As a leading manufacturer in the environmental technology field since 2015, Qingdao Conqinphi Environmental Technology Group Co., Ltd. brings you a state-of-the-art solution for high-salt wastewater treatment. Our RO + MVR Combined Zero-Discharge System is engineered to handle a capacity of 1000 m³/day while achieving an outstanding 99% water recovery rate. This integrated approach eliminates liquid waste discharge, turning problematic brine into reusable water and solid salt byproducts, aligning with global sustainability goals.
The system combines Reverse Osmosis (RO) pre-concentration with Mechanical Vapor Recompression (MVR) evaporation, ensuring maximum efficiency and minimal energy consumption. Each unit is built with high-quality corrosion-resistant materials and features a fully automated PLC control system for reliable, unmanned operation. Whether you need to treat industrial wastewater from chemical, pharmaceutical, or mining processes, our solution provides a robust, cost-effective path to zero liquid discharge (ZLD).
Backed by over 9 years of manufacturing experience and a factory spanning 10,000–30,000 square meters, we deliver consistent quality and performance. Our products have been exported to major markets worldwide, including North America, Europe, Southeast Asia, and Oceania, with an annual export value of US$10–50 million. Below are the detailed technical specifications and features of this system.

Product Features and Benefits
- Zero Liquid Discharge (ZLD) Compliance: The combined RO and MVR process ensures that no liquid waste leaves the system. Fresh water is recovered for reuse, while concentrated brine is evaporated to produce dry solids. This helps industries meet stringent environmental regulations.
- High Energy Efficiency: MVR technology recycles the latent heat from vapor compression, reducing energy consumption by up to 50–70% compared to traditional evaporation methods. The RO pre-concentration further lowers the thermal load on the MVR stage.
- Fully Automated Operation: Equipped with a PLC-based control system and user-friendly HMI, the plant can run continuously with minimal manual intervention. Parameters such as pressure, temperature, flow rate, and conductivity are monitored in real time.
- Robust and Durable Construction: All wetted parts are made of high-grade stainless steel or corrosion-resistant alloys, ensuring long service life even under high salinity and acidic/alkaline conditions.
- Modular and Scalable Design: The system is designed in a skid-mounted or containerized configuration for easy installation and expansion. Capacity can be scaled up by adding parallel modules.
- Low Maintenance Requirements: With self-cleaning RO membranes and anti-scaling MVR evaporators, the system requires less frequent chemical cleaning. Spare parts are readily available globally.
- Customizable for Different Wastewater Types: Whether your wastewater contains chlorides, sulfates, nitrates, or heavy metals, we can tailor the pretreatment and membrane selection to optimize performance.
Our manufacturing facility operates under strict quality management systems, including ISO9001, ISO14000, OHSAS18001 and other international standards. With a team of 201–300 skilled employees, we ensure every system is tested thoroughly before shipment. Since 2015, we have successfully delivered hundreds of wastewater treatment projects across more than 20 countries.
Trusted by Global Industries: From chemical plants in the Middle East to mining operations in South America, our clients rely on Conqinphi for durable and efficient zero-discharge solutions. Our annual export value of US$10–50 million reflects the trust and satisfaction of our international partners. We provide comprehensive after-sales support, including on-site installation guidance, remote troubleshooting, and spare parts supply.
If you are looking for a reliable, high-recovery, and cost-effective zero-discharge wastewater treatment system for your high-salt effluent, the RO + MVR Combined 1000 m³/day System is your ideal choice. Contact us today for a customized proposal and join hundreds of satisfied customers worldwide.
