, and cleaning temperatures. Test Conditions:
