A vacuum distillation system by H2O GmbH has reduced the amount of wastewater produced and saved more than €100,000 ($108,280) annually for thermofin, a German metalworking company.
Bernd Löffler, general manager at thermofin, says the investment paid for itself in just one year, delivering savings by eliminating wastewater and disposal costs.
H2O GmbH says depending on the level of contamination, its Vacudest vacuum distillation systems evaporate 100 percent wastewater to produce 98 percent pure water, leaving only 2 percent residue. The company says by recycling wastewater this way, customers can reduce disposal costs by up to 98 percent.
The company says what sets Vacudest apart is the patented technologies from the application center for wastewater-free technology that guarantee consistent distillate quality. The distillate is virtually free from oils, making it optimally suited for reuse, even in demanding processes.
Any company generating more than 180 cubic meters of wastewater each year can save money, according to H2O GmbH. Oily cooling lubricant emulsions, die-casting release emulsions and rinse water used in cleaning parts and in surface treatment processes can be treated, to name just a few examples.
