Operating Information
1. For the recommended design range, please consult the latest HYDRAMEM technical bulletin, design guidelines, or call an application specialist. If the operating limits given in this product information bulletin are not strictly followed, the Limited Warranty will be null and void
2. All elements are wet tested, treated with 1% by weight sodium Meta bisulfate preservative solution, and then vacuum packed in oxygen barrier bags. To prevent biological growth during short term system shutdown, it is recommended that HYDRAMEM elements be immersed in a protective solution containing 500-1000 ppm of sodium Meta bi sulfite dissolved in permeate. Rinse out preservative before use
3. Permeate from the first hour of operation should be discarded
4. The customer is fully responsible for the effects of chemicals that are incompatible with the elements. Their use will void Limited Warranty
5. For element loading, use only the recommended silicon lubricant. The use of petroleum based lubricant or vegetable based oils may damage the element irreversibly
6. Membranes shows some resistance to short-term attack by chlorine (Hypochlorite).Continuous exposure may damage the membrane and should be avoide
