Many steps in plastics processing involve the use of water, which is then contaminated. For example, thermoplastics are processed using heat and release agents. The extruders used here are cooled by water – and hydraulic oil can get into it. In the production of plastics (polymers), water is often used as process water, which is contaminated with the starting materials (monomers, oligomers) and cannot be discharged into the sewage system without further treatment. Another example is the vulcanisation process, in which wastewater is also produced. Synthetic rubbers are vulcanised under pressure and with the help of hot steam to ensure dimensional stability. The resulting condensate requires treatment, too.

What solutions does OKO-tech offer for this wastewater?
OKO-aquaclean flotation systems are used to separate oil and separating agents from wastewater in an energetically advantageous way. After coagulation of the finely dispersed particles and droplets, these are removed from the wastewater by flotation.
