As one of the industrial wastewater, coating wastewater mainly comes from pre degreasing, degreasing, surface conditioning, phosphating, passivation and other pre-treatment processes of the vehicle body. Especially, the composition of electrophoresis wastewater and painting wastewater is complex, wi...

With climate change and global population growth, freshwater resources are becoming increasingly scarce, thereby increasing the demand for wastewater regeneration. According to incomplete statistics, there are approximately 4000 sewage treatment plants that have been built and operated nationwide, w...

As far as reverse osmosis water treatment equipment is concerned, its core is reverse osmosis technology, which is mainly used to achieve the purpose of separation, extraction, purification and concentration according to the different osmotic pressure of various materials. Although the reverse osmos...

Water treatment processes in steel plants mainly include desalted water treatment, cooling water treatment, make-up water treatment, etc. In actual production processes, circulating cooling water systems, make-up water systems, and other auxiliary process measures are generally adopted.

Hongjie Water, March 26: Engineers at the University of British Columbia have developed a new water treatment method that can safely and efficiently remove "permanent chemicals" 【PFAS】 from drinking water - and is permanently effective. The full English name of PFAS is per/polyfluoroalkyl derivativ...

Working principle of reverse osmosis dosing 01 Various raw water contains certain concentrations of suspended solids and soluble substances. The suspended solids are mainly inorganic salts, colloids, and biological particles such as microorganisms and algae. Soluble substances mainly include solub...

01 What is EDI? The full English name for EDI is electrode ionization, which translates into electrodesalting, also known as electrodeionization, or packed bed electrodialysis. Electrodeionization technology combines ion exchange and electrodialysis. It is a desalination technology developed on t...

Control Measures for Inlet Water Quality Index of EDI Ultrapure Water System The control measures for the inflow water quality indicators of EDI ultra-pure water system are as follows: 1. Control of inlet water conductivity. Control the conductivity during the pre-treatment process so that the EDI...
