All elements of TM720-400 are wet tested, treated with a 1% by weight percent sodium bisulfite storage solution,and then vacuum packed in oxygen barrier bags, or 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 Toray elements be immersed in a protective solution containing 500 - 1,000 ppm of sodium bisulfate (food grade) dissolved in permeate.
Permeate from the first hour of operation shall be discarded
The customer shall be fully responsible for the effects of chemicals that are incompatible with the elements. Their use will void the element of Limited Warranty.
Product Warranty 1 Year against Manufacturing Defects Only
Toray 8040 Membrane is a Reverse osmosis (RO) membrane used in water purification process, these are semi permeable membranes which separate ions, unwanted molecules and larger particles from processed water. Permeate water is forced through these membranes with the use of pressure built in with the help of a pumping system.
