JX Reverse Osmosis Membrane Selection And Buying Guide

Reverse osmosis membrane is a kind of membrane applied in wastewater treatment, when choosing and purchasing reverse osmosis membrane, you can refer to the following aspects:

● Type of membrane material: There are a wide variety of membrane materials for reverse osmosis membranes, including polyether ester membranes, polyether membranes, polypropylene membranes, and so on. Membranes of different materials differ in desalination efficiency, pollution resistance and chemical resistance. When selecting membrane materials, comprehensive consideration should be given to the actual use environment, water quality load and maintenance costs.

● Water permeability: Water permeability is one of the important indicators of reverse osmosis membranes, which is usually evaluated by salt retention rate and water flux. The higher the salt retention rate, the better the desalination effect of the membrane and the purer the water quality. The higher the water flux, the stronger the film's processing capacity and the longer the backwash cycle. During the purchase process, the appropriate salt retention rate and water flux should be selected according to actual needs.

● Application scenarios: according to the different scenarios of sewage treatment, industrial wastewater treatment and water quality, such as high salt wastewater, such as the selection of reverse osmosis membrane desalination rate is high, high-pressure reverse osmosis membranes, while the treatment of general seawater, seawater desalination and other application scenarios, and boiler water reuse and other reverse osmosis membrane application scenarios, you can choose seawater desalination membrane or low-pressure reverse osmosis membrane.

● Anti-pollution performance: pollution is one of the important factors affecting the service life and performance of reverse osmosis membrane. Selecting membranes with good anti-pollution performance can reduce the cleaning frequency and maintenance cost of the membrane. During the procurement process, reference should be made to the anti-pollution index of the membrane material, and attention should be paid to the cleaning method and cycle of the membrane to ensure stable operation of the membrane.

Inlet TDS ≤ 1000ppm can choose ultra-low pressure membrane element feed water;

3000ppm ≥ TDS ≥ 1000ppm can choose anti-pollution membrane element feed water;

TDS≥3000ppm can be selected from brackish water desalination membrane elements.

TDS≥5000PPM can choose desalination membrane element.

General.

Water production <4T / H reverse osmosis equipment more selection of JX-4040 membrane elements.

0.25 tonnes / hour reverse osmosis equipment, choose 1PC JX-4040 membrane, 0.5 tonnes / hour need 2PCS , 1 T / hour need 4 PCS, and so on.

Water production ≥ 4T / H reverse osmosis equipment, more than JX-8040 membrane elements;

8040 membrane element is about 1 tonne/hour, 4 tonnes/hour reverse osmosis equipment on the choice of 4PCS  JX-8040 membrane elements.

When choosing reverse osmosis membranes, it is necessary to consider them comprehensively according to the actual demand and the use environment, and choose reliable suppliers to ensure product quality and after-sales service.
