Product Introduction
In the PCB, TFT-LCD, or semiconductor electronic manufacturing factory, wet processes such as electroplating, wet etching, or roughening are widely adopted for copper interconnect formation. Therefore, various types of copper-containing wastewater will be produced. Conventionally, chemical precipitation by adding wastewater treatment chemical, and forming copper sludge is the most extensively employed strategy for Cu wastewater treatment. However, a significant amount of copper sludge should be outsourced as hazardous waste, and the Cu ions within the wastewater can hardly be recycled.
The Recocell® electrowinning system can effectively recover Cu metal (purity>99%) from various copper containing wastewater in the electronic manufacturers. The recovered product is metallic copper, and has no risk for environment since it has no pollutant disposal issue. Furthermore, it can easily be put into the supplier chain as raw material locally, and satisfy the target of circular economy. During the electrowinning process, there is no secondary waste produced during the process, and will not add the secondary pollution or burden owing to the refinery procedures.
The service team of Waste Recovery Technology can provide customized design based on the factory’s wastewater characteristics, and match with the existing wastewater treatment module to create the highest benefit. With multiple type of integrated module such as solvent extraction, ion-exchange tower… etc. We are able to provide the best solution for in-house Cu wastewater treatment.
Recocell® electrowinning system can also be applied in different type of metal such as nickel, cobalt…etc. We are able to treat electroless nickel, electroplating nickel/cobalt wastewater.
Waste Recovery Technology company’s Recocell® has following advantages:
- Tubular design, able to operate with high current density and high output.
- Centralized gas evacuation system, the electrowinning environment has no acidic gas issue.
- The current distribution and efficiency re high, very low hydrogen gas evolution side reaction.
- Separatable cathode design, and easy to withdraw copper by crane.
- Module design allow the possibility to add electrowinning cell depending on the factory’s demand.
- High automation control panel and complete safety monitor system.
