Qingdao Conqinphi Environmental Technology Group Co., Ltd. proudly presents our advanced Automatic Zero-Discharge Wastewater Equipment with Multi-Stage Filtration, 304SS Construction, and PLC Control. Designed for industries that demand maximum water recovery and environmental compliance, this system combines robust stainless steel durability with intelligent automation. Whether you are treating process water, cooling tower blowdown, or industrial effluent, our equipment ensures zero liquid discharge (ZLD) while minimizing operational costs. Built on our 10+ years of manufacturing experience, it delivers reliable performance for global markets.
Our multi-stage filtration process integrates pre-treatment, ultrafiltration, reverse osmosis, and advanced polishing to achieve contaminant removal rates above 99%. The 304 stainless steel framework resists corrosion and extends service life, while the PLC control system enables real-time monitoring, remote operation, and automatic adjustments. This equipment is ideal for industries such as chemicals, pharmaceuticals, food processing, textiles, and mining, where water reuse and discharge compliance are critical.
Key Features & Technical Specifications
- Zero-Discharge Capability: Recovers up to 95% of wastewater, leaving only a small brine concentrate that can be further processed or disposed.
- Multi-Stage Filtration: Includes grit removal, multimedia filtration, cartridge filtration, UF membrane, RO membrane, and optional MVR evaporator for complete ZLD.
- 304 Stainless Steel Construction: All wetted parts are made of 304SS, providing excellent resistance to corrosion, high temperatures, and pressure.
- PLC & HMI Control: Siemens or equivalent PLC with user-friendly touchscreen interface, supports remote monitoring via Ethernet/4G, and automatic alarm for faults.
- Energy Efficient: Variable frequency drives on pumps, energy recovery devices, and optimized membrane cleaning cycles reduce power consumption.
- Modular Design: The system can be customized to fit your site layout, with skid-mounted or containerized options.
- Compliance Ready: Meets international standards for wastewater discharge and reuse, with optional certification for HACCP, TL900, etc.

Frequently Asked Questions
- Q: What is the typical lifespan of the equipment? A: With proper maintenance, the 304SS components and membranes can last 10–15 years. PLC components have a typical lifespan of 8–10 years.
- Q: Can this system handle high-salinity wastewater? A: Yes, the multi-stage design includes RO membranes that can handle TDS up to 40,000 mg/L. For higher salinity, we can add an MVR evaporator.
- Q: Is the PLC control system compatible with SCADA? A: Yes, our PLC supports Modbus TCP/IP, Profibus, and OPC UA, allowing easy integration with existing SCADA or DCS systems.
- Q: What is the footprint of a 10 m³/h unit? A: Approximate dimensions: 6m (L) × 2.5m (W) × 2.8m (H) for a skid-mounted configuration. Containerized solutions are also available.
- Q: Do you provide installation and commissioning services? A: Yes, we offer on-site supervision by our engineers or remote guidance. Training for operators is included.
- Q: How does the automatic cleaning cycle work? A: The PLC triggers backwash, chemical cleaning, or membrane flushing based on pressure differential or time schedule. This reduces manual intervention.
- Q: What certifications does the equipment have? A: Our manufacturing facility is ISO9001, ISO14000, and OHSAS18001 certified. The equipment can be customized to meet CE, or other standards upon request.
- Q: Can I get a sample or pilot test before purchase? A: Absolutely. We offer rental pilot units for on-site testing, typically for 1–2 weeks, to validate performance on your specific wastewater.
