Parameters Of A Domestic Reverse Osmosis Membrane

• 250 TDS Filtered (5µ), De-Chlorinated, Municipal Feed Water, 77˚F, 40% Permeate Recovery, 6.5-7.0 pH Range, at the Specified Operating Pressure.
• Data Taken After 30 Minutes of Operation.
• Maximum Pressure Drop for Each Element is 10psi.
• Minimum Salt Rejection is 96%.

Firstly Permeate Flow for Individual Elements may vary ± 20%.

While in storage, membrane elements must be kept sealed and moist. Consequently drying out may occur and damage the membrane permanently. Unless you must prevent elements from freezing or being exposed to direct sunlight. We tested elements are vacuum-sealed in a polyethylene oxygen barrier bag containing 3012 400 GPD Membrane Preservative and then packaged in a cardboard box. Discard the permeate for the first twenty-four hours of operation. Do not use the first full tank of permeate for drinking or food preparation. The permeate flow (product water flow) varies with feed water temperature. Review a Temperature Correction Chart. For membrane warranty information, please contact the manufacturer.

Important Operation Notes:

• When someone uses this product for the first time. Discard water obtained from the first hour of use, as it should permeate instead.
• While keep elements moist at all times after initial wetting.
• If operating limits and guidelines given in this Product Information Bulletin are not strictly followed, the Limited Warranty will be null and void.
• To prevent biological growth during prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution. Rinse out the preservative before use.
• The OEM is fully responsible for the effects of incompatible chemicals and lubricants on elements. The use of any such chemicals or lubricants will void the Limited Warranty.
