Vacuum Distillation System
Simply the act of separating water from contaminants.
Water reaches its boiling point and is evaporated away
leaving the non-vaporized substances behind. HF’s pollution
control system’s evaporate the water in a vacuum reducing
the boiling temperature to below 100 degrees F (38 °C).
Vacuum Distillation System separates the water solvent
from chemical waste solutions discharged from metal
plating, photographic processing, printing ink, paint
manufacturing, cosmetic, mechanical and other industries
which utilize water-based chemicals.
For example, in photographic processing applications,
the evaporators separate as much as 95% of the water,
leaving a pumpable concentrate representing only 5%
of the total solution processed. After separation, the
concentrate is removed from the processing facility
by a hazardous waste collector who either destroys the
waste or reprocesses it into other usable products.
The pure water can then be discharged into municipal
sewer systems or further refined for reuse.
The Vacuum Distillation System allow for low energy
consumption, reduced water usage and sewer costs, as
well as lower waste pickup charges. The application
dramatically offsets the high cost of hazardous waste
chemical disposal and will assure compliance with local
and federal EPA requirements.
