innovative reverse osmosis water filter replacement seawater reverse osmosis
Product advantage
1. SLE Series Product Performance Stability.
2. SLE Series is dry membrane elements, so it is easy to transport and storage time extend.
3. SLE Series be used for Rural and Urban tap-water or low salinity water due to it’s High Stable rejection and low pressure Advantage.
