Description
The A-Series, family of proprietary thin-film reverse osmosis membrane elements are characterized by high flux and high sodium chloride rejection. AK Low Pressure Brackish Water Elements are selected when high rejection and low operating pressures are desired. These elements allow significant energy savings since good rejection is achieved at operating pressures as low as 100 psi (689 kPa).
Typical Operating Pressure: 100 psi (689 kPa)
Typical Operating Flux: 10-20 GFD (15-35 LMH)
Maximum Operating Pressure: 600 psi (4,136 kPa)
Maximum Temperature Continuous operation: 122°F (50°C),
Clean In Place (CIP): 122°F (50°C)
pH Range Optimum rejection: 7.0-7.5,
Continuous operation: 2.0-11.0,
Clean In Place (CIP): 1.0-13.0(1)
Maximum Pressure Drop Over an element: 12 psi (83 kPa)
Per housing: 50 psi (345 kPa)
Chlorine Tolerance 1,000+ ppm x hours,
dechlorination recommended
Feedwater NTU < 1 SDI 15 < 5
