Qingdao Conqinphi Environmental Technology Group Co., Ltd. is proud to present our Zero-discharge wastewater equipment for the electroplating industry, designed to remove heavy metals and meet stringent discharge standards. With over 8 years of experience in environmental technology, our factory spans 10,000-30,000 square meters and employs 201-300 skilled professionals, ensuring high-quality manufacturing. This equipment is engineered to achieve true zero liquid discharge (ZLD), converting wastewater into reusable water and solid waste, while recovering valuable metals — a cost-effective and sustainable solution for electroplating plants.
Our system integrates advanced technologies such as MVR evaporation, reverse osmosis, ion exchange, and electrodialysis to effectively remove heavy metals like chromium, nickel, copper, and zinc. The treated water meets or exceeds local discharge standards and can be directly recycled back into the production process, reducing water consumption by up to 95%. Below are the key features and specifications:
| Feature | Specification |
|---|---|
| Treatment Capacity | 1 - 100 m³/h (customizable) |
| Heavy Metal Removal Efficiency | ≥99.5% |
| Water Recovery Rate | ≥95% |
| Operating Temperature | 5°C - 50°C |
| Power Consumption | 0.5 - 2.5 kWh/m³ (depending on process) |
| Material of Construction | 304 Stainless Steel / Carbon Steel (anti-corrosion coating) |
| Automation Level | Full PLC control, touch screen, remote monitoring optional |
| Certifications | ISO9001, ISO14000, OHSAS18001, SA8000, QS9000, etc. |
Detailed Product Advantages
- Zero Discharge Compliance: No liquid effluent is discharged, meeting the strictest environmental regulations in electroplating industry.
- Resource Recovery: Valuable heavy metals (e.g., nickel, copper) can be recovered and reused, offsetting operational costs.
- Modular Design: The system is skid-mounted and easy to install, expand, or relocate according to changing production needs.
- Low Operating Cost: Advanced MVR evaporation technology reduces energy consumption compared to traditional thermal methods.
- Durable Construction: All components are corrosion-resistant, ensuring long service life in harsh chemical environments.
- Smart Automation: PLC control with fault alarms and automatic shutdown ensures safe and stable operation with minimal manpower.
- Customizable Options: Pre-treatment, post-treatment, and sludge dewatering units can be integrated based on specific wastewater characteristics.
Our equipment is widely used in electroplating, metal finishing, PCB manufacturing, and surface treatment industries. It effectively handles complex wastewater with high concentrations of heavy metals, cyanide, and organic compounds. The treated water quality typically meets GB 21900-2008 (China's emission standard for electroplating) or comparable international standards.

Frequently Asked Questions (FAQs)
-
Q: What is the typical payback period for this zero-discharge system?
A: The payback period usually ranges from 1 to 3 years, depending on water volume, metal content, and local water costs. Metal recovery can significantly shorten the payback time. -
Q: Can this equipment handle cyanide-containing wastewater from electroplating?
A: Yes, we offer a pre-treatment module (e.g., alkaline chlorination) to break down cyanide before the main ZLD process. The system can be customized accordingly. -
Q: What is the required footprint for a 10 m³/h system?
A: Approximately 50-80 m² (including pre-treatment and sludge handling). Our modular design can be optimized for tight spaces. -
Q: How often does the membrane need to be replaced?
A: Membrane lifespan is typically 2-5 years under proper operation and maintenance. We provide cleaning protocols and online monitoring to extend membrane life. -
Q: Do you provide training for operators?
A: Yes, we offer on-site training for your team as part of the commissioning package, covering operation, maintenance, and troubleshooting. -
Q: Is the system compliant with international standards for export?
A: Our equipment is designed to meet various international standards, and we can adapt to local regulations. We have shipped to over 30 countries with successful compliance records. -
Q: What is the warranty period?
A: We offer a standard 2-year warranty on major components, with extended warranty options available upon request. -
Q: Can you test my wastewater sample before purchasing?
A: Absolutely. We provide free laboratory testing and pilot trials to confirm the treatment efficiency and recommend the best configuration.
