Operating Information
All elements are wet tested. They are treated with a 1% by weight percent sodium bisulfite storage solution and vacuum packed, or treated with tested feed water solution and vacuum packed with deoxidant.
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.
