A collection of Resources, News and Technologies from the Water and Wastewater Treatment Industry

As industrial development surges forward, the rational use and protection of water resources have become increasingly critical. With stricter discharge regulations for industrial wastewater, Zero Liquid Discharge (ZLD) technologies are emerging as a "golden key" to tackling pollution challenges thanks to their environmental and resource recovery benefits.

As global water resources become increasingly strained and environmental regulations grow more stringent, traditional wastewater treatment processes are falling short. Challenges such as low efficiency, large land requirements, and inconsistent effluent quality are driving the search for more effective alternatives. That’s where Membrane Bioreactor (MBR) technology steps in.

This article presents a comprehensive overview of electrocatalytic reduction technology in wastewater treatment, covering its fundamental principles, core equipment, and practical applications. It focuses on key areas such as electrochemical nitrate reduction, treatment of heavy metal wastewater, green oxidation through activated molecular oxygen, and its integration into advanced wastewater treatment processes.

In the field of environmental protection, Zero Liquid Discharge (ZLD) technology has become a symbol of innovation and strength, drawing widespread attention.

The electroplating industry generates significant volumes of wastewater containing hazardous heavy metals such as hexavalent chromium, nickel, and zinc. Traditional treatment methods often struggle to achieve complete resource recovery and zero liquid discharge (ZLD).

COD in wastewater, short for Chemical Oxygen Demand, is one of the most important indicators of organic pollution in both domestic and industrial effluents. But how is this pollution removed efficiently and sustainably? The answer lies in nature’s tiniest engineers: microorganisms.
