Product Introduction
As a leading manufacturer based in Qingdao, China, Qingdao Conqinphi Environmental Technology Group Co., Ltd. has been dedicated to sustainable water treatment solutions since 2015. Our 304 Stainless Steel High-Salt Wastewater Zero Liquid Discharge (ZLD) System with MVR Compressor represents the pinnacle of efficient, corrosion-resistant technology for industries facing stringent discharge regulations. By integrating a mechanical vapor recompression (MVR) compressor, this system achieves high evaporation rates while minimizing energy consumption—turning problematic high-salinity wastewater into clean condensate and dry solids. Backed by a 10,000–30,000 m² factory and over 200 skilled professionals, we deliver reliable, customized zero liquid discharge solutions worldwide.
Key Features & Technical Specifications
- Superior Corrosion Resistance – Constructed from 304 stainless steel, the system withstands aggressive high-salt and acidic wastewater, ensuring long service life and low maintenance.
- Energy-Efficient MVR Compressor – The MVR compressor recovers latent heat from vapor, reducing steam consumption by up to 60–80% compared to traditional multi-effect evaporators.
- Automatic PLC Control – Touch-screen operation with real-time monitoring of temperature, pressure, flow, and compressor status; supports remote control and data logging.
- Zero Liquid Discharge Compliance – Produces distilled water (TDS < 50 ppm) and solid salt crystals, meeting environmental discharge or reuse standards.
- Compact Modular Design – Pre-assembled skid-mounted units simplify installation, reduce footprint, and allow easy capacity expansion.
