Qingdao Conqinphi Environmental Technology Group Co., Ltd. presents our advanced PLC-Controlled MVR Evaporation Crystallization System, meticulously engineered for efficient industrial wastewater treatment. As a manufacturer with over 8 years of expertise and a factory spanning 10,000-30,000 square meters, we deliver robust solutions that transform high-salinity wastewater into reusable water and valuable crystals. This system, constructed from premium 316L stainless steel and capable of processing 1000 liters per hour, offers unmatched energy efficiency through mechanical vapor recompression (MVR) technology. Our PLC-based automation ensures precise, stable operation, reducing manual intervention and overall operational costs. Whether you face challenging effluents from chemical, pharmaceutical, or food processing industries, this system provides a sustainable, zero-liquid-discharge (ZLD) path.
The core technology of MVR (Mechanical Vapor Recompression) significantly lowers steam consumption by reusing the latent heat of vaporized water. Compared to traditional multi-effect evaporation, our system can achieve up to 30-50% energy savings. The complete unit includes a PLC controller, heat exchanger, vapor-liquid separator, compressor, circulation pumps, and control valves. All wetted parts are made of 316L stainless steel, offering excellent corrosion resistance against chlorides, acids, and alkalis commonly found in industrial effluents.

Product Features & Benefits:
- Energy Efficient MVR Technology: Recycles vapor heat, reducing overall energy consumption by up to 60% compared to conventional evaporators. Lower operating costs pay back investment faster.
- PLC Automation: Touchscreen HMI allows easy monitoring of temperature, pressure, flow, and crystal concentration. Automatic start/stop, alarm, and remote data logging reduce labor requirements.
- High Corrosion Resistance: 316L stainless steel construction ensures long service life even with aggressive chloride-rich wastewater. Optional surface treatment for extreme conditions.
- Scalable and Customizable: While the standard model delivers 1000 L/h, we offer customization of capacity, materials, and control logic to match your specific waste stream. Options include antiscalant dosing, CIP cleaning system, and multi-stage crystallization for high-purity salts.
- Zero Liquid Discharge (ZLD) Capability: Our system concentrates wastewater to near-dryness, producing solid crystals and clean distilled water that can be recycled back into production. Ideal for meeting strict environmental regulations.
- Robust Performance: Designed for continuous 24/7 operation with minimal downtime. The compressor and pumps are selected from top brands (e.g., Atlas Copco or equivalent).
- Compact Footprint: Skid-mounted design reduces installation space and simplifies site integration. Pre-wired and pre-piped for quicker commissioning.
- Comprehensive Safety Features: Over-temperature, over-pressure, and low-level protection integrated into PLC logic. Emergency stop and audible alarms ensure operator safety.

Frequently Asked Questions (FAQ)
-
Q: What types of wastewater can this system handle?
A: It is suitable for high-salinity industrial wastewater from chemical, pharmaceutical, food processing, textile, and mining industries. The optimal TDS range is 30,000–200,000 mg/L. For specific compositions, we recommend a lab test or pilot trial. -
Q: How much energy does the MVR system save compared to traditional evaporation?
A: Typically, MVR systems consume 30–50% less energy than multi-effect evaporators. The actual savings depend on feed concentration and operating conditions. -
Q: Is the control system compatible with remote monitoring?
A: Yes, our PLC supports Modbus, Profibus, or Ethernet communication protocols. Remote monitoring and data acquisition can be integrated upon request. -
Q: What is the maintenance schedule for the system?
A: Routine maintenance includes checking compressor oil, cleaning heat exchanger surfaces (periodic CIP), and inspecting seals. Our manual provides a detailed schedule. We also offer annual service contracts. -
Q: Can the system handle wastewater with high scaling potential?
A: Yes, we can integrate anti-scalant dosing and design the crystallizer with forced circulation to minimize scaling. Optional crystal seed bed is available for supersaturation control. -
Q: What is the delivery lead time?
A: Standard units typically require 60–90 days after order confirmation, depending on customization level. We can provide a precise timeline upon request. -
Q: Do you provide installation and commissioning support?
A: Yes, our engineers can supervise installation and commissioning on-site. Video training and remote support are also available. -
Q: What certifications does the system hold?
A: Our manufacturing processes comply with ISO9001, ISO14000, and OHSAS18001 standards. Specific certifications for your region (e.g., CE, ATEX) can be arranged upon request.
