DA-HRFR400-ALL


Product Introduction

Daltonen Membrane HRFR series high desalination reverse osmosis membrane components are one of the highest desalination rate reverse osmosis membrane components, with a stable desalination rate of over 99.7%. In general industrial and water treatment applications, the use of a primary reverse osmosis system can achieve high-quality effluent quality. This series of 8-inch membrane components has an effective membrane area of over 37 square meters, which can achieve the expected system design and operating flux, and can meet higher water quality purification requirements at a lower cost. The HRFR high desalination and high pollution resistance series membrane components come in two sizes: 8-inch and 4-inch, mainly suitable for high pollution water sources such as electroplating wastewater, printing and dyeing wastewater, and coking wastewater.

 

Product advantages

· It can effectively reduce the energy consumption of membrane system operation and improve the economic efficiency of system operation

· Good pollution resistance and high pollution influent water quality

· 35mil special inlet channel, more resistant to pollution
