Qingdao Conqinphi Environmental Technology Group Co., Ltd., a leading manufacturer with over 8 years of experience in the environmental industry, proudly presents our LTE Falling Film Evaporator for High-Salt Wastewater Treatment. This state-of-the-art equipment is specifically designed to efficiently concentrate and treat high-salinity wastewater streams, reducing disposal costs and recovering valuable water resources. With a factory spanning 10,000–30,000 square meters and a dedicated team of 201–300 employees, we deliver reliable, high-performance solutions to clients worldwide.
The LTE series utilizes advanced falling film technology combined with a unique film distribution system, ensuring uniform liquid distribution and minimal scaling. This evaporator is ideal for industries such as chemicals, pharmaceuticals, textiles, and oil & gas, where high-salt wastewater poses a significant challenge. Our system is built to withstand corrosive environments, operates at low energy consumption, and offers customizable configurations to meet specific process requirements.
Key Features & Technical Specifications
- High Efficiency Falling Film Design – The liquid flows as a thin film over heated tubes, maximizing heat transfer and reducing residence time, which minimizes thermal degradation and scaling.
- Anti-Scaling & Anti-Corrosion – Constructed from high-grade stainless steel (SS304/SS316L) with optional special coatings, our evaporator handles high-salt and corrosive streams effectively.
- Low Energy Consumption – Utilizes vapor recompression or multiple-effect configurations to reduce steam usage by up to 50% compared to traditional evaporators, lowering operational costs.
- Fully Automatic Control System – PLC-based automation with touch screen interface allows precise monitoring of temperature, pressure, flow rate, and concentration, ensuring stable operation with minimal manual intervention.
- Compact Footprint – Modular design saves valuable floor space and simplifies installation, even in retrofit projects.
- Easy Maintenance – Quick-opening design and accessible heat exchange tubes facilitate cleaning and inspection, reducing downtime.

Frequently Asked Questions (FAQ)
Q1: What types of high-salt wastewater can this evaporator handle?
A: It is suitable for a wide range of salt solutions, including sodium chloride, sodium sulfate, calcium chloride, magnesium chloride, and mixed salt streams from chemical, pharmaceutical, textile, and mining industries.
Q2: How do you prevent scaling in the evaporator?
A: Our falling film design minimizes liquid residence time and uses a continuous film to reduce scaling. Additionally, we can incorporate anti-scalant dosing, periodic CIP (clean-in-place) systems, and optional special tube coatings.
Q3: What is the typical energy consumption?
A: Depending on the configuration (single-effect, multiple-effect, or MVR), steam consumption ranges from 0.3 to 0.6 kg steam per kg of water evaporated. For MVR (mechanical vapor recompression) systems, electricity consumption is typically 30–70 kWh per ton of water evaporated.
Q4: Can the evaporator operate continuously?
A: Yes, it is designed for 24/7 continuous operation with automatic control and minimal manual intervention. Periodic maintenance is recommended every 3–6 months depending on feed quality.
Q5: What is the maximum concentration I can achieve?
A: The achievable concentration depends on the salt type and solubility. Typically, we can concentrate solutions to 20–30% solids content, and in some cases up to 40% with special designs. Further treatment (e.g., crystallization) can be added for ZLD.
Q6: Do you provide installation and commissioning support?
A: Yes, we offer on-site installation supervision, commissioning, and training for operators. Remote support is also available via video call for troubleshooting.
Q7: What is the typical lead time?
A: Standard models have a lead time of 30–60 days, while custom orders may take 60–90 days depending on complexity. We can expedite for urgent projects upon request.
Q8: Can the evaporator be integrated with existing wastewater treatment systems?
A: Absolutely. Our system is designed for modular integration. We can provide complete engineering design, including pumps, piping, and control interfaces, to fit seamlessly into your current plant layout.
