Problems solved by technology

Refractory wastewater has become a difficulty in wastewater treatment and the focus of research at home and abroad. The early commonly used organic wastewater treatment technologies at home and abroad are generally non-destructive treatment technologies, such as chemical coagulation, air flotation, physical adsorption, membrane Filtration, etc., just transfer the organic matter from the liquid phase to the solid phase, and the problems of secondary pollution and regeneration of adsorbents and coagulants have not been reasonably solved.

However, membrane fouling is the biggest defect of membrane separation technology. Membrane fouling causes significant changes in membrane water treatment effect and energy consumption over time, which restricts the further development of membrane separation technology.
