Important Information

Proper start-up, operation, and maintenance are essential to prevent membrane damage and ensure system performance. Abrupt pressure variations should be avoided during start-up, shutdown, or cleaning. The system should be flushed to remove shipping solution and residual air prior to start-up. For detailed procedures, refer to the Ultrafiltration Technical Manual (Form No. 45-D00874-en).

For extended system shutdowns, injecting a storage solution into the membrane modules is recommended to control biological growth.

The use of this product does not inherently guarantee the removal of cysts and pathogens from water; effective reduction depends on complete system design, operation, and maintenance. NSF/ANSI 61 and 419 certified drinking water modules require specific conditioning procedures before producing potable water.
