Water treatment product
Reverse Water osmosis
The cities and regions that are facing a shortage of surface and underground fresh water resources and are mainly located next to the seas or on the salt water table or on the edge of the brackish water should make maximum use of these resources to provide the water they need. Therefore, for these areas, it is necessary to use new technologies and solutions to provide fresh water.
The Possibility of Using Infinite Resources of Sea Water& Underground Resources in This
System
By using this system, fresh and potable water can be easily obtained in areas that are facing a shortage of fresh water or a water crisis and are close to the sea.
High Efficiency
Compared to water treatment by distillation method, water wastage is much less in the _Water treatment process by reverse osmosis when TDS - 4500 ppm. Typically, recovery amount in the RO system is approximately between 50 and 58%.
Improving The Water Color And Taste
The reverse osmosis system produces clear blue water by removing turbidity and dissolved ions (such as lead) that reduce the quality of water taste. As a result, water treated by reverse osmosis has a bettertaste compared to tap water.
Economical And Low Energy Consumption
Compared to thermal methods of water purification, reverse osmosis consumes less energy and if the water TDS is lower than 45000 ppm and it does not to have the problems related to high temperature sedimentation, cloggings and corrosion
Remove All Unwanted Particles Including
Ions And Heavy Metals
The reverse osmosis treatment method is able to remove ions soluble in water such as lead, iron, manganese, etc. In addition to damaging industrial equipment, these ions also cause damage to health
DESALINATION BY REVERSE OSMOSIS METHOD
Reverse osmosis is a form of filtration under pressure and the filter of which is a semi-permeable membrane. The force required to overcome the osmotic pressure in reverse osmosis water desalination is created by using high pressure pumps. Therefore, water enters the dilute side from the thick side by passing through the semi-permeable membrane. This semi-permeable membrane can remove many types of molecules and ions from water, therefore, it is used in both industrial processes and drinking water production.
The pressure required for the pump depends on the salt concentration in the water to overcome the osmotic pressure. This technology can remove viruses and chemical substances such as metal ions, lead, arsenic, fluoride, radium, etc. and radioactive substances such as plutonium, radioactive and strontium, which cause water pollution. Desalination is the most important application of reverse osmosis process in today's world. It consists of several parts: 50% desalination of sea water and brackish water, 40% high purity water for use in (pharmaceutical, electrical and energy production industries) and 10% urban and industrial water disinfection system.
Drinking Water Production
Pollutants such as lead, bacteria, viruses that can be transmitted by water, etc. in water have harmful effects on human health and body. Since the reverse osmosis system has the ability to remove these pollutants, it produces clear water without harmful pollutants.
Electronics Industry
The reverse osmosis water treatment system in the electronics industry can be used to supply water needed for battery making, water needed for the production of microelectronics, and water used in the production of semiconductors, devices, and optical fiber.
Pharmacology
Due to the presence of salts and impurities in the drinking water of the urban water supply system, it sometimes makes it impossible to use this water in this industry. Reverse osmosis can be used to ensure the desired quality of this water, which can reduce impurities by 98%.
Chemical Industry
In this context, it is possible to supply water with the desired quality needed for the production of cosmetics and health products, water needed for the electroplating industry, water needed for the dyeing and printing industries, and water needed for laboratory washing using a reverse osmosiswaterpurification system.
Agriculture Industry
Desalination of industrial water in this industry is very important to prevent damage to agricultural products. As a result, the water used in the irrigation department is desalinated using a reverse osmosis filtration system so as not to harm the plants.
Power plant/Refinery/Petrochemical
Purification of the water used in the steam boiler prevents the formation of deposits in the turbine blades and the loss of its balance, which ultimately disrupts the electricity production process. As a result, the use of reverse osmosis water purification system in the powerplant helps a lot in electricity production
Food Industry
Preventing corrosion and sedimentation is one of the applications of water purification used in steam boilers.
Because boilers are the most important part of the food production industry. In addition, the reverse osmosis system is also used in the food industry to concentrate liquids.
Water Supply For Heating & Cooling Systems
Low quality water entering the boiler increases energy consumption, reduces the quality and purity of produced steam, and ultimately reduces production and quality. Application of reverse osmosis is in the water supply circuit of the boiler and increases the reliability of production and reduces the cost of operation
