The two stage reverse osmosis system is a highly efficient water treatment equipment. It removes impurities in water through a two-stage reverse osmosis process to obtain high-purity water. The secondary reverse osmosis system is mainly composed of a pretreatment system, a two-stage RO (Reverse Osmosis) device, a cleaning system, an intermediate water tank, and corresponding pipes, valves, pumps and other auxiliary equipment. Among them, the two-stage RO device is the core part of the system, and the deep purification of water is achieved through the filtering effect of the two-stage reverse osmosis membrane.
Two Stage Reverse Osmosis System DescriptionThe two-stage reverse osmosis device mainly includes a two-stage RO (Reverse Osmosis) device, a cleaning system and an intermediate water tank. The two-stage RO device is the core part. Through the filtering effect of the two-stage reverse osmosis membrane, it can effectively remove dissolved salts, organic matter, colloids, macromolecular substances and particulate matter that has not been removed by pretreatment in the water. The cleaning system is used to regularly clean the RO membrane to prevent scaling and fouling, and ensure the stable operation of the equipment. The intermediate water tank is used to store RO produced water, adjust the water volume, and make the system operation more flexible.
Pretreatment: The raw water first passes through the pretreatment system, including multi-media filters, activated carbon filters, water softeners, security filters, etc., to remove suspended solids, color, odor, residual chlorine, rust and other pollutants in the water to protect the service life of the reverse osmosis membrane.
Primary reverse osmosis: The pretreated water enters the primary reverse osmosis system and is pressurized by a high-pressure pump, so that water molecules pass through the reverse osmosis membrane under pressure, while impurities, ions, etc. in the water are retained on one side of the membrane and discharged with concentrated water. The water produced by the primary reverse osmosis will be used as the inlet water for the secondary reverse osmosis.
Secondary reverse osmosis: The water produced by the primary reverse osmosis enters the secondary reverse osmosis system for further filtration and purification. The secondary reverse osmosis membrane has a smaller pore size and a stronger ability to retain impurities, so higher purity water can be obtained.
Two Stage Reverse Osmosis System DetailEfficient removal of impurities: The secondary reverse osmosis device can effectively remove impurities such as dissolved salts, organic matter, colloids, particles, bacteria, viruses, etc. in the water, and the effluent water quality is high.
Low energy consumption: The separation process of the reverse osmosis method does not require heating and there is no phase change, so the energy consumption is low.
Small equipment size: Compared with other desalination equipment, the secondary reverse osmosis device has a smaller equipment size and occupies less area.
Simple operation: The equipment has a high degree of automation, simple and convenient operation, and easy maintenance.
Wide range of applications: widely used in electronics, medicine, food, chemical industry and other industrial fields as well as seawater desalination, wastewater treatment and other fields.
