UltraClean HRFR series high desalination reverse osmosis membrane element is one of the reverse osmosis membrane elements with the highest desalination rate, with a stable desalination rate of 99.7%. In general industrial and water treatment applications, stringent effluent quality requirements can be met with a primary reverse osmosis system. This series of 8-inch membrane elements has an effective membrane area of 37 square meters, which can not only maximize productivity, but also achieve accurate and predictable system design and operating flux. Meet higher water purification requirements at a lower cost. Available in 8-inch and 4-inch sizes.
Stable performance and high rejection rate for organics
Low operating pressures, high flux and cost saving
Meet the demand for near zero discharge
