Discussion on the characteristics of various filter media in filter tanks
2024-01-22
As the core treatment unit of a water plant, filter media plays a crucial role in the filtration process. The commonly used filter media include quartz sand, granular activated carbon, garnet, titanium iron ore, ceramic particles, etc. How to choose a suitable filter media depends on the water quality of the raw water. Below, based on experience, we will discuss the principles and characteristics of various filter media.

What is advanced oxidation technology?
2024-01-12
Advanced oxidation technology, also known as deep oxidation technology, is based on the use of electricity, light irradiation, catalysts, and sometimes combined with oxidants to produce highly active free radicals (such as HO) in the reaction. Through the addition, substitution, electron transfer, and bond breaking between free radicals and organic compounds, large molecules of difficult to degrade organic matter in water are oxidized and degraded into low toxic or non-toxic small molecules, and even directly degraded into CO2 and H2O, The current advanced oxidation technologies for near complete mineralization mainly include chemical oxidation, electrochemical oxidation, wet oxidation, supercritical water oxidation, and photocatalytic oxidation.

The Future Development Trends of High Concentration Wastewater Treatment
2024-01-10
The problem of treating high concentration organic wastewater is widely recognized as a difficult problem in current world sewage treatment. The so-called high concentration wastewater refers to wastewater with high concentration, high salt content, and high difficulty in degradation. The composition of water quality is complex, with high organic matter content.
