AVAILABLE MODELS AND MAIN TECHNICAL CHARACTERISTICS

We supply six different models of forced circulation evaporators depending on the stream, capacity and energy required. Starting with the ENVIDEST MVR FF all the way to the ENVIDEST MFE 3 for the highest capacity of them all to treat large volumes of wastewater.

Forced circulation evaporators offer high efficiency in liquid-waste management thanks to their low energy consumption. They also allow treatment of industrial wastewater that cannot be treated with conventional technologies due to effluent complexity.

They are especially indicated when the effluent contains fouling substances, viscous liquids, crystals or other components preventing natural circulation.

OPERATION OF OUR FORCED CIRCULATION VACUUM EVAPORATORS

1

Startup & fill up

When the evaporator is switched on, the loading valve opens and the product starts to fill the vessel's chamber.

2

Forced circulation

Once the level is reached, the recirculation circulation pump is activated to create a constant liquid flow across the heat exchanger and its corresponding vessel, guaranteeing effective heat transfer and handling complex streams that would otherwise quickly scale or suffocate the process.

3

Circuit Heating

For thermal evaporators, either saturated steam or hot water gets routed through the jackets to reach operating temperature.

Electrical evaporators use a series of electrical resistors within the vessel to achieve the same result.

4

Circulation & condensation

Once the whole circuit has reached operating temperature, the vapors from the vessel when routed through heat exchangers and condensed to retrieve the distillate. Heat is recovered during the processed, heating the new product brought in to refill the vessel.

The following is a 3D video animation that shows step-by-step how our multiple effect evaporators work.

CONFIGURATIONS

We offer forced circulation evaporators in both thermal and electric energy options, as well as one, two, and three effects to adapt the solution to each client’s capacity, energy availability, and budget constraints.

Thermal energy works well for high volumes and when it is readily available as excess heat, and electric is more flexible and efficent for many flows and floorpan constraints.

Single-effect units are ideal for lower flows or when simplicity and lower CAPEX are priorities, while additional effects significantly reduce energy consumption by reusing latent heat.
