The system uses a simplified wet process that’s easy to maintain, with parts readily available locally—reducing downtime and repair costs.

While this article focuses on water-treated PCB recycling equipment, it’s important to understand how it compares to dry process systems—another popular option in the industry. Both have their strengths, and the right choice depends on your specific needs, including throughput, budget, and environmental goals.

Water Process Equipment: The Pros and Cons

Pros:

• Higher metal purity: Water-based systems typically achieve higher purity levels (99%+ for many metals) due to the precision of liquid separation.
• Better for complex PCBs: They handle mixed materials (plastics, metals, ceramics) more effectively than dry processes, which can struggle with fine particles.
• Lower dust emissions: Since the process uses water, there’s less airborne dust, reducing the need for extensive air filtration (though an air pollution control system is still recommended).

Cons:

• Higher water usage: While modern systems recycle water, they still require more initial water than dry processes.
• Wastewater treatment needs: Even with recycling, some wastewater may need treatment before discharge, adding to operational costs.
• Slower throughput: Wet processes can be slightly slower than dry systems, though advanced models (like GreenTech’s WCBR-2000W) are closing this gap.

Dry Process Equipment: A Quick Comparison

Dry systems use air separation, magnets, and electrostatic charges to separate metals from non-metals. They’re faster and use less water, making them popular for high-throughput operations. However, they often struggle with fine metal particles and mixed materials, leading to lower purity. For recyclers focused on volume over purity (or handling simpler PCBs), dry processes may be preferable. But for those targeting high-value metals (like gold and silver) where purity is critical, water-treated systems are the better choice.

Many top Asian suppliers, like Taiwan’s Recycling Machinery Corp., now offer hybrid systems that combine dry pre-shredding with wet separation, blending the best of both worlds. This flexibility is a testament to the industry’s commitment to innovation.
