4 INCH frp filter housings supplier to share with you: Reverse osmosis technology has been widely used in various fields of industry and people's life. Industrial reverse osmosis water treatment equipment generally consists of reverse osmosis membrane elements, glass fiber reinforced plastic membrane shells, high pressure pumps, flow meters, conductivity meters, pressure protection, control boxes and brackets (stainless steel or carbon steel).
Electronic semiconductors, integrated circuit chips and packages, liquid crystal displays, high-precision circuit boards, optoelectronic devices, various electronic devices, microelectronics industry, large-scale and ultra-large-scale integrated circuits require a large amount of high-purity water, ultra-pure water to clean semi-finished products and finished products. The higher the integration level of integrated circuits, the higher the requirements on water quality. At present, the Ministry of Electronics Industry of China divides electronic-grade water quality technology into five industry standards, which are 18MΩ.cm, 15MΩ.cm, 10MΩ.cm, 2MΩ.cm, and 0.5MΩ.cm to distinguish different water quality. The secondary reverse osmosis effluent has a conductivity of 1 us / cm2 and a resistivity of more than 15 megohm / cm2.

The advanced treatment reverse osmosis system is mainly composed of a desalination device, a dosing device and a chemical cleaning system. The system can produce nearly 3000m3 of desalinated water per day, which can be used as make-up water for the circulating cooling system for production.
The importance of reverse osmosis membrane shell in water treatment:
When the reverse osmosis equipment performs the water pretreatment process, the membrane shell accessories have a protective effect on the membrane technology, which has made great progress in the production of pure water by the reverse osmosis process. The barrel, head, and slot of the reverse osmosis membrane shell have undergone rigorous lay-up design and optimized calculation details to ensure structural safety and ensure the long-term safety and stability of the water treatment system under pretreatment pressure.
Reverse osmosis membrane shell components are used as accessories to protect reverse osmosis membranes. There are two types of seam and seamless. This equipment is made of stainless steel. The end caps are made of ABS and stainless steel, sealed with silicone O-rings, with high sealing performance and long service life. Membrane shell sub card sleeve type and flange type, built-in type, the shell is made of 304 seamless stainless steel tube, good sealing performance, high pressure resistance, no aging, convenient installation and cleaning membrane.
The quality of the reverse osmosis membrane shell in the feedwater treatment directly affects the service life of the reverse osmosis membrane. Regardless of whether the feedwater quality is surface water or groundwater, there will be some organic and inorganic pollutants. If these pollutants are directly processed in the reverse osmosis system without pretreatment, those pollutants and suspended matter will remain in the membrane. On the surface, the flow channel is blocked, the pressure of the membrane element is increased, the water production and the salt rejection rate are reduced, and even serious consequences such as membrane pollution or membrane damage are caused.
At the same time, in the case where the concentration of organic matter, alternation and suspended matter in the feedwater is very high, the thickness of the water supply screen will cause high pollution to the membrane. Before discussing this issue, we must first understand how to protect the membrane shell, so as to ensure that membrane elements cannot cause pollution.
In short, the most common type of feedwater pretreatment for reverse osmosis systems is membrane element pollution. When it comes to membrane element pollution, one of the most important components has to be mentioned, that is, the reverse osmosis membrane shell, which plays an anti-pressure role in the entire system , The role of protection.
