In traditional machining workshop, coolant emulsions are often contaminated with heavy metals and additives, so they would not be reused, but discharged into the environment with other wastewater sources. When they are used, coolant emulsions are often stored for further elimination by specialized company. As the cost of coolant emulsions increases with more and more stringent wastewater regulations, concentrating emulsions becomes a necessity in modern workshops.
Used emulsions can be treated with the wastewater evaporator Turbevap. By distilling efficiently these emulsions, oils and other metalic contaminants are concentrated while the distilled water can be valued. Concentrated residue respresents less than 5% of the initial used emulsion volume. This allows industrial companies to reduce by nearly 95% the elimination cost of used emulsions while reducing greatly water consumption.
