Working principle and composition of reverse osmosis equipment

Working principle of reverse osmosis equipment:

The reverse osmosis equipment passes the raw water through fine filters, granular activated carbon filters, compressed activated carbon filters, etc., and then pressurizes it through a pump, utilizing a pore size of 1/10000 μ M (equivalent to 1/6000 of the size of Escherichia coli and 1/300 of the virus) reverse osmosis membrane (RO membrane), so that the water with high concentration can be turned into the water with low concentration. At the same time, a large number of industrial pollutants, heavy metals, bacteria, viruses and other impuritiesmixed in the water can be isolated, so as to meet the physical and chemical indicators and health standards for drinking, and produce clean to pure water, It is the best choice for the human body to replenish high-quality water in a timely manner. Due to the fact that the water purity produced by RO reverse osmosis technology is currently the highest among all water production technologies mastered by humans, with a cleanliness of almost 100%, people call this water production machine a reverse osmosis pure water machine.

The reverse osmosis equipment applies membrane separation technology, which can effectively remove charged ions, inorganic compound, colloidal particles, bacteria and organic substances in water. It is the best equipment in the preparation of high-purity water, desalination of brackish water, and wastewater treatment processes. Widely used in fields such as electronics, medicine, food, textile, chemical, power generation, etc.

Composition of reverse osmosis equipment system:

Generally, it includes pre-treatment systems, reverse osmosis devices, post-treatment systems, cleaning systems, and electrical control systems.

Pretreatment system generally includes raw water pump, dosing device, quartz sand filter, activated carbon filter, precision filter, etc. Its main function is to reduce the pollution index of raw water and other impurities such as residual chlorine, in order to meet the inflow requirements of reverse osmosis. The equipment configuration of the pre-treatment system should be determined based on the specific situation of the raw water.

The reverse osmosis device mainly consists of multi-stage high-pressure pumps, reverse osmosis membrane components, membrane shells (pressure vessels), brackets, etc. Its main function is to remove impurities from the water and ensure that the effluent meets the usage requirements.

The post-treatment system is an added configuration when reverse osmosis cannot meet the effluent requirements. Mainly including one or more equipment such as anion bed, cation bed, mixed bed, sterilization, ultrafiltration, EDI, etc. The post-treatment system can better improve the water quality of the reverse osmosis effluent to meet the usage requirements.

The cleaning system mainly consists of a cleaning water tank, a cleaning water pump, and a precision filter. When the effluent indicators of the reverse osmosis system cannot meet the requirements due to contamination, it is necessary to clean the reverse osmosis system to restore its effectiveness.

The electrical control system is used to control the normal operation of the entire reverse osmosis system. Including instrument panel, control panel, various electrical protection, electrical control cabinet, etc.
