Operating Information

• All elements are wet tested.
• Elements are 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.
• For short-term storage, shipment, or system shutdown, it is recommended that elements be immersed in a protective solution containing 500 - 1,000 ppm of food-grade sodium bisulfite dissolved in permeate.
• Permeate from the first hour of operation shall be discarded.
