● During the first hour of initial use of the membrane element, the produced water shall be drained and not used.
● Dry membrane elements are shipped without preservation solution. Once wetted, the elements must be kept moist at all times.
● Feed water pressure should be increased gradually over a period of 30–60 seconds; otherwise, irreversible damage to the membrane element may occur.
● Back pressure on the permeate side must be avoided at all times.
● Wet membrane elements are tested with water before shipment, preserved in a 1.5% sodium bisulfite solution (10% propylene glycol antifreeze added in winter), and then vacuum-packed.
● For long-term system shutdowns, to prevent microbial growth, it is recommended that the membrane elements be immersed in a 1.5% (w/w) food-grade sodium bisulfite preservation solution, which should be replaced regularly.
● Users must strictly follow the operating limits and guidelines specified in this manual; otherwise, the company shall not be liable for any consequences arising therefrom.
● Users are strictly prohibited from using any chemicals that may damage the membrane elements during storage and operation. The company shall not be liable for any consequences resulting from the use of such chemicals in violation of this requirement.
