Polarity reverse rectifier in water treatment industry, also known as electrolysis for metal recovery, is a process used to recover metals from various sources, including electronic waste and other scrap materials.

Polarity reversing" in water treatment refers to the process of periodically switching the electrical current polarity in an electrochemical water treatment system, like electrocoagulation, to prevent the build-up of deposits on the electrodes, commonly known as "fouling," by periodically removing accumulated particles from the electrode surface, thus improving the efficiency of the treatment process.The polarity reversal typically happens several times per hour to maintain effective cleaning.

APPLICATIONS

E-Waste Recycling

Reverse power supply is particularly useful in recovering precious metals like gold, silver, and palladium from electronic components.

Electrocoagulation

By periodically reversing the polarity, leading to better treatment performance over time.

Electrodialysis

Remove dissolved ions from water using an electric field and semipermeable membranes. By reversing the polarity, the ions that have accumulated on the membrane surface are pulled away, preventing buildup and extending the lifespan of the membrane. 

Product Advantages

1.Efficiency

This method can efficiently recover metals with high purity.

2.Environmental Impact

It can reduce the amount of waste sent to land-fills and minimize the need for mining new metals.

3.Safety and Environmental Concerns

The chemicals used in the electrolyte and the handling of electronic waste need to be managed carefully to prevent environmental contamination.
