Workpieces are wetted by cooling lubricants, by greases, oils and other contaminants during shaping, such as turning and drilling.
Before the workpieces are further treated, e.g. painted, they must be cleaned.
The workpieces are cleaned in washing systems using superheated steam and soap-like washing lyes, so-called surfactants.
In the washing system, the soiled components first pass through the washing zone, then the rinsing zone, then the compressed air zone for blowing off, and finally the drying zone.
The washing solution, superheated steam, rinsing water, blow-off compressed air, and drying hot air are fed to the washing system.
Spent rinse water remains in the circuit and is recycled into the wash solution.
The exhaust air from the drying zone and the spent wash solution must be removed from the wash system.
The dirt-laden wash liquor is discharged to a wastewater treatment plant.
Washing systems using toxic cold cleaning liquids are no longer appropriate due to effects that are hazardous to health and the environment.
