As a leading manufacturer from Qingdao Conqinphi Environmental Technology Group Co., Ltd. (established 2015), we proudly present our Three Effect Plate Evaporator constructed entirely from premium titanium material. This industrial evaporator is specifically engineered for the efficient recovery of water and valuable components from highly corrosive wastewater streams, such as those found in chemical processing, metal finishing, and pharmaceutical industries. By combining advanced three-effect evaporation technology with titanium's exceptional corrosion resistance, we deliver a solution that maximizes energy savings (up to 60% compared to single-effect units) while ensuring long-term operational reliability even in the harshest environments.
Our factory spans 10,000–30,000 m² with a team of 201–300 skilled professionals, and we export over $10 million annually to markets across North America, South America, Europe, Asia, and Africa. Every evaporator undergoes rigorous quality control, backed by certifications including ISO9001, ISO14000, OHSAS18001, and HACCP. Below we detail the technical specifications and benefits that make this equipment a top choice for corrosive wastewater recovery.
Key Features & Technical Specifications
- Three-Effect Design: Enhanced thermal efficiency through vapor recompression in three stages, reducing steam consumption by up to 50–70% compared to single-effect evaporators.
- Pure Titanium Construction: Plates, frames, and piping are made from TA2 or TA10 titanium, providing outstanding resistance to chlorides, sulfuric acid, nitric acid, and organic acids.
- Modular Plate Configuration: Easy to expand or adjust heat transfer area (100–500+ m²) to match specific flow rates and concentration requirements.
- Low Fouling & Easy Cleaning: Smooth titanium surfaces minimize scale buildup; plates can be disassembled for manual or CIP cleaning.
- Automatic Control System: PLC with HMI touchscreen for real-time monitoring of temperature, pressure, flow, and liquid levels.
- Corrosion-Resistant Gaskets: EPDM, Viton, or PTFE gaskets chosen based on wastewater chemistry.
- Compact Footprint: Saves valuable floor space compared to traditional tubular evaporators.
- Optional Vacuum Operation: Allows boiling at lower temperatures to handle heat-sensitive liquids.

Benefits for Your Business
- Significant Operating Cost Reduction: The three-effect design cuts steam consumption by half or more, lowering your energy bills dramatically.
- Extended Equipment Lifespan: Titanium's corrosion resistance means no pitting or stress corrosion cracking, even with high chloride concentrations. Many units operate for 15+ years with minimal maintenance.
- High Purity Recovered Water: The plate evaporator produces distillate with very low TDS, suitable for reuse in processes or discharge.
- Concentration of Valuable Byproducts: Recover acids, salts, or metals from wastewater for resale or reuse, turning waste into profit.
- Compliance with Environmental Regulations: Achieve zero liquid discharge (ZLD) goals and meet stringent discharge limits.

Frequently Asked Questions (FAQ)
-
Q: What types of corrosive wastewater can this evaporator handle?
A: The titanium plate evaporator is suitable for acidic solutions (sulfuric, hydrochloric, nitric), alkaline solutions (caustic soda), salt solutions (chlorides, sulfates), and mixed streams. It is widely used in pickling baths, metal finishing, chemical manufacturing, and pharmaceutical waste. -
Q: How does the three-effect system save energy compared to a single-effect evaporator?
A: In a three-effect evaporator, the vapor from the first effect is used as heating medium in the second effect, and vapor from the second heats the third. This cascade reuses thermal energy, reducing steam consumption to about 0.4 kg per kg of water evaporated (vs. 1.1–1.2 for single-effect). -
Q: Is the titanium material resistant to all corrosive chemicals?
A: Titanium offers excellent resistance to most oxidizing acids and chlorides but is not recommended for pure hydrofluoric acid or concentrated sulfuric acid above 10% at high temperatures. For special chemistries, we can advise on alternative alloys (e.g., Hastelloy) or gasket materials. -
Q: What is the typical lead time for delivery?
A: Depending on the customization level, lead time ranges from 45 to 90 days. Standard models can be shipped within 60 days. We ship from Qingdao port, China. -
Q: Do you provide installation and commissioning support?
A: Yes, we provide on-site installation supervision by our engineers (travel expenses covered by client) and detailed manuals. Remote video guidance is also available. -
Q: Can the evaporator achieve zero liquid discharge (ZLD)?
A: Yes, when combined with a crystallizer or dryer, our three-effect plate evaporator can concentrate wastewater to near dryness, allowing ZLD. We can design the complete system for your requirements. -
Q: What kind of after-sales service do you offer?
A: We offer 12-month warranty covering defects in materials and workmanship. Spare parts (gaskets, plates, seals) are available from stock. Our support team responds within 24 hours. -
Q: How often does the plate pack need to be cleaned?
A: Cleaning frequency depends on feed quality. For typical industrial wastewater, cleaning every 2–4 months is recommended. The plate design allows easy disassembly for mechanical or chemical cleaning.
