DescriptionProduct Description :Hydranautics – CPA High Rejection MembranesHydranautics membranes are used to treat a wide range of highly variable waters as either primary treatment or as pretreatment to reverse osmosis (RO) and nanofiltration (NF).Compared to conventional pretreatment, Hydranautics combine benefits of high recovery and low footprint requirement due to its optimized membrane area and novel cleaning regimes.CPA (Composite Polyamide) elements set the standard for RO membrane elements – over 600 million gallons per day of pure water are produced by CPA elements for global municipalities and industries.Advantages99.7% nominal rejection.high TOC, silica and hardness rejection.Specifications:Membrane TypeComposite PolyamideMaximum Operating Temperature45ºC (113ºF)Maximum Operating Pressure600 psi (41 bar)Maximum Feed Flow Rate 4040 Elements16 gpm (3.6 m3/h)Maximum Pressure Drop15 psig (1.0 bar)pH Range, Continuous Operation2 - 10pH Range, Short-Term Cleaning (30 min.)1 - 13Maximum Feed Silt Density Index (SDI)SDI 5Free Chlorine Tolerance< 0.1 ppmSaltRejection %99.5 %Maximum Feedwater Turbidity1.0 NTU
