Qingdao Conqinphi Environmental Technology Group Co., Ltd., established in 2015 with a factory spanning 10,000–30,000 square meters, offers the 70 TPH Triple-Effect Evaporation System – a high-efficiency solution for concentrating and recovering chemical wastewater. Our system is engineered to reduce waste volume, recover valuable byproducts, and lower operational costs, making it a core asset for industries dealing with complex effluents. With over 200 skilled employees and annual exports exceeding US$10 million, we deliver reliable, scalable evaporation technology trusted by clients across North America, Europe, Asia, and beyond.
This triple-effect system uses a series of three evaporators operating under decreasing pressure, allowing the vapor from one effect to heat the next. This design maximizes energy efficiency, reducing steam consumption by up to 60% compared to single-effect systems. The 70 TPH capacity suits large-scale chemical plants, refineries, and pharmaceutical manufacturing facilities where high-volume wastewater treatment is critical.
Key Features & Technical Specifications
- Triple-Effect Design: Three staged evaporation chambers maximize heat recovery, lowering energy consumption.
- High Capacity: Processes 70 tons of wastewater per hour, ideal for continuous industrial operations.
- Concentration & Recovery: Concentrates chemical waste to reduce disposal volume and recovers valuable solvents or water for reuse.
- Corrosion-Resistant Construction: Constructed from high-grade stainless steel (e.g., SS304, SS316L) or custom alloys for aggressive chemical environments.
- Automated PLC Control: Touch-screen interface with real-time monitoring, alarms, and remote access for easy operation.
- Multi-Energy Options: Can be powered by steam, electricity, or waste heat, adapting to site utilities.
- Compact Footprint: Modular design minimizes installation space while maintaining full performance.
- Compliance Ready: Designed to meet international environmental standards for wastewater discharge (customizable).

The triple-effect system offers significant advantages over traditional evaporation methods. By reusing vapor energy, it reduces overall energy costs by up to 60%. The concentrated wastewater can be disposed of more economically, and recovered distillate can be reused in production, lowering freshwater intake. For chemical plants producing high-COD (Chemical Oxygen Demand) streams, this system can achieve >95% volume reduction, turning waste into a manageable solid or slurry.
Benefits for Your Operation
- Lower Operating Costs: Reduced energy consumption and minimized waste disposal fees.
- Water Recovery: High-quality distillate can be recycled for cooling, cleaning, or process use.
- Environmental Compliance: Helps meet stringent discharge regulations by concentrating pollutants.
- Scalability: Modular design allows future expansion or integration with existing treatment lines.
- Minimal Maintenance: Robust construction and automated cleaning options reduce downtime.
- Customization: Tailored to handle specific chemical compositions, pH levels, and fouling tendencies.

Frequently Asked Questions (FAQ)
-
Q: What types of chemical wastewater can this system handle?
A: It is designed for a wide range of industrial effluents, including high-salinity, high-COD, and corrosive streams. The material of construction can be upgraded to titanium or other alloys for aggressive chemicals. Please provide your wastewater analysis for a customized recommendation. -
Q: How does triple-effect evaporation reduce energy consumption?
A: In a triple-effect system, the vapor from the first effect is used as the heating medium for the second effect, and so on. This reuses latent heat, achieving steam consumption as low as 0.4 kg per kg of water evaporated, compared to 1.0–1.1 kg in a single-effect unit. -
Q: What is the typical footprint of the 70 TPH system?
A: The exact dimensions depend on configuration (e.g., vertical or horizontal falling film). Typically, a 70 TPH triple-effect evaporator requires approximately 300–500 square meters of floor space, including auxiliary equipment. Our team can provide a layout drawing based on your site. -
Q: Can the system recover solvents or other valuable components?
A: Yes, if the wastewater contains recoverable organic solvents or chemicals, the system can be designed with separate condensate collection and distillation columns to recover them. Please specify your recovery goals. -
Q: What maintenance is required?
A: Routine maintenance includes checking pumps, valves, and seals, cleaning heat transfer surfaces (CIP system available), and inspecting instrumentation. The system is designed for low maintenance, with automatic fault detection alerts. -
Q: Do you provide installation and commissioning support?
A: Absolutely. We can send experienced engineers to supervise installation, perform commissioning, and train your operators. Remote support is also available via our service team. -
Q: What certifications does your company hold?
A: Our manufacturing facility is certified under ISO9001, ISO14000, OHSAS18001, HACCP, and other quality management systems. We also comply with international standards for export. -
Q: How long is the delivery time for a 70 TPH unit?
A: Typical lead time is 90–120 days after order confirmation, depending on customization and current production schedule. Shorter lead times may be available for standard configurations.
