The limitations shown in Operating Limits are for general use. The values may be more conservative for specific projects to ensure the best performance and longest life of the membrane.

Notices and Guidelines

• Minimum permeate flow for individual elements is 20 percent below listed flow.
• Elements are vacuum sealed in a polyethylene bag containing less than 1.0% sodium meta-bisulfite and 10% propylene glycol solution.
• Permeate obtained from the first hour of operation should be discarded.
• Avoid static permeate-side backpressure at all times.
• These membranes may be subject to drinking water application restrictions in some countries: please check the application status before use and sale.
• For element loading use only glycerine to lubricate o-rings and brine seal.
• The customer is fully responsible for the effects of incompatible chemicals on elements. The presence of free chlorine and other oxidizing agents will cause membrane failure; the damage is not covered under warranty.
