The primary reverse osmosis system, also known as single-stage reverse osmosis, is a membrane separation operation that uses pressure difference as a driving force to separate solvents from solutions.
First Stage Reverse Osmosis System DescriptionPretreatment: The raw water first passes through the pretreatment system, including quartz sand filters, activated carbon filters, precision filters, etc., to remove large particle impurities, suspended matter, organic matter, etc. in the water to ensure the smooth progress of subsequent treatment.
Pressurization: The pretreated water is pressurized by a high-pressure pump to increase the water pressure to meet the working pressure requirements of the reverse osmosis membrane.
Reverse osmosis filtration: The pressurized water enters the reverse osmosis membrane assembly and uses a reverse osmosis membrane (Ro membrane) with a pore size of 1/10000μm (equivalent to 1/6000 of the size of E. coli and 1/300 of the virus) to turn higher concentration water into low concentration water, while isolating all impurities such as pollutants, heavy metals, bacteria, viruses, etc. that are mixed into the water.
Outlet water: The water filtered through the reverse osmosis membrane is pure water, and its conductivity can be guaranteed to be at a low level. For example, when the water temperature is around 25°C, the outlet water conductivity can be guaranteed to be within 10us/cm, and the desalination rate of the reverse osmosis host is above 99%.
First Stage Reverse Osmosis System DetailLow cost: Due to its relatively simple process flow and equipment configuration, the cost of a primary reverse osmosis system is usually low.
Easy operation: The operation and maintenance of the equipment are relatively simple, suitable for users with low technical requirements.
Wide range of applications: It can meet the needs of general industrial applications or occasions where water quality requirements are not too high.
Limited filtration effect: Although it can remove most impurities, it may not achieve the ideal filtration effect for some high-concentration salt water or special water quality.
In summary, the primary reverse osmosis system is an efficient and economical water treatment equipment, which is widely used in various fields that require high-purity water. When choosing, it is necessary to make a reasonable choice based on the specific application scenario and water quality requirements.
