Industrial desalination machine
osmosis refers to a process in nature in which freshwater tends to migrate to saline water. This occurs over and over during the day in the human body and in the kidneys, which can also be seen in the process of absorbing water from the earth by the roots of the trees. The reverse osmosis works exactly the photo of this process, in which the saltwater migrates to the fresh water and the ions and minerals in the water are removed by the semi -trawed membrane. There is a need to reduce water salt. Reverse osmosis is a physical separation process in which the raw water flow is divided into two crop water flows and condensed water flow. Is also referred to as thickening flow, salty water or derailment.
Reasons for using industrial desalination machine
One of the biggest restrictions all over the world is the lack of freshwater, which has caused many problems in the industry and daily life of humans. These restrictions are not only in the supply of drinking water, but also in agriculture and the production of medicines and health and industry. In contrast, seawater is unusable due to its high volume of salt and minerals, which can be used in the nature cycle by sea desalination. Using the RO desalination machine allows up to 99.6% of the minerals in the water and eventually deliver the fresh and pure water as the output.
How to operate industrial desalination machine
In sweetening water with reverse osmosis, raw water (unregistered) is pumped into a chamber that has a semi -derived membrane (membrane), because only pure water can pass through the membrane. This causes almost pure water on one side of the membrane and concentrated water from impurities on the other. This external pressure is greater than the natural osmotic pressure, so the molecules are smaller than the pores of the membrane, while the larger molecules are unable to cross the membrane. It should be noted that the diameter of the pores of a membrane even from the diameter of a virus and bacteria It is also smaller. Larger molecules pass through the membrane and excrete. In general, the way the reverse osmosis works is as follows:
Salt water with high salts enters the machine
Used to transfer salty water to sweet pump
In the passion of salty water to the sweet, the semi -trawed membrane with very small pores and prevents minerals from passing into the freshwater section
After several times the desalination machine requires a filter and semi -permeable membrane in a variety of ways such as backwash and chemicals.

Equipment and tools of industrial desalination system
The process of transferring the water from the semi -permeable membrane and the removal of ions, minerals and contaminants requires pressure, which has the amount of pressure applied to the water due to the amount of contamination and other referrals. For this reason, control equipment is used in different parts of the device to eventually obtain water output by removing more than 98 % of minerals and 100 % of bacteria and viruses.

All kinds of industrial desalination machine
desalination can be divided into different groups depending on the type of use of them, as the type of membrane, capacity, pre -purification process, etc. are designed in different environments. Accordingly, the most common types of RO desalination are:
Agricultural desalination machine
Due to the geographical conditions of Iran and the desert most of its areas, water reform is needed for agriculture in central and eastern cities as well as the south. For this reason, in most mechanized fields, desalination machines are used to reduce the amount of minerals in the water. The entry of high salts into the agricultural lands gradually leads to soil erosion and greatly reduces the quality of crops.
Marine desalination machine
pointed to seawater treatment and eliminating minerals and reducing salinity and using them in agriculture and other industries. The very important issue in this equipment is the high importance of pre -treatment for the removal of aquaculture and other contaminants in the sea. For this reason, other equipment such as junk and a variety of filters and settings is used next to the RO device. In addition, the type of filter and membranes used in this equipment must be capable of removing a large volume of minerals. In order to increase the efficiency of these equipment, shorter timeframes are considered to revive membranes.
