Qingdao Conqinphi Environmental Technology Group Co., Ltd., a leading manufacturer established in 2015 with a 10,000-30,000 sqm factory and over 200 experienced employees, proudly presents our Skid-Mounted MVR ZLD Unit featuring a 304SS Shell and Tube Heat Exchanger designed specifically for brine concentration. This system integrates advanced Mechanical Vapor Recompression (MVR) technology with Zero Liquid Discharge (ZLD) capabilities, delivering exceptional energy efficiency and reliable performance for industrial wastewater treatment. Our unit is pre-assembled on a robust skid, minimizing onsite installation time and ensuring rapid deployment for your brine concentration challenges.
The core of our MVR ZLD unit is a high-quality 304 stainless steel shell and tube heat exchanger, which provides excellent corrosion resistance and long service life even in aggressive brine environments. By reusing the latent heat of vaporized water, the system achieves up to 60-80% energy savings compared to traditional multi-effect evaporation. This translates directly into lower operational costs and a faster return on investment. The compact skid-mounted design incorporates all necessary components—compressor, pumps, piping, and control panel—streamlining installation, maintenance, and operation.
Key Features & Technical Specifications
- Energy Efficiency: MVR technology reduces steam consumption by recompressing vapor, requiring only electrical power for the compressor.
- Corrosion-Resistant Construction: 304SS shell and tube heat exchanger, with optional 316L for higher chloride concentrations.
- Skid-Mounted Design: Factory-assembled and tested, reducing field installation time by up to 50%.
- Automatic Control: PLC-based system with touchscreen HMI for real-time monitoring and remote operation.
- High Concentration Ratio: Capable of concentrating brine up to 20-25% total dissolved solids (TDS) or higher, depending on feed composition.
- Zero Liquid Discharge (ZLD): Recovers up to 95% of water as distillate, leaving a dry solids cake for disposal.
- Modular & Scalable: Multiple units can be combined for larger flow rates.
- Low Maintenance: Self-cleaning options and easy access to heat exchanger tubes for inspection.

Frequently Asked Questions (FAQ)
-
Q: What is the typical payback period for an MVR ZLD unit?
A: Depending on energy costs and brine characteristics, the payback period typically ranges from 2 to 4 years due to significant energy savings and reduced waste disposal fees. -
Q: Can this unit handle high-chloride brines (e.g., >30,000 ppm Cl⁻)?
A: Standard 304SS is suitable for moderate chloride levels. For highly corrosive brines, we recommend 316L stainless steel or duplex materials, which can be customized. -
Q: What is the maximum concentration achievable?
A: Our system can concentrate brine up to 20-25% TDS typically. Higher concentrations (e.g., saturation) require additional design considerations; we can evaluate your specific case. -
Q: Is the unit supplied with a compressor? What type?
A: Yes, we include a high-efficiency centrifugal or screw compressor (depending on capacity) designed for vapor recompression. All components are from reputable suppliers with proven track records. -
Q: How long does installation take?
A: Since the unit is skid-mounted and pre-tested, installation typically takes 1-2 weeks on site, including piping connections and electrical wiring. We provide on-site technical support if needed. -
Q: What certifications do your products have?
A: Our factory is ISO9001, ISO14000, and OHSAS18001 certified. We can also provide materials certificates, pressure vessel certificates (e.g., ASME, PED) upon request. -
Q: Can I get a sample or pilot unit for testing?
A: Yes, we offer rental pilot units for on-site testing to validate performance with your brine. Contact us for availability and terms. -
Q: What after-sales service do you provide?
A: We offer 12-month warranty, remote technical support, spare parts inventory, and optional maintenance contracts. Our service team is available 24/7 for emergencies.
