Copper Powder Recovery Water Treatment System

Copper powder recovery water treatment system is widely used in the copper powder recovery and discharge water purification and recycling treatment plants in the printed circuit board production process.

The copper content in recycled water decreases, and the recycled copper powder increases; this can reduce pollution, reduce the production cost of circuit boards, and improve competitiveness.

Copper Powder Recovery Water Treatment System

Copper powder recovery water treatment system is also called the copper powder recovery machine and the grinding plate regeneration system. It is a device that can recover recyclable water. It mainly recovers and treats the discharge water generated by the circuit board grinding machine, the water washing machine, and the bottom of the sink to collect the copper powder and clean water in the discharge water to be recycled. The copper powder recovery machine can not only purify the wastewater, but also recover valuable copper resources at the same time, turning the waste problem into an economic opportunity.

The core of the copper powder recovery water treatment system is the filtration device, which uses advanced technologies such as membrane filtration or precipitation to separate copper particles from wastewater. It mainly includes pretreatment, chemical treatment, metal recovery, and filtration. Among them, the fully automatic filtration recovery machine has high efficiency, an accuracy range of 5-1500 microns, and can handle liquids with a viscosity of up to 800,000 centipoise. This set of equipment adopts an explosion-proof design to filter flammable and explosive liquids safely. It is usually used to recover and treat metallic dust pollution generated by the grinding process in PCB production. It increases the recovery of copper powder and circulating water and expands the scope of use of recycled water.

Process Of Copper Powder Recovery Water Treatment System

Working principle

It works by separating copper particles from water through physical and chemical processes. Wastewater containing dissolved copper ions is treated using specific reagents promoting the formation of insoluble copper compounds. These compounds then aggregate into larger particles that can be effectively removed from the water column.

Once formed, these aggregated particles rise to the surface through a flotation process facilitated by bubbles introduced into the treatment chamber. This floating sludge can be easily skimmed off for further processing or sold directly as industrial-grade copper powder. Copper powder is separated from water using processes such as centrifugation (spinning to separate solids) or electrolysis (applying an electric current to recover copper ions). Dense flocs will settle to the bottom of the clarifier, separating the solids from the treated water. The treated water may undergo additional treatment to ensure it meets regulatory standards for discharge or reuse.

process features

1. A fully automatic filter recovery machine, with fully automatic operation, high filtration accuracy, stable and reliable performance, is a good choice to replace traditional manual filters or use discarded types;

2. The most efficient choice of filter material filter, the liquid flows from the filter inlet, flows from top to bottom, and flows through the filter element surface to the outlet when the filter element surface;

3. When a certain amount of impurities are collected, the liquid containing a high concentration of impurities is discharged, and the residual liquid can be recycled or discharged;

4. It provides powerful and diverse customization options to meet the filtration requirements further and improve the filtration process and operation experience;

5. Modular multi-unit combination to meet the requirements of larger flow filtration; open door design, convenient to remove the filter residue;

6. Suitable for high-precision filtration, up to 5 microns, with a unique filter surface structure, smooth surface, and excellent scraping and cleaning effect;

7. The filter opening gap is uniform and consistent, which is a key component to achieving efficient and stable filtration. It also has excellent corrosion resistance.
