The battle for environmental protection is still raging. I hope that this year's haze control will be effective. Water is not only the source of life, but also extremely important to human beings, and the pollution is so severe. Long-term drinking of poor water quality can lead to poor physical...

1 What are the pretreatment equipment you know? A: Pretreatment equipment includes: mechanical filter, high-efficiency fiber filter, activated carbon filter, precision filter, ultrafiltration, microfiltration, sodium ion softener, iron and manganese removal filter, dosing device, raw water tank, ae...

The pore size of RO reverse osmosis membrane is as small as nanometer (1 nanometer=10 * - 9 meters). Under certain pressure, water molecules can pass through the RO membrane, while inorganic salts, heavy metal ions, organics, colloids, bacteria, viruses and other impurities in the source water canno...

The reverse osmosis scale inhibitor is generally added to the security filter of the reverse osmosis system, that is, before the precision filter. It is added to the dosing device and added to the pipeline of the reverse osmosis equipment through the metering pump. The reverse osmosis scale inhibito...

The internal and external surface anti-corrosion and coating of chemical water treatment system equipment, pipes, valves and accessories can meet the requirements of corresponding media and surrounding environmental conditions. The reverse osmosis device is controlled by PLC, including the normal o...

The reverse osmosis system includes three parts: raw water pretreatment, reverse osmosis device and post-treatment. RO system has its specific requirements for raw water pretreatment. Due to the wide variety of raw water and its very complex composition, according to the requirements of the raw wate...

What is the difference between pure water, purified water and ultrapure water? 1. The difficulty of manufacturing is different. At present, the pure water used in the market is basically prepared by reverse osmosis, distillation and other methods. Purified water is pharmaceutical water prepared by...

Comparison of nanofiltration membrane, reverse osmosis membrane and ultrafiltration membrane Nanofiltration membrane: capable of intercepting substances of nanometer scale (0.001 μ m). The operating range of nanofiltration membrane is between ultrafiltration and reverse osmosis. Its molecular we...
