Copper Powder Recycling Water Treatment System

During the manufacturing process of PCB boards, the substrate needs to be copper-immersed, copper-coated and copper-ground, and in the process of copper-ground boards, the conventional equipment will discharge the wastewater generated from the grinding of boards (which contains a large amount of copper powder) directly into the sewage tank, and will consume a large amount of water for rinsing. If not treated, this copper-containing wastewater will not only pollute the environment, but also cause a waste of resources. Therefore, in the PCB (printed circuit board) manufacturing industry, copper powder recovery water treatment system is particularly important.
Copper Powder Recycling Water Treatment System
The copper powder recycling water treatment system is a copper-containing wastewater treatment equipment, which particularly relates to a kind of equipment for treating copper-containing wastewater in the PCB board manufacturing grinding process.

Copper Powder Recycling Water Treatment System Process

Wastewater collection
The wastewater containing copper powder is collected centrally through pipes or tanks.
Solid-liquid separation
Use precipitation or filtration to separate copper powder from wastewater, commonly used methods are:
Gravitational settling: Use the property of copper powder being heavier than water to make the copper powder precipitate naturally.
Filtration: Use various filters, filter cloths, or cartridges to filter out the copper powder.
Automatic filter recovery machines and recoiling-type self-cleaning water filters are different, filter are not only used for water filtration, more widely used in solvent, acid lye, polymer, paint, and other viscous material self-cleaning filtration, higher efficiency, accuracy range of 5-1500 micron, can deal with a viscosity up to 800,000 cm of liquid, Applied in water treatment, petrochemical, metallurgy, electric power, fine chemical industry, paint, ink, paper, food and beverage, pharmaceutical, metal processing and other industries.

Chemical treatment
If copper ions are dissolved in the water, it is usually necessary to add chemicals, such as flocculants or reducing agents, so that the copper ions are converted into insoluble copper compounds to precipitate.

Dewatering
The recovered copper powder is dewatered for subsequent storage or reprocessing.

Wastewater purification
The treated water undergoes further purification, such as activated carbon adsorption, membrane filtration, and other processes, to remove other impurities and meet discharge standards or reuse requirements.

Water quality testing and recycling
The treated water is tested and qualified for recycling or discharge.
Copper Powder Recycling Water Treatment System Features
Automatic filter recovery machine, automatic operation, high filtration accuracy, stable and reliable performance, is to replace the traditional manual filter or use the abandoned type.
Filter material filter benefit selection, liquid from the filter inlet into, flow from top to bottom, through the filter element surface flow to the outlet when the filter surface.
When a certain amount of impurities are collected, the liquid containing a high concentration of impurities is discharged and the residual liquid can be recovered or discharged.

Such systems are important for reducing production costs and environmental impact in the PCB industry. If you need more specific technical parameters or system design solutions, they can be customized according to production scale and specific needs.
