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%.
Permeate Flow for Individual Elements may vary ± 20%.
While in storage, membrane elements must be kept sealed and moist. While drying out may occur and damage the membrane permanently. To prevent elements from freezing or being exposed to direct sunlight, we take additional measures. Well tested elements are vacuum-sealed in a polyethylene oxygen barrier bag containing 2012 100 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 this product is used for the first time, permeate water obtained from the first hour of use should be discarded.
- Also keep elements moist at all times after initial wetting.
- If you do not strictly follow the operating limits and guidelines stated in this Product Information Bulletin, the Limited Warranty will be 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.
