China ZLD Electric Heat Pump Wastewater Treatment Machine - Leading Suppliers in Vacuum Evaporators from Longhope Factory
Our solutions are applied across diverse industries: oil emulsion treatment, metal cleaning wastewater, printing & dyeing effluent, cutting fluid recycling, electroplating wastewater, and more. The technology operates on two core principles:
1. Vacuum Evaporation Principle
Lower pressure reduces the boiling point. Under vacuum conditions (-95 to -97 kPa), the boiling chamber maintains a temperature of 35–37°C. This negative pressure enables automatic suction of raw materials into the chamber.
2. Compressor System Principle
A Freon-based compressor system facilitates heating and cooling. Notably, the system eliminates the need for a feeding pump—materials are drawn into the boiling chamber, transferred to a heat exchanger, and water is evaporated. A forced circulation pump ensures continuous atomization, while the evaporation chamber’s liquid level is auto-regulated. Once concentration targets are met, a built-in device discharges the concentrated liquid.
Backed by a professional R&D team, we deliver fully customized solutions to meet unique client needs and support business growth.

Frequently Asked Questions (FAQ)
Q1: Which industries can apply your wastewater treatment solutions?
Our solutions are applied across a wide range of industries including oil emulsion treatment, metal cleaning wastewater, printing & dyeing effluent, cutting fluid recycling, electroplating wastewater, metal industry, food & beverage, and chemicals.
Q2: How does the vacuum evaporation principle work?
Under vacuum conditions (-95 to -97 kPa), the boiling chamber maintains a temperature of 35–37°C. The lower pressure reduces the boiling point of the wastewater, which enables automatic suction of raw materials into the chamber and saves energy.
Q3: How does the compressor system operate without a feeding pump?
The system utilizes a Freon-based compressor system for heating and cooling. Materials are drawn directly into the boiling chamber via negative pressure, transferred to a heat exchanger, and the water is evaporated. This design eliminates the need for an external feeding pump.
Q4: How is the concentrated liquid discharged?
A forced circulation pump ensures continuous atomization while the liquid level in the evaporation chamber is automatically regulated. Once the concentration targets are met, a built-in device automatically discharges the concentrated liquid.
Q5: What information is required to get a tailored quotation?
To provide an accurate quotation and customized solution, please share details about your wastewater type, daily treatment capacity, testing data, and desired treatment outcomes.
