Solution: Thermal evaporator model ECO DPM3

Advantages: Recovery of the distillate in the production process, reduction of disposal costs by more than 20 times, energy efficiency thanks to the hot water supplied by a cogenerator.

2

Vacuum evaporation in the pharmaceutical industry

Process: Drug and vaccine production.

Waters to be treated: washing waters of mixers and reactors containing active ingredients and other complex organic molecules.

Challenge: need to remove APIs present in the waters for discharge.

Solution: Thermal evaporator model ECO DPM2

Advantages: Removal of active ingredients and other complex molecules by over 99%, distillate quality suitable for both discharge and reuse, automated management.

3

Vacuum evaporation in the detergent and cosmetics industry

Process: Production of cleaning and personal care products.

Water to be treated: Washing waters containing surfactants and various organic substances.

Challenge: reduction of excessively high disposal costs.

Solution: Mechanical vapor recompression evaporator model ECO CMV.

Advantages: Reduction of disposal costs by more than 10 times, total elimination of surfactants, obtaining a high-quality distillate suitable for both discharge and reuse.

4

Vacuum evaporation in die casting

Process: aluminum die casting

Water to be treated: Emulsions with release agent

Challenge: Need to reduce disposal costs and achieve total recovery of treated waters.

Solution: Thermal evaporator model ECO DPM3

Advantages: Distillate recovery over 95%, reduction in disposal costs, reduction in the amount of water drawn from the network. Extremely simple evaporator management and minimal maintenance.

5
