As a leading manufacturer from Qingdao Conqinphi Environmental Technology Group Co., Ltd., we are proud to introduce our Compact MVR ZLD System for High Salinity Wastewater up to 25000ppm TDS. With over 9 years of expertise in wastewater treatment, our factory spanning 10,000-30,000 square meters and a dedicated team of 201-300 employees, we deliver reliable, energy-efficient solutions for zero liquid discharge (ZLD) applications. This system is designed to handle challenging brines and industrial effluents, ensuring maximum water recovery and minimal environmental impact.
Our MVR (Mechanical Vapor Recompression) technology reuses vapor compression heat to dramatically reduce energy consumption compared to traditional evaporators. The compact, skid-mounted design minimizes footprint and simplifies installation, making it ideal for projects with space constraints. Whether you are treating reverse osmosis concentrate, landfill leachate, or chemical process wastewater, this system achieves up to 99% water recovery while producing dry solids for disposal or reuse.
Key Features & Benefits
- High TDS Tolerance: Handles feed water with Total Dissolved Solids up to 25,000 ppm, with optional pre-treatment for higher concentrations.
- Energy Efficiency: MVR technology consumes only 50-70 kWh per ton of evaporated water, significantly lower than multi-effect evaporators.
- Compact Footprint: All components integrated on a single skid – reduces installation time and civil works cost.
- Fully Automated: PLC-based control with remote monitoring capability, reducing operator intervention.
- Modular Scalability: Multiple units can be combined to increase capacity from 10 m³/day to over 500 m³/day.
- Corrosion Resistance: Constructed with duplex stainless steel and other corrosion-resistant materials for long service life in aggressive environments.
- Zero Liquid Discharge: Produces high-purity distillate (

Frequently Asked Questions
-
Q: What is the maximum TDS level this system can treat?
A: The standard design handles up to 25,000 ppm TDS. For higher TDS (e.g., 50,000 ppm), we can add a pre-concentration stage or adjust the operating parameters. Please provide your feed water analysis for a customized solution. -
Q: How much energy does the MVR system consume compared to traditional evaporators?
A: Our MVR system typically consumes 50–70 kWh per ton of water evaporated, which is 60–70% less than multi-effect evaporators. Actual savings depend on feed composition and operating conditions. -
Q: Is the system suitable for batch or continuous operation?
A: It is designed for continuous 24/7 operation. For batch processes, we can integrate a buffer tank and control logic to handle fluctuating feed flow. -
Q: What kind of maintenance is required?
A: Regular maintenance includes cleaning the heat exchanger (frequency depends on scaling tendency), checking compressor oil, and inspecting seals. Our PLC system provides alerts for preventive maintenance. We also offer remote monitoring and annual service contracts. -
Q: Can the system handle varying feed quality?
A: Yes, the control system automatically adjusts compressor speed and feed flow to maintain stable operation. For significant changes in TDS or composition, we recommend a feed equalization tank and optional pre-treatment (e.g., softening, pH adjustment). -
Q: What is the typical delivery time?
A: For standard capacities (50–100 m³/day), delivery is 8–12 weeks after order confirmation. Larger or custom systems may require 14–16 weeks. We can expedite for urgent projects. -
Q: Does the system produce any liquid waste?
A: The system achieves zero liquid discharge. The distillate is reused, and the concentrated brine is further dried to produce solid salt or sludge, which can be disposed of or potentially reused as a byproduct. -
Q: What certifications does your company hold?
A: We are certified under ISO9001, ISO14000, OHSAS18001, and other management systems. Our products are manufactured in accordance with international standards. Specific certifications (e.g., ATEX, ASME) can be provided upon request for applicable projects.
