SW22-8040 / SW22-4040 elements can separate salts from water and increase permeability while offering superior salt rejection. They are ideal for use in large-scale industrial and municipal water treatment systems.
Test Condition: Feed Water Pressure 1.55MPa (225 psi); Feed Water Temperature 25 °C (77 °F); Feed Water Concentration 32,000 ppm NaCl; Feed Water pH 8; Permeate Recovery 15%.
Operation Condition 
MaximumOperating Pressure 55 bar(800 psi) 
Maximum Operating Temperature 45℃（113℉） 
Maximum Pressure DropperElement 1.0 bar (15 psi) 
pH Range, ContinuousOperation 2-11 
pH Range, ChemicalCleaning 1-13 
Maximum Feed Silt DensityIndex (SDI15) 5.0 
Free Chlorine Tolerance < 0.1ppm 
Note 
1. Permeate flow rates for individual elements may vary±15%. 
2. Membrane active areas may vary by ±4%. 
3. Stabilized salt rejection is generally achieved after continuous use for 24-48 hours, depending on feed water qualities and operating conditions.
