Qingdao Conqinphi Environmental Technology Group Co., Ltd., a professional manufacturer founded in 2015 with a factory area of 10,000-30,000 square meters and over 200 employees, proudly presents our Double-effect Evaporation Equipment for Pharmaceutical Wastewater Treatment and Concentration. This advanced system is designed to efficiently reduce the volume of pharmaceutical wastewater while recovering valuable concentrates, achieving significant energy savings and operational cost reduction. Our equipment is trusted by clients across North America, Europe, Southeast Asia, and other global markets, backed by annual exports of US$10-50 million.
The double-effect evaporation process utilizes the latent heat of vapor from the first effect to drive evaporation in the second effect, substantially lowering steam consumption compared to single-effect systems. This makes it an ideal solution for pharmaceutical plants that need to treat high-strength wastewater containing organic solvents, APIs, and other contaminants, while also concentrating the waste for easier disposal or potential reuse.
Key Features & Technical Specifications
- Energy-efficient double-effect design – Reduces steam consumption by up to 40% compared to single-effect evaporators.
- Corrosion-resistant construction – Made from high-grade stainless steel 304 or 316L, suitable for aggressive pharmaceutical wastewater.
- Vacuum operation – Lowers boiling point to minimize thermal degradation of sensitive compounds.
- PLC automatic control – Ensures stable operation, easy monitoring, and minimal manual intervention.
- Compact footprint – Space-saving design fits into existing production lines.
- Modular configuration – Customizable capacity and auxiliary equipment (condenser, vacuum pump, etc.) to meet specific site requirements.

Advantages & Customer Benefits
- Significant energy savings – The double-effect design reuses heat, cutting energy costs by up to 40%.
- High concentration ratio – Achieves a final solid content of 30-60% depending on wastewater characteristics, reducing disposal volume.
- Low maintenance – Simple structure, easy cleaning, and long service life of components.
- Environmental compliance – Helps meet stringent discharge standards by reducing pollutant load.
- Flexible integration – Can be combined with pre-treatment (e.g., MVR, membrane) or post-treatment (e.g., crystallization) for complete solutions.
Our double-effect evaporator has been successfully deployed in numerous pharmaceutical wastewater projects worldwide, treating streams containing solvents like ethanol, acetone, and methanol, as well as high-salinity effluents. The system is designed to run continuously with minimal downtime, ensuring maximum productivity for your facility.
Frequently Asked Questions (FAQ)
-
Q: What is the difference between single-effect and double-effect evaporation?
A: Double-effect evaporation uses the vapor from the first effect to heat the second effect, requiring less than half the steam of a single-effect system. This results in higher energy efficiency and lower operating costs. -
Q: Can this equipment handle high-viscosity or fouling wastewater?
A: Yes, we offer options such as forced circulation or scraped surface designs to handle viscous or scaling liquids. Our team can recommend the best configuration based on your wastewater analysis. -
Q: What is the typical payback period for this equipment?
A: Depending on local energy costs and wastewater volume, the payback period is usually between 12 to 24 months due to significant steam savings and reduced disposal fees. -
Q: Is the equipment suitable for batch or continuous operation?
A: Our double-effect evaporator is designed for continuous operation, but it can also be adapted for batch processing if required. The PLC control system allows flexible operation modes. -
Q: What certifications does your company hold?
A: We are certified under ISO9001, ISO14001, OHSAS18001, and other management systems, ensuring consistent quality and environmental responsibility. Our products meet international standards. -
Q: Do you provide installation and after-sales service?
A: Yes, we offer on-site installation supervision, commissioning, training, and 24/7 technical support. Our global service network ensures quick response. -
