Since the 20th century, the rapid development of pharmaceutical industry has brought a leap to human civilization and solved many plague problems. At the same time, the wastewater discharged from its production process has caused pollution to the environment, affecting human life as well as health. What Is Medical Wastewater? Hospital wastewater contains three major […]
Groundwater can be developed and utilized as a water source for domestic water, industrial water and farmland irrigation. Moreover, groundwater has the advantages of stable water supply and less pollution. It is an essential resource for human life and development. However, most groundwater contains excessive levels of iron and manganese, which can affect the color, […]
Brackish water is when the chloride in a water source exceeds the normal range. Brackish water is formed mainly due to excessive water use, or when the water level is below sea level due to changes in the earth’s crust, when seawater is backed up, or when surface water flows through saline areas. Since chloride […]
Surface water refers to the water that exists on the surface of the earth’s crust and is exposed to the atmosphere. It is one of the important sources of water for human life and the main component of water resources in various countries. But surface water contains a variety of impurities, including algae, sediment, suspended […]
Coal mine water refers to all the water that penetrates into the underground mining space during the coal mining process, and sometimes also contains a small amount of infiltrated surface water. Coal mine water treatment technologies mainly include neutralization of acidic water, flocculation treatment to remove suspended particles, reverse osmosis to remove soluble salts and […]
What Is Reverse Osmosis Equipment? Reverse osmosis is a relatively advanced and energy-efficient membrane separation technology in the world today. It mainly uses the osmosis principle of the semi-permeable membrane, and applies a pressure to it in a certain way, which is opposite to the force of the natural osmosis direction, so that the water […]
With the continuous improvement of the level of global industrialization, freshwater resources are increasingly scarce, and the lack of water resources has led to slow global industrial development. Desalination has become an important option for coastal cities to solve such problems. Valves are widely used in seawater desalination plants. As important control components in various […]
The global water pollution situation is becoming more and more serious, and sewage treatment and other water treatment industries have received unprecedented attention. In the sewage treatment pipeline system, the valve plays a very important role in building the fluid conveying system and controlling the direction, flow, pressure, etc. of the fluid. It is convenient […]
Pneumatic accessories are industrial equipment used to realize industrial automation. There are positioners, limit switches, pneumatic reversing valves, air filters, etc. for your choice. Each pneumatic accessory has a different function. It is generally used with various types of pneumatic valves, which is convenient for remote control and industrial automation to improve the production efficiency […]
Mechanical vapor recompression is an industrial system for seawater desalination, metal processing plants, and food processing plants. It is used for waste & wastewater treatment, improving water resource utilization and waste treatment rate, and making our living environment more environmentally friendly. Since 2000, COVNA helped more than 500 wastewater treatment projects with automated valve solutions. […]
