Brackish water TDS range 3000 - 45000 ppm , according to the organic content can be divided into surface water and ground water . surface water we can reverse osmosis system mating with relative sterilization system , ground water we can direct use reverse osmosis system , if Iron and Manganese overpass the inlet condition of RO ,we need add Manganese sand filter for pretreatment system , here also include the specific inlet conditon of RO system for reference.
Raw water pump-- provide the pressure to silica sand filter/active carbon filter
Silica Sand filter-- get rid of turbidity, suspended matter, organic matter, colloid
Active Carbon filter--Remove the color, free chloride, organic matter, harmful matter and so on
Softener--reduce the hardness of water
Micron filter--prevent any deposition of large Particles, most of the bacteria, and viruses into the RO membrane, The accuracy is 5um, for holding back any large particulates such as large iron, dust, suspended matter, impurity.
RO system--RO system is the main part of pure water treatment plant. The RO membrane's desalt rate can reach as high as 99%, it is capable of removing over 99% of ions, bacteria, particles and 98% of organic.
High pressure pump-- Provide the high pressure to RO membrane(at least 2.0 Mpa).
RO series reverse osmosis device for electronics, electroplating,power plants, pharmaceutical, petroleu, chemical, food and beverage and printing industries to provide high quality water, reverse osmosis pure water technology is the most advanced, most economical, the most effective system of water technology, which is the use of ultra-thin film reverse osmosis membrane by water pressure, so that the water seepage from the high levels of salt to reverse the process of low salinity. Can remove most of the harmful substances, heavy metals, solids can be capacitive, only water molecules can only end through a reverse osmosis membrane water.
