Coolant emulsions or lubricants can be treated by Turbevap wastewater evaporator. The vapor can be condensed and distilled from the used coolant emulsions wastewater itself. Concentrated residues heavy metal compounds will be deposited, meanwhile, the water will evaporate and escape into the condenser until there is no more water in the wastewater. The vapor after being extracted and condensed can be reused again for production processes as clean water.
