Metallic parts must be cleaned after they have come into contact with cutting oils and cooling lubricant emulsion during machining. Oils, greases and dirt particles are washed off the surfaces of the components, which end up in the wastewater during production. Not only oils and greases, but also more aggressive chemicals are used in mechanical engineering and plant engineering. For example, hydrochloric and sulphuric acid or alkalis are used when pickling stainless steel or aluminium. These substances can also get into the wastewater during the subsequent rinsing processes.

What solutions does OKO-tech offer for this wastewater?
Wastewater containing emulsions and oils can be treated by demulsification in OKO-aquaclean emulsion breaking systems. Neutralisation and heavy-metal precipitation of acidic rinse water from pickling processes take place in physico-chemical WWTPS. Depending on the type and quantity, dewatering containers and chamber filter presses are used to dewater the sludge.
