General Handing Procedures
Store in a cool and dry place (below 45°C) away from sunlight.
Permeate from the first hour of operation should be discarded.
Keep elements moist at all times after initial wetting.
To prevent microbial growth in the Wet Membrane Element, it is recommended to wash it with a 1.0% Sodium Metabisulfite (food grade) solution, followed by vacuum-bag packing the
Membrane Element and storing it in a cardboard box.
Only use chemicals compatible with the membrane elements and components. Bright Star Water will not accept any responsibility for the use of incompatible chemicals.
