As a leading manufacturer from Qingdao Conqinphi Environmental Technology Group Co., Ltd., we are proud to introduce our Semi-Automatic Vacuum Evaporator for Wastewater, constructed from high-quality 304 Stainless Steel. Designed for efficient wastewater volume reduction, this unit operates at 220V with a processing capacity of 300 liters per hour and a low power consumption of 0.75kW. Our factory, spanning over 10,000 square meters, ensures rigorous quality control and reliable production since 2015, serving global markets across North America, Europe, Asia, and more.
This evaporator utilizes vacuum evaporation technology to separate water from contaminants, producing clean distillate and concentrated waste. The semi-automatic design balances ease of operation with cost-effectiveness, making it ideal for small to medium-scale industrial wastewater treatment. Below we detail its key features, technical specifications, and benefits.
Key Features & Advantages
- 304 Stainless Steel Construction: Corrosion-resistant and durable, suitable for handling various wastewater types including acidic or alkaline streams.
- Vacuum Operation: Low boiling point under vacuum reduces energy consumption and minimizes scaling, extending equipment lifespan.
- Semi-Automatic Control: Simple interface with automatic vacuum and temperature monitoring, while allowing manual adjustments for flexibility.
- High Efficiency: 300L/H capacity with only 0.75kW power input, achieving a low energy-to-water ratio (approximately 2.5 kWh per 1000 liters).
- Compact Footprint: Space-saving design suitable for limited floor areas in factories, labs, or municipal facilities.
- Low Maintenance: Few moving parts, easy cleaning, and optional CIP system available upon request.

Frequently Asked Questions (FAQ)
-
Q: What type of wastewater can this evaporator handle?
A: It is suitable for a wide range of industrial wastewater including metalworking fluids, coolants, emulsions, landfill leachate, chemical solutions, and rinse water. For highly corrosive or specific streams, we recommend consulting our engineers for material compatibility. -
Q: Is the 220V power supply sufficient for continuous operation?
A: Yes, the unit is designed to operate on standard 220V single-phase power. The 0.75kW motor and heater are optimized for this voltage, ensuring stable performance. Three-phase options are available upon request. -
Q: How much space is required for installation?
A: The evaporator has a compact footprint (approximately 1.2m × 0.8m). A clearance of at least 0.5m around the unit is recommended for maintenance and ventilation. Exact dimensions can be provided in the technical drawing. -
Q: What is the typical distillation quality?
A: The distillate typically has a conductivity of less than 50 µS/cm and a TDS under 30 ppm, making it suitable for reuse or discharge. The actual quality depends on the feed water composition. We can provide a lab test report upon request. -
Q: Does the semi-automatic control require constant supervision?
A: No, the system automatically maintains vacuum and temperature setpoints. However, due to the semi-automatic nature, an operator is needed to start/stop cycles and occasionally monitor the process. Full automation (PLC + HMI) is available as an upgrade. -
Q: What maintenance is required?
A: Routine maintenance includes cleaning the evaporator chamber and heat exchanger every 2-4 weeks depending on scaling tendency. The vacuum pump oil should be checked periodically. Detailed maintenance schedule is provided in the manual. -
Q: Can the capacity be adjusted for smaller batches?
A: Yes, the unit can operate at lower feed rates (e.g., 50-100 L/H) by adjusting the feed pump speed. However, the minimum stable operation is about 20% of the rated capacity. For very small batches, we recommend our lab-scale models. -
Q: What certifications does your company hold?
A: Our company is accredited with ISO9001, ISO14000, ISO45001, and other management system certifications. Our manufacturing processes comply with international standards. Specific product certifications can be discussed based on your target market.
