With the development of society and the progress of science and technology, in order to better meet the needs of production and people's use, membrane separation technology has been rapidly developed and widely used in many industries, such as pure water production, seawater desalination, brackish water desalination, electronic industry, pharmaceutical and biological engineering, environmental protection, food, chemical, textile and other industries. In industrial production, there are opportunities for the application of membrane technology in any process involving concentration and separation at the molecular level.

Membrane separation technology, as a new and high technology developed recently, has the advantages of high separation efficiency, energy saving, simple equipment and convenient operation. It is believed that with the further study of membrane technology and the continuous improvement of membrane technology, membrane separation technology will play an increasingly important role in industry.

Introduction to industrial equipment:

1、 Industrial pure water equipment mainly adopts reverse osmosis process, which is also known as reverse osmosis deionized water equipment. Reverse osmosis is a kind of membrane separation technology driven by pressure with the help of selective (semi permeable) membrane. When the pressure applied in the system is greater than the osmotic pressure of water inlet solution, water molecules continuously penetrate through the membrane and flow into the central pipe through the water producing channel Then the impurities, such as ions, organics, bacteria, viruses, etc., flowing out of the water at one end, are intercepted at the inlet side of the membrane, and then flow out at the outlet end of the concentrated water, so as to achieve the purpose of separation and purification.

2、 Industrial equipment composition:

The complete set of industrial pure water equipment generally includes pretreatment system, reverse osmosis device, post-treatment system, cleaning system and electrical control system. The pretreatment system generally includes raw water pump, quartz sand filter, activated carbon filter, softener (dosing system), precision filter, etc. according to the situation, ultrafiltration system can replace the existing pretreatment system. Its main function is to reduce the pollution index of raw water and other impurities such as residual chlorine to meet the requirements of reverse osmosis. The equipment configuration of pretreatment system should be determined according to the specific situation of raw water.
