RO Reverse osmosis device

Product description

Reverse Osmosis (RO) is a pressure-driven technology that separates the solute and the capacitant in the solution through a selective membrane, which can effectively remove dissolved salts, colloids, bacteria and organic matter from the water. Is a widely used pure water production process, with a high degree of automation, low energy consumption, no pollution, small footprint, water quality and stability (water quality to adapt to a large range) and strong organization and other advantages, widely used in electronics, pharmaceutical medicine, food and beverage, chemical industry, drinking pure water, boiler supply water, seawater desalination, material recycling and environmental protection industries. The combination of the CHRO system reverse osmosis device and ion exchange equipment (double bed and mixed bed) can produce better quality pure water, and the terminal outlet water conductivity can reach 0.05µs/cm(25℃).

First, the working principle

A selective membrane that allows one or more components of a solution to pass through while others do not is called a semi-permeable membrane. When the pure solvent and the solution (or the solution of different concentrations) are separated by a semi-permeable membrane, the pure solvent has a spontaneous flow through the membrane to the solution phase (or from a low concentration solution to a high concentration solution), this phenomenon is called osmosis. If an external pressure is applied to one side (or to the concentrated solution side) to impede the flow of the solvent, the rate of penetration will decrease when the pressure is applied to stop the penetration completely. The tendency of penetration is balanced by the applied pressure. This equilibrium pressure is called osmotic pressure. Osmotic pressure is a property of the solution, independent of the membrane. If the pressure on the solution side is further increased, the solvent reverse osmosis flow is caused, this phenomenon is conventionally called "reverse (reverse) osmosis". In short, Reverse Osmosis (RO) is a pressure-driven technology that separates the solute from the capacitor in a solution by selectively passing through a membrane.

Second, equipment performance

CHRO system reverse osmosis device from the design and material selection and other aspects of strict control, product performance has reached the level of similar foreign products, technical performance in the country.

1, reverse osmosis membrane (RO membrane) from the United States (Hyde, Dow, etc.) introduced, and strictly abide by the membrane manufacturers related membrane system design guidelines, good water quality and long service life.

2, high pressure pump selection of well-known brand multi-stage centrifugal pump, with stable operation, low noise, high efficiency and long service life characteristics, automatic control pump start and stop and low pressure switch protection to ensure that the pump will not be damaged because of water supply stop.

3. The electrical components are selected from well-known manufacturers to ensure the continuous and stable operation of the entire device.

4, the perfect pre-treatment system is equipped with a precision filter to protect the high pressure pump and RO film from external damage.

5, the production of water and concentrated water set flowmeters to monitor and adjust the operation of the water production and system recovery, in the end of the water set up online conductance or resistance meter continuous monitoring of product water quality.

6, automatic regular cleaning system regularly clean the RO film, slow down the speed of film pollution and extend the service life of the film, in the water inlet and drainage measurement set pressure gauge to continuously monitor the pressure difference of each section, indicating the appropriate need for forced cleaning.
