TRILITE BWULE-4040

TRILITE BWULE-4040, Ultr Low Pressure Reverse Osmosis Membrane

• Low operating pressure (approximately half of standard RO membranes)
• Reduced energy consumption
• Lower initial system cost (smaller pumps, piping, valves, and related equipment)
• Suitable for feed water with TDS < 1,000 ppm
• Applications: Drinking water, low-salinity industrial water, food and pharmaceutical industries

Test Conditions: 

1.  Operating Pressure 100psi (0.69Mpa / 7.03kgf/cm2)
2. Temperature 25℃ (77℉)
3. Tested at 500mg/L NaCl Solution.
