3000L Per Hour SS304 Brackish Water Treatment Plant For Domestic Water

Brackish Water Treatment Plant

Basic principle and characteristics of reverse osmosis method through sex with an alternative film a container can be divided into two and a half, on both sides of the membrane in pure water and salt water respectively, at the same time make the membrane on both sides of the liquid level as high as brine side happens in a certain time of liquid level on the rise, and a decline in pure water side of the liquid surface, this is because the water molecules through a semipermeable membrane to brine lateral migration as a result, this phenomenon is called osmosis.A membrane that has selective transmittance to water or solution is called a semi-permeable membrane.If proper pressure is applied to one side of the concentrated solution, the infiltration can be stopped.The pressure at which the penetration of a dilute solution into a concentrated solution ceases is called the osmotic pressure.Reverse osmosis is to add a higher pressure than natural osmosis on one side of the concentrated solution, reverse the direction of natural osmosis, the ions in the solution to the other side of the semi-permeable membrane, which is contrary to the normal osmosis process in nature, so it is called "reverse osmosis", this device is called reverse osmosis device.The reverse osmosis method can remove more than 90 % dissolved salts and more than 99 % colloidal microorganisms and organic matter from the water.Compared with other water treatment methods, it has the advantages of no phase change, normal temperature operation, simple equipment, high efficiency, less occupation, convenient operation, less energy consumption, wide adaptability, high automation and good effluent quality.In particular, the reverse osmosis device for purifying brackywater powered by wind and solar energy is an economical and reliable way to solve the problem of people's domestic water in areas without electricity and short of conventional energy.Reverse osmosis desalination is not only suitable for seawater desalination, but also for brackish water desalination.Among the existing desalination methods, the reverse osmosis desalination method is the most economical, and it has even surpassed the electrodialysis desalination method.Because the driving force of the reverse osmosis process is pressure, there is no phase change in the process, and the membrane only plays the role of "screening", so the energy consumption required for the reverse osmosis separation process is relatively low.Among the existing seawater and brackish water desalination, reverse osmosis method is the most energy efficient.Reverse osmosis membrane separation is characterized by its "broad spectrum" separation, that is, it can not only remove all kinds of ions in the water, but also can get rid of particles larger than ions, such as most of the organic matter, colloids, viruses, bacteria, suspended solids, so reverse osmosis separation method is also known as broad spectrum separation method.
