Reverse Osmosis Systems

Reverse Osmosis Systems

Reverse osmosis systems enable the demineralization of water by removing minerals and ions in the water due to the filtration ability of 2 Angstrom size. Reverse osmosis units have a special place in the manufacturing industry where industrial plants that need purified water to meet the process water needs. Reverse osmosis systems are widely used in the demineralization of wells with high salinity and the desalination of marine waters into fresh water. During the reverse osmosis process, the pressure of the water is increased to allow pure water to pass through the membrane pores. Ions, which can not pass through the membrane elements, are conducted in concentrate water phase. In order to extend the lifetime of the reverse osmosis membrane elements, it is necessary to use a number of pre-treatment units. The pre-treatment units before RO are designed according to raw water analysis data. Before designing reverse osmosis systems and pretreatment units, raw water is analyzed to determine pH, hardness, conductivity, TDS, TSS, chlorine, silica, iron, manganese, SDI (Silt density Index) measurements are made. RO system design is made according to these analysis parameters’ results. Preliminary treatment processes applied before reverse osmosis systems include chlorine dosing system, ultrafiltration system, multimedia sand filter, activated carbon filter, iron manganese removal filter, SMBS dosage unit, acid dosage and pH adjustment system, antiscalant dosage system, micro filtration systems etc.
