Mechanical / Hydraulic
- All dimensions are shown in Inches (millimeter).
- Overall Length: 40 inches (1,016 mm)
- Diameter: 7.9 inches (201 mm)
- Permeate Tube Diameter: 1.125 inches (29 mm)
Storage and Handling
- All elements are wet tested, treated with a 1% by weight percent sodium bisulfite storage solution, and then vacuum packed in oxygen barrier bags.
- Alternatively, elements are treated with tested feed water solution and then vacuum packed in oxygen barrier bags with deoxidant inside.
- To prevent biological growth during short-term storage, shipment, or system shutdown, it is recommended that elements be immersed in a protective solution containing 500 - 1,000 ppm of sodium bisulfite (food grade) dissolved in permeate.
- Permeate from the first hour of operation shall be discarded.
Feed Water
- The presence of free chlorine and other oxidizing agents under certain conditions, such as heavy metals which act as oxidation catalysts, will cause unexpected oxidation of the membrane. It is strongly recommended to remove these oxidizing agents from the feed water before operating the RO system.
- The customer is fully responsible for the effects of chemicals that are incompatible with the elements. Their use will void the element Limited Warranty.
