As a leading manufacturer specializing in advanced environmental solutions, Qingdao Conqinphi Environmental Technology Group is proud to present our high-performance Multi-Effect Evaporator system. Engineered for demanding industrial wastewater treatment and Zero Liquid Discharge (ZLD) applications, this system represents our commitment to providing reliable, energy-efficient, and sustainable concentration technology. With over 8 years of industry experience since our establishment in 2015, we have refined our designs to tackle complex effluent streams, helping clients meet stringent environmental regulations, recover valuable resources, and minimize their liquid waste footprint. Our systems are built to deliver consistent performance, reduce operational costs, and provide a robust solution for achieving true zero liquid discharge goals.
Our Multi-Effect Evaporator is a cornerstone technology for volume reduction and resource recovery. It operates on the principle of using vapor from one evaporation effect as the heating medium for the next, significantly improving thermal efficiency compared to single-effect units. This design is particularly effective for treating high-salinity, high-COD, or complex chemical wastewater where conventional methods fall short.
- Superior Energy Efficiency: By reusing latent heat across multiple effects, our system drastically cuts steam consumption. Energy savings of 60-80% are achievable compared to single-effect evaporators, leading to substantially lower operating expenses.
- Robust Construction for Corrosive Streams: We select materials based on a thorough analysis of your feed chemistry. Common constructions include 316L stainless steel for general applications, 2205 duplex stainless for chlorides, and titanium for highly corrosive or high-temperature services, ensuring long equipment life and minimal maintenance.
- Flexible Configuration & Integration: The system can be configured as a traditional Multiple-Effect (MED), Mechanical Vapor Recompression (MVR), or Thermal Vapor Recompression (TVR) unit. It integrates seamlessly with upstream pre-treatment (e.g., softening, filtration) and downstream crystallizers or dryers for complete ZLD process trains.
- Intelligent Automated Control: A centralized PLC-based control system with a user-friendly HMI allows for precise monitoring and adjustment of key parameters like temperature, pressure, level, and conductivity. This ensures stable operation, product consistency, and allows for remote monitoring capabilities.
- Scalable and Customizable Design: We design each system based on client-specific feed composition, flow rate, and final concentrate/discharge requirements. Capacities are scalable, making it suitable for various industries from pharmaceuticals and chemicals to power generation and mining.
Key technical specifications and configurations are summarized in the table below. Please note these are typical ranges, and final design will be optimized for your project.
| Parameter | Specification / Option |
|---|---|
| Number of Effects | 2 to 6 effects (standard), more available |
| Evaporator Type | Forced Circulation (FC), Falling Film, or Plate |
| Heat Transfer Area (per effect) | Custom designed, from 50 m² to 2000 m²+ |
| Concentration Factor | Can achieve TDS > 250,000 mg/L, near saturation |
| Steam Economy (MED) | Up to 0.8 - 1.2 kg evaporation per kg steam (for 3-4 effect) |
| Condensate Quality | High-purity water, often suitable for reuse (e.g., boiler feed) |
The advantages of implementing our Multi-Effect Evaporator translate into direct benefits for your operation. You achieve regulatory compliance by eliminating liquid discharge, reduce waste disposal costs through volume reduction, and potentially recover valuable by-products or high-quality water for reuse. The high energy efficiency also provides a strong defense against rising energy costs, improving your plant's overall sustainability profile.
Backed by our substantial manufacturing capabilities in a 10,000-30,000 square meter facility and a dedicated team of 201-300 professionals, Qingdao Conqinphi delivers not just equipment, but reliable performance.

Frequently Asked Questions (FAQ)
Q1: What types of wastewater are suitable for this Multi-Effect Evaporator?
A: This system is highly effective for a wide range of industrial effluents, including those from chemical processing, pharmaceutical production, power plant flue gas desulfurization (FGD) wastewater, landfill leachate, textile dyeing, and metal finishing. It handles high TDS, high COD, and complex organics effectively.
Q2: How does the energy consumption compare to a single-effect evaporator?
A: Energy consumption is significantly lower. A multi-effect system recycles vapor heat, so the steam required per kilogram of water evaporated can be reduced by approximately 50% in a double-effect and up to 80% in a quadruple-effect system compared to a single-effect unit.
Q3: Is pre-treatment of the wastewater always necessary?
A: In most cases, yes. Pre-treatment such as pH adjustment, softening to remove scaling ions (calcium, magnesium), and filtration to remove suspended solids is crucial. It protects the evaporator from scaling and fouling, ensuring stable, long-term operation and minimizing downtime for cleaning.
Q4: What is the typical delivery and installation timeline for a custom system?
A: The timeline varies based on capacity and complexity. Generally, from detailed design to factory acceptance testing, it takes approximately 6 to 10 months for a standard system. Installation and commissioning on-site typically require an additional 2 to 3 months, supported by our technical team.
Q5: Can the system handle wastewater with volatile organic compounds (VOCs)?
A: Yes, but it requires specific design considerations. We can integrate vapor scrubbing or condensation systems to manage VOCs. The evaporator type (e.g., forced circulation) and operating pressure/temperature are selected to minimize VOC stripping or to facilitate their capture and treatment.
Q6: What kind of after-sales support and training do you provide?
A: We provide comprehensive support including detailed operation & maintenance manuals, on-site training for your operators and maintenance staff, remote technical support, and a supply of recommended spare parts. Service engineers are available for periodic inspections.
Q7: How is the final concentrated brine or slurry handled?
A> The evaporator produces a concentrated slurry or brine. For full ZLD, this stream is typically sent to a downstream crystallizer to produce solid salts or to a slurry dryer. We can design and supply the complete evaporation-crystallization package.
Q8: Are your systems designed to specific international pressure vessel codes?
A> Yes. Our designs can comply with major international codes such as ASME Section VIII, PED (Pressure Equipment Directive), or Chinese GB150 standards, depending on the destination market and client requirements. Material certifications and design calculations are provided.
