Application of Reverse Osmosis Systems Supplier Technology in Pre-Salt Treatment
At present, there are no more than 4 ways for a water purifier to filter water: microfiltration, ultrafiltration and reverse osmosis. Reverse osmosis technology is widely used in a variety of reverse osmosis water purifier equipment. First, understand what reverse osmosis is called in filtered water. Reverse osmosis is also called reverse osmosis, which is a membrane separation operation that takes pressure difference as a driving force to separate the solvent from the solution. Because it is opposite to natural infiltration, it is called reverse osmosis. According to different osmotic pressures of different materials, reverse osmosis pressure greater than the osmotic pressure, i.e. reverse osmosis method, can be adopted to achieve the purposes of separation, extraction, purification and concentration.
Reverse Osmosis Systems Supplier

Reverse osmosis membrane can intercept various inorganic ions, colloidal substances and solute macromolecules in water, thus obtaining purified water. It can also be used for preconcentration of macromolecular organic solution. Reverse osmosis has developed rapidly in the past 20 years due to its simple process and low energy consumption. Reverse osmosis has been widely used in seawater and saltwater desalination (see brine), boiler water softening and wastewater treatment, and combined with ion exchange to produce high purity water. Its application scope is expanding. It is used for the concentration of dairy products and fruit juice, as well as the separation and concentration of biochemical agents and biological agents.
Reverse osmosis technology is commonly used in seawater, saltwater and freshwater, water softening treatment, wastewater treatment and purification, purification, concentration and separation of food, pharmaceutical industry and chemical industry. In addition, the application of reverse osmosis technology in pre-salt treatment has also achieved good results, reducing a load of ion exchange resin to more than 90%, and reducing the regeneration dose of resin to about 90%. Therefore, reverse osmosis not only saves cost but also is beneficial to environmental protection. Reverse osmosis technology can also be used to remove particulate matter, organic matter and colloid from water. It plays a good role in reducing the pollution of ion exchange resin and prolonging the service life of ion exchange resin.
The basic principle of reverse osmosis:
The same volume of a dilute solution (e.g. freshwater) and concentrated solution (e.g. seawater or brine) are respectively placed on both sides of the container with a semi-permeable membrane in the middle. The solvent in the dilute solution will naturally pass through the semi-permeable membrane and flow to the other side of the concentrated solution. The liquid surface on one side of the concentrated solution will be higher than the liquid surface of the dilute solution, forming a pressure difference to reach the osmotic equilibrium state. This pressure difference is osmotic pressure. The osmotic pressure depends on the type, concentration and temperature of the concentrated solution and is independent of the properties of the semi-permeable membrane. If a pressure greater than the osmotic pressure is applied to one side of the concentrated solution, the solvent in the concentrated solution will flow into the diluted solution. The flow direction of the solvent is opposite to the original permeation direction. This process is called reverse osmosis.
