For this purpose, a pressure higher than the osmotic pressure and a semi-permeable membrane that limits the passage of dissolved ionic substances is needed. In the reverse osmosis process, clean water and pure water can be obtained using the appropriate pressure and membrane. Reverse osmosis technology is the most sensitive membrane filtration technology known. In this process, a stable rejection of 99% and minimum 96% desalination is achieved.
Membrane fouling is one of the most common problems in reverse osmosis systems. The membrane surface is covered with a layer formed as a result of the crystallization of chemical salts such as sulphate, carbonate and silica. These salts reduce the production efficiency by blocking the pores and channels of the membrane. Membrane clogging can be solved by acid washing. The pH values of the raw water are important in the formation of lime in the membranes. At high pH values, there is a high risk of membrane clogging and calcification. Proper selection and correct operation of pre-treatment equipment is important in order to prevent premature clogging of the membrane and reduce treatment efficiency.
Reverse Osmosis Using Areas
Reverse osmosis water treatment systems have a wide range of uses such as hemodialysis treatments, sterilization water treatment, brackish and well water treatment, industrial process water preparation, drinking water production, boiler feed water preparation, demineralization, deionization.
