The core of reverse osmosis technology is reverse osmosis membrane. Reverse osmosis membrane is a simulation of biological semi-permeable membrane made of artificial semi-permeable membrane with certain characteristics, currently in the field of seawater desalination, industrial pure water, electronic ultra-pure water, water reuse, biopharmaceuticals, food industry separation and concentration and other fields are playing an important role. In today's water shortage, the application of reverse osmosis membrane in the field of water treatment is particularly important.

You may not know much about activated charcoal. What are the varieties of activated carbon, and what are the effects of each? Activated carbon is a traditional man-made material, also known as carbon molecular sieve. Since its advent one hundred years ago, the application field of activated carbon has been expanding, and the number of applications has been increasing. Due to different raw material sources, manufacturing methods, appearance shape and application occasions, there are many types of activated carbon, there are no precise statistics of materials, there are about thousands of varieties. Classification method of activated carbon: according to material classification, according to shape classification, according to use classification.

Styrene (chemical formula: C8H8) is an organic compound formed by replacing one hydrogen atom of ethylene with benzene. Styrene, also known as vinylbenzene, is a colorless transparent oily liquid, flammable, toxic, insoluble in water, soluble in ethanol, ether, exposed to air gradually polymerization and oxidation. Styrene is a secondary flammable liquid with a relative density of 0.907, a spontaneous combustion point of 490 degrees Celsius, and a boiling point of 146 degrees Celsius. Styrene properties are relatively stable, industrial mainly used in the manufacture of synthetic rubber, ion exchange resin, polyether resin, plasticizer and plastics and other important monomer.

A form of water filtration system called a RO (Reverse Osmosis) filtration system uses a semi-permeable membrane to filter out contaminants. High pressure is applied by the system to push water through the membrane, trapping impurities and leaving behind clean, filtered water.

Dust collector is a device that separates dust from flue gas, called dust collector or dust removal equipment. The performance of the dust collector is expressed by the amount of gas that can be handled, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. At the same time, the price, operation and maintenance costs, service life and difficulty of operation and management of the dust collector are also important factors to consider its performance. Dust collectors are commonly used facilities in boilers and industrial production.

Whether it is pure water preparation or industrial wastewater reuse, while using reverse osmosis (RO) technology, it is bound to produce a certain proportion of concentrated water. Because of the working principle of reverse osmosis, the concentrated water in this part often has the characteristics of high salinity, high silica, high organic matter, high hardness and so on. In view of such characteristics, we often need to choose some measures for concentrated water according to the specific situation, in order to avoid wasting water resources and obtain the purpose of reducing cost and increasing efficiency.
