PCB Wastewater Treatment Facilities
Different processes at printed circuit board (PCB) production plants generate various types of wastewater containing resist, developing and stripping solutions, copper sulfate plating, copper chloride etchants and/or other substance. Therefore, advanced treatment technology and top-of-the-line equipment are necessary to treat these wastewaters.
NCE can build optimized treatment equipment that meets the needs of a wide range of PCB production plants.
Components of PCB Wastewater Treatment Facilities
The following equipment is used to treat wastewater from PCB production processes.
This equipment is used in inorganic wastewater treatment.
Heavy metals, suspended solids (SS), colloidal substances and other substances contained in the wastewater are neutralized and then quickly separated and precipitated out.
Rapid Filtration Towers
This equipment provides supernatant filtration and removal of solid matter, suspended particles and so forth via rapid filtration.
The upper filter media can efficiently remove everything from large particles to small suspended solids (SS).
Activated Carbon Adsorption Towers
Even after passing wastewater through flocculation and sedimentation treatment and filtering it, trace colors, odors and quantities of organic compounds will remain.
Activated carbon adsorption towers can be used for secondary treatment. BOD and COD reduction are also possible.
Fully Automated Compact Filter Presses
This fully automated compact filter press equipment removes water from sludge. It is designed to handle difficult-to-filter slurry, and the resulting filter cake can be reliable removed using a removal device.
