Reverse osmosis plants are designed for drinking, process and other water preparations from ions dissolved in water, as well as for desalination of seawater. In reverse osmosis plants, the main element is the reverse osmosis membrane, through which water is purified. The reverse osmosis method involves the passage of feed water through a special semi-permeable membrane. Membrane pores only pass water molecules and salt compounds through them, the size of the molecules of which roughly corresponds to the size of the water molecules. Due to the properties of water, it is possible to separate various impurities from water, mainly salts (chlorides, fluorides, sulfates, nitrates, metals of these salts, etc.). Removing salts from water is the main function of reverse osmosis plants. To purify water with salts,
After freshwater (relatively low salinity) treatment and treatment, the pressure should be 10–15 bar and up to 70 bar when descending sea water. Multistage high pressure pumps can create this pressure. The use of reverse osmosis can achieve a degree of purification up to 99.7%.
Reverse osmosis plants are used not only in the food and chemical industries, where high water quality is required, but also in certain quality standards for water used in any other industries with high-tech equipment Is required. Reverse osmosis systems are also used for saltwater desalination, for example, on marine vessels and in areas where freshwater use is limited.
- Desalination percentage of water up to 99.5%
- Productivity from 2 to 5000 m मीटर / day
The desalination plant consists of the following main units:
- Pre-treatment system (dose chlorination system, diaphragm pump, tank, feed system, filter, control panel).
- Fiscal dosing system with filtration system and membrane unit.
- Chemical treatment station
- Automatic flushing system
- Main high-pressure pump
- Electric control panel
- dosing chlorination system
