Electric Automatic Vacuum Distillation Low Temperature Sodium Chloride Sodium Sulfate Evaporator Crystallizer Machine System

As an integrated equipment for efficient wastewater treatment and resource recovery, the low-temperature evaporator relies on advanced low-temperature evaporation technology to accurately separate moisture and pollutants in wastewater, achieving the dual goals of wastewater reduction of ≥90% and resource recycling. It is widely used in chemical, food, electronics, electroplating and other industries to build a solid environmental protection line for the sustainable development of enterprises.

For this site typical industrial wastewater such as cutting fluid and polishing cleaning wastewater, an integrated process of pretreatment + low-temperature evaporation concentration + deep purification is used. Longhope's model V-HP-SF-10000 is used, with a daily processing capacity of 10 tons. The effluent water quality fully meets the emission standards and can be directly discharged or recycled, significantly reducing the company's water consumption and environmental protection costs.

Whether it is high concentration, high salt, heavy metal wastewater, valuable solution recovery, or zero wastewater discharge requirements, the equipment can be accurately adapted:​

High-concentration refractory organic wastewater: cutting fluid, emulsion, electroplating/metal surface treatment wastewater, die-casting/grinding and polishing wastewater, coating wastewater, landfill leachate membrane concentrate, high COD wastewater, release agent wastewater, laboratory wastewater, etc.;​

High-salt wastewater: RO reverse osmosis concentrated water, high-salt and high-COD wastewater, MVR/multi-effect evaporation mother liquor, chemical wastewater, spray waste liquid, desulfurization and denitrification spray waste liquid, etc.;​

Heavy metal wastewater: evaporation and concentration treatment of chemical nickel waste liquid, zinc-nickel alloy wastewater, copper-containing wastewater, etc.;​

Valuable solution recovery: Evaporation, concentration and crystallization of ferrous sulfate process solutions, food industry process solutions, precious metal concentrates, etc., to efficiently recover valuable concentrates or crystallized salts;​

Zero Wastewater Discharge (ZLD): As the core treatment unit for heat-sensitive and difficult-to-treat wastewater, it ensures the stable operation of subsequent crystallization and helps enterprises achieve environmental protection upgrades.​

Machine Advantages:

The treatment effect is excellent: the waste liquid is concentrated and reduced by more than 90%, the effluent is clear and translucent, and the discharge/reuse is pressure-free when it meets the standards;​

Extreme energy saving and consumption reduction: only electric energy is required to drive, and the power consumption of processing 1 ton of waste liquid is about 100 kilowatt-hours, which is significantly lower than the energy consumption of traditional equipment;​

Fully automated operation: Equipped with Siemens PLC control module, no manual supervision is required throughout the process, the operation is simple and the operation is stable;​

Extremely low maintenance costs: Adopting mature principles of industrial air conditioning, core parts are easily available in the market, and subsequent maintenance is convenient and cost controllable;​

Ultra-long service life: The core components are selected from international head brands, with reliable operation and a service life of more than 10 years;​

Outstanding safety performance: In a vacuum and negative pressure environment, the material liquid can boil at about 35°C, and there is no safety hazard in low-temperature operation;

Small footprint: integrated design of vacuum, evaporation and cooling, compact structure.​

One machine is multi-purpose and flexible: it can handle a variety of industrial wastewater such as cutting fluid, chemical nickel waste liquid, high-salt wastewater, etc. within the allowed range, adapting to the needs of multiple scenarios;​

Customized solutions: Tailor-made equipment and processes according to the customer’s incoming water quality, water capacity and discharge standards to accurately solve individual needs;​

Precise material adaptation: Recommend exclusive materials for different wastewater characteristics to ensure equipment stability.
