RO is the abbreviation of Reverse Osmosis membrane in English, which means reverse osmosis membrane in Chinese. The general flow pattern of water is from low concentration to high concentration. Once water is pressurized, it will flow from high concentration to low concentration, which is known as the reverse osmosis membrane principle: Because the pore size of RO reverse osmosis membranes is five millionths of a human hair (0.0001 micrometers), it is generally invisible to the naked eye. Viruses are 5,000 times larger than it. Therefore, only water molecules and some mineral ions beneficial to the human body can pass through, while other impurities and heavy metals are discharged through the wastewater pipe. All seawater desalination processes and the recycling and treatment of astronauts' wastewater adopt this method. Therefore, RO membranes are also known as "high-tech outside the body".

Details >How to prevent Perlite resin from being contaminated by organic substances
How to prevent Perlite resin from being contaminated by organic substances? 1. After long-term use, Perlite mixed bed ion exchange resin may be contaminated by some substances, such as iron contamination and organic matter contamination. Before taking measures to deal with it, an analysis should be conducted and appropriate methods can be adopted for treatment. The causes and phenomena of organic contamination of Polite cation exchange resin: When there are oils, humic acid and other organic substances in the water, it is very easy to form an oil film on the surface of the resin, blocking the micropores of the resin and sealing the active exchange groups, thereby seriously affecting the performance of the resin. When the Polite cation exchange resin is contaminated by organic substances, it will show a darkening and blackening of color, a decrease in resin density and a significant drop in exchange capacity, leading to resin stratification

Details >Common problem analysis and solutions for the dosing system of metering pumps
During the long-term operation of the metering pump dosing system, some faults are inevitable. After a malfunction occurs, how to make correct judgments and analyses and confirm the cause of the malfunction is part of the daily work of equipment users and maintenance personnel. Here, the editor has collected and sorted out some common fault phenomena and possible causes related to metering pumps, which can be used for reference and learning by everyone!
Details >Drinking water and health: Their Impact on the Human Body
Water is the source of life. Life originated from water. Water is an important component of all cells and life tissues and an essential material basis for all life in nature. All kinds of physiological functions of human beings are carried out or realized with the participation of water. A man can go a day without food, but not a day without water. A person's longevity and health are closely related to the quality of their daily drinking water and their drinking habits.

Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.
The non-negative pressure water supply equipment can be directly connected to the municipal water supply network, making full use of the residual pressure of the original network for superimposed water supply. Fully enclosed operation does not require the construction of a domestic water tank, eliminating secondary pollution. Intelligent variable frequency voltage stabilization, energy-saving, quiet and easy installation, it is the preferred equipment for secondary water supply in high-rise residential buildings and commercial buildings.
Constant pressure water supply equipment is widely used in central air conditioning, floor heating, industrial closed-loop water circulation, and boiler systems. It integrates automatic pressure stabilization, automatic water replenishment, automatic exhaust, pressure relief and buffering functions. It stabilizes the pressure in the pipeline network, eliminates abnormal sounds caused by air blockage, and prevents damage from negative pressure and water shortage in the pipeline. It is an essential supporting equipment for HVAC and circulating water systems.
