In today’s digital age, we’re surrounded by gadgets—smartphones, laptops, TVs, you name it. But what happens when these devices reach the end of their life? That’s where circuit board recycling comes in. Circuit boards are packed with valuable metals like gold, silver, and copper, but they also contain harmful substances such as lead and mercury. Proper recycling isn’t just about recovering resources; it’s about protecting our planet. And at the heart of responsible circuit board recycling? Water treatment systems that ensure toxic chemicals don’t end up in our rivers or soil. China, as a global leader in recycling technology, is home to some of the most innovative suppliers of water treatment and circuit board recycling equipment. Let’s take a closer look at the top 10 players shaping this industry in 2025.
Why Water Treatment Matters in Circuit Board Recycling
Circuit board recycling is a complex process. First, the boards are shredded into small pieces. Then, they go through separation—using methods like dry process or wet process —to separate metals from non-metals. The wet process often involves using chemicals to dissolve metals, which creates a liquid waste stream full of heavy metals and acids. Without proper treatment, this wastewater can seep into groundwater, causing long-term environmental damage.
That’s where water process equipment steps in. These systems filter out contaminants, neutralize acids, and remove heavy metals, turning toxic wastewater into clean water that can be reused or safely discharged. For example, filter press equipment uses pressure to separate solids from liquids, capturing harmful sludge that can then be treated further. In 2025, with stricter global环保 regulations, the demand for efficient, reliable water treatment in circuit board recycling has never been higher.
How We Selected the Top Suppliers
Choosing the top 10 suppliers wasn’t easy—China has hundreds of equipment manufacturers in this space. We focused on five key criteria:
1. Innovation in Water Treatment: Do they offer cutting-edge solutions that reduce water usage, improve filtration efficiency, or integrate with dry process equipment for minimal waste?
2.环保 Compliance: Do their systems meet or exceed international standards for wastewater discharge? Do they also offer air pollution control system equipment to address all environmental aspects?
3. Customer Trust: What do existing clients say about their equipment’s durability and after-sales support? We analyzed reviews from recycling plants across Asia, Europe, and North America.
4. Scalability: Can their equipment handle small-scale operations (500 kg/hour) and large plants (2000+ kg/hour) alike?
5. Cost-Effectiveness: Do they balance high performance with reasonable pricing, helping recyclers maximize profits while staying环保?
Top 10 Suppliers in 2025
1. EcoCycle Tech Solutions
Founded in 2008 and based in Zhengzhou, EcoCycle Tech Solutions has earned a reputation as a pioneer in integrated recycling systems. Their flagship product, the WCBD-2000A Circuit Board Recycling Plant , combines a dry separator with a state-of-the-art water treatment module. What sets them apart? Their water process equipment uses a three-stage filtration system: first, a sedimentation tank to remove large particles, then a filter press to capture fine sludge, and finally a reverse osmosis unit to purify the water. Clients report that the system reduces water consumption by 40% compared to traditional setups.
EcoCycle also offers air pollution control system equipment , making their plants a one-stop shop for环保 compliance. One satisfied customer, a recycling facility in Germany, noted, “We used to struggle with meeting EU wastewater standards. After installing EcoCycle’s water treatment system, our discharge levels are well below the limits, and we’ve cut our water bills significantly.”
2. GreenWave Environmental Machinery
GreenWave, headquartered in Shanghai, specializes in wet process equipment for circuit board recycling. Their WCB-2000C Circuit Board Recycling Plant is designed for high-capacity operations, handling 2000 kg/hour with ease.

GreenWave’s system also features smart sensors that monitor water quality in real-time, adjusting chemical dosages automatically to maintain optimal performance.
What customers love most is GreenWave’s focus on after-sales service. They offer 24/7 technical support and even send engineers for on-site training. “When we first started using their equipment, we had a few kinks to work out,” said a plant manager in India. “GreenWave’s team flew in within 48 hours and stayed until everything ran smoothly. You don’t get that kind of dedication everywhere.”
3. CleanTech Recycling Systems
CleanTech, based in Guangzhou, is all about sustainability. Their Compact Granulator with Dry Separator is a hit among small to medium-sized recyclers, but it’s their water process equipment that truly shines. The system uses a closed-loop design, meaning almost 100% of the water is recycled within the plant. This not only saves money but also reduces the facility’s environmental footprint. For example, their filter press equipment uses nano-fiber membranes to capture even the smallest particles, ensuring the recycled water is clean enough for reuse in the separation process.
CleanTech also offers a hybrid solution that combines dry process and wet process technologies, minimizing the need for water in the first place. “We wanted to reduce our water usage without sacrificing metal recovery rates,” said a recycler in Australia. “CleanTech’s hybrid system did both—we’re using 60% less water, and our copper recovery is up by 5%.”
4. BlueSky Recycling Equipment
BlueSky, located in Wuxi, has made a name for itself with its modular water treatment systems. Whether you’re running a small WCBD-300A Circuit Board Recycling Plant (300-500 kg/hour) or a large-scale operation, BlueSky can customize a water treatment setup to fit your needs. Their most popular module? The PHBM Series Portable Briquette Machine , which compresses metal powder into briquettes—reducing waste and making transportation easier. But their water treatment modules are equally impressive, featuring ozone oxidation to break down organic pollutants and UV disinfection to kill bacteria.
BlueSky’s equipment is also known for its durability. Many of their systems have been in operation for over a decade with minimal maintenance. “We bought a BlueSky water treatment unit in 2015, and it’s still running like new,” said a recycler in Canada. “They use high-quality stainless steel components, so corrosion isn’t an issue—even with the acidic wastewater we generate.”
5. EarthGuard Machinery Co.
EarthGuard, based in Hangzhou, is a leader in eco-friendly recycling solutions. Their Water Process Equipment line includes everything from sedimentation tanks to ion exchange systems, but their standout product is the Multi-Stage Filter Press .
