Beta and omega series reverse osmosis systems are systems used to purify high concentration water with chemical salts by 90- 99% to obtain low concentration water close to pure water. The working principle of the reverse osmosis process is realized through membranes. Water is forced to pass through the pores on the membranes under high pressure. During this process, while water molecules and some inorganic molecules can pass through these pores, most of the substances in the water cannot pass through these pores and are thrown out as concentrated water. The semi-permeable membrane is purified from organic and inorganic substances, salts, heavy metals, viruses and bacteria in the dissolved state in the water by passing only pure water. In the World Health Organization (WHO) drinking water standard, as in the EPA (Environmental Protection Agency of USA), the highest TDS allowed is 500 ppm (mg/lt). Achieving this quality in a brine treatment RO system depends on the inlet water and the system conditions to be selected accordingly.
