LEFILTER's Water Treatment & Process Solutions business unit offers a wide range of quality seawater reverse osmosis (RO) components designed to reduce the investment cost and operating cost of desalination systems.
•High rate of desalination and boron removal.
•Maximum guaranteed active membrane area of 400 square feet (37 square meters)
•Maximum effective membrane area and inlet runner width (34 mil) to help reduce cleaning frequency and increase cleaning efficiency
•No oxidizing post-treatment is used in membrane production, ensuring sustainable high performance over the life of the element.
•Efficient utilization in produced-water flow-through desalination systems without impacting downstream process performance

Operating Instructions:
Dramatic changes in pressure or misflow flow should be avoided during startup, shutdown, cleaning, or other processes to prevent membrane damage.
During startup, we recommend the following procedure for gradual transition from standstill to operation:
- Inlet pressure should gradually increase over 30-60 seconds.
- The design staggered flow rate should be reached within 15-20 seconds.
- The water produced during the first hour of operation should be drained off.
