Feed water

• Maximum Feed Silt Density Index (SDI): SDI 5
• Free Chlorine Toleranceᶜ: <0.1 ppm

ᶜ Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Oxidation damage is not covered under warranty.

General Guidelines

• Keep elements moist at all times after initial wetting.
• To prevent biological growth during prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution.
• Avoid static permeate-side backpressure at all times.
• Avoid any abrupt pressure or cross-flow variations on the spiral elements during start-up, shutdown, cleaning or other sequences.
• During start-up, feed pressure should be increased gradually over a 30-60 second time frame.
• During start-up, cross-flow velocity at set operating point should be achieved gradually over 15-20 seconds.
• The use of this product in and of itself does not necessarily guarantee the removal of cysts and pathogens from water.
