Saptone FR Series membrane elements include 8-inch products and 4-inch ones， which are superior in reducing the organic pollution and inorganic fouling and advancing the cleaning recovery performance. Also, LongYuan has optimized the structure of membrane elements, adopted the widest inflow path in this field. This improves their anti-pollution performance and enables the elements to be cleaned effectively. Even under high pollution, the system can remain low pressure drop to reduce energy consumption.

FR Series RO Membrane Elements
Saptone FR Series membrane elements include 8-inch products and 4-inch ones， which are superior in reducing the organic pollution and inorganic fouling and advancing the cleaning recovery performance. Also, LongYuan has optimized the structure of membrane elements, adopted the widest inflow path in this field. This improves their anti-pollution performance and enables the elements to be cleaned effectively. Even under high pollution, the system can remain low pressure drop to reduce energy consumption.
FR series are suitable for surface water, underground water, running water and municipal water with salinity of TDS＜10000ppm. They are mainly applied for industrial water treatment including reuse of reclaimed water, refinery, papermaking, chemical filtration feed water system and surface water purification.
