Introduction: Planning dimension upgrading and strategic iteration in the water treatment industry This year is a year in which environmental protection enterprises are extremely eager for development, and it is also a year full of variables for the entire industry. Recently, the Ministry of Ecology...

With the improvement of automation level in various industries, the requirements for technology are becoming higher and higher, so stricter requirements are put forward for the selection of field instruments. Correct and reasonable field instrument selection can not only reduce the probability of fi...

The service life of EDI membrane stack is limited. Whether it is imported or domestic, we all know that under normal use, the service life of EDI is approximately 3-5 years. In the process of EDI maintenance, cases of failure within half a year or one year are often received, which are not limited t...

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...

Hydrochloric acid and sulfuric acid can be added to the influent water to reduce the pH. Sulfuric acid is more commonly used than hydrochloric acid because it is cheap, does not emit smoke and corrodes surrounding metal components, and the membrane has a higher removal rate of sulfate ions than chlo...

1. What is COD (chemical oxygen demand)? Chemical oxygen demand (COD) refers to the amount of oxygen required by the oxidizable substances in the wastewater when they are oxidized by chemical oxidants, in mg/L of oxygen. It is the most commonly used method to determine the content of organic matter...

Membrane separation technology is a high and new technology that has risen rapidly in the past 40 years.
