The principle and application of reverse osmosis equipment

Released Date: Aug 13,2015 Article Source: Yuanlai Water Treatment
The principle and application of reverse osmosis equipment I. RO Reverse Osmosis Pure Water equipment The reverse osmosis device uses sufficient pressure to make the solvent (usually water) in the solution pass through the reverse osmosis membrane (or semi-permeable membrane) and separate it out. Because this process is opposite to the direction of natural osmosis, it is called reverse osmosis. After reverse osmosis treatment, the content of impurities in water is reduced, and the purity of water quality is improved. Its desalination rate can reach over 97%, and it can remove most of the colloids and large-molecular-weight organic matter in water. Reverse osmosis can adapt to various types of raw water with different salt contents, especially in water treatment projects with high salt content, it can achieve excellent technical and economic benefits. Reverse osmosis has a high desalination rate, high recovery rate, stable operation, small floor space and simple operation, which makes reverse osmosis equipment widely used in various types of desalinated water

  The principle and application of reverse osmosis equipment

  I.ROReverse osmosis pure water equipment

  The reverse osmosis device uses sufficient pressure to make the solvent (usually water) in the solution pass through the reverse osmosis membrane (or semi-permeable membrane) and separate it out. Because this process is opposite to the direction of natural osmosis, it is called reverse osmosis. After reverse osmosis treatment, the content of impurities in water is reduced, the purity of water quality is improved, and its desalination rate can reach97%It can also remove most of the colloids and large-molecular-weight organic substances in water.

  Reverse osmosis can adapt to various types of raw water with different salt contents, especially in water treatment projects with high salt content, it can achieve excellent technical and economic benefits.

  Reverse osmosis has a high desalination rate, high recovery rate, stable operation, small floor space and simple operation, which makes reverse osmosis equipment widely used in various desalination water treatment projects. Since reverse osmosis equipment removes most colloids and large-molecular-weight organic substances while desalinating, it is indispensable in the production of pure water.

EDI ultra-pure water system

EDI ultra-pure water system

Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.

Non-negative pressure water supply equipment

Non-negative pressure water supply equipment

The non-negative pressure water supply equipment can be directly connected to the municipal water supply network, making full use of the residual pressure of the original network for superimposed water supply. Fully enclosed operation does not require the construction of a domestic water tank, eliminating secondary pollution. Intelligent variable frequency voltage stabilization, energy-saving, quiet and easy installation, it is the preferred equipment for secondary water supply in high-rise residential buildings and commercial buildings.

Constant pressure water supply equipment

Constant pressure water supply equipment

Constant pressure water supply equipment is widely used in central air conditioning, floor heating, industrial closed-loop water circulation, and boiler systems. It integrates automatic pressure stabilization, automatic water replenishment, automatic exhaust, pressure relief and buffering functions. It stabilizes the pressure in the pipeline network, eliminates abnormal sounds caused by air blockage, and prevents damage from negative pressure and water shortage in the pipeline. It is an essential supporting equipment for HVAC and circulating water systems.
