Operating Information
- Elements are wet tested and treated with a 1% by weight sodium bisulfite storage solution, then vacuum packed in oxygen barrier bags. Alternatively, they may be treated with tested feed water solution and vacuum packed with deoxidant inside.
- For short-term storage, shipment, or system shutdown, immersion in a protective solution of 500 - 1,000 ppm sodium bisulfite (food grade) dissolved in permeate is recommended to prevent biological growth.
- Permeate from the first hour of operation shall be discarded.
- The use of chemicals incompatible with the elements will void the Limited Warranty.
