Introducing our MVR Crystallization Evaporator with CIP Cleaning and IP65 Inverter Drive – a high-efficiency solution designed for zero liquid discharge (ZLD) applications. As a leading manufacturer from Qingdao Conqinphi Environmental Technology Group Co., Ltd. (established 2015, 10,000-30,000 m² factory), we combine advanced mechanical vapor recompression technology with robust automation to deliver reliable crystallization and evaporation performance. This system integrates an IP65-rated inverter drive for precise motor control and a Clean-in-Place (CIP) function that minimizes downtime and maintenance costs. Built for demanding industrial wastewater treatment, our evaporator ensures maximum water recovery and solid separation, supporting your sustainability goals.
Our MVR (Mechanical Vapor Recompression) technology significantly reduces energy consumption by reusing vapor compression heat. The crystallization process produces high-purity solids, making it ideal for brine concentration, chemical recovery, and zero-liquid-discharge compliance. Let’s explore its key features and technical specifications.
Key Features & Benefits
- Energy Efficiency: The MVR system reuses vapor heat, lowering operational costs by up to 60% compared to traditional thermal evaporators.
- IP65 Inverter Drive: Provides dust-tight and water-protected operation, ensuring reliable performance in harsh industrial environments. Variable frequency control optimizes compressor speed for varying feed conditions.
- CIP Cleaning System: Automated cleaning cycle reduces manual labor and extends equipment lifespan. CIP nozzles and spray balls ensure thorough cleaning of evaporator tubes and crystallizer surfaces.
- Zero Liquid Discharge (ZLD) Capability: Achieves >99% water recovery, leaving dry solids for safe disposal or further processing. Complies with stringent environmental regulations.
- Robust Construction: Made from high-grade stainless steel (SS304 or SS316L) to resist corrosion from brines and aggressive chemicals.
- PLC Automation: Touch-screen HMI with remote monitoring options; integrates seamlessly with existing plant control systems.
- Compact Footprint: Modular design allows easy installation and scalability.

Detailed Advantages for Customers
Our MVR Crystallization Evaporator is engineered to deliver consistent, high-quality output with minimal operator intervention. The IP65 inverter drive protects against dust ingress and water jets, making it suitable for outdoor or wash-down areas. The CIP system reduces cleaning cycles from hours to minutes, improving overall equipment effectiveness (OEE). The crystallization process produces well-formed crystals that are easy to separate, reducing downstream filtration costs.
Zero liquid discharge (ZLD) is increasingly mandated by environmental agencies. Our system can handle high TDS brines, including those from RO concentrate, industrial effluents, and mining operations. By recovering up to 99% of water as distillate, you cut freshwater consumption and eliminate liquid waste discharge. The solids produced (e.g., mixed salts) can be landfilled or repurposed.
FAQ (Frequently Asked Questions)
-
Q: What is the typical energy savings compared to a falling film evaporator?
A: Our MVR system typically saves 50-70% energy, as it recycles vapor compression heat instead of using steam. -
Q: Can the CIP cleaning process be customized for different scaling materials?
A: Yes. Our CIP sequence can be programmed with multiple rinses, caustic/acid wash, and deionized water flush, adjustable via the PLC. -
Q: How does the IP65 inverter drive handle power fluctuations?
A: The VFD includes built-in surge protection and voltage stabilization, ensuring stable compressor operation even in unstable grid conditions. -
Q: What is the maximum solid concentration achievable in the crystallizer?
A: Typically up to 20-30% solids by weight, depending on salt solubility. We can design for higher concentrations using special separators. -
Q: Is the evaporator suitable for highly corrosive feeds like acidic wastewater?
A: Yes. We offer material upgrades (e.g., Hastelloy or titanium) for extreme pH conditions. Please provide your feed analysis for a customized solution. -
Q: What after-sales support do you provide?
A: We offer on-site commissioning, training, remote diagnostics, and spare parts. Our 200+ staff and ISO-certified quality system ensure responsive service. -
Q: Can this system be retrofitted into an existing evaporation plant?
A: Often yes. Our modular design allows integration with pre-existing heaters, condensers, and piping. We provide a feasibility study upon request. -
Q: What certifications does your equipment hold?
A: Our manufacturing facility is ISO9001, ISO14000, OHSAS18001, and HACCP certified, among others. Specific equipment can be designed to meet CE or ASME standards per request.
