Wastewater treatment for plastics processing ensures that production wastewater from different manufacturing stages is properly treated in accordance with environmental and operational requirements. In thermoplastics processing, release agents are used, while extruders are cooled with water, which can result in hydraulic oil entering the cooling water. Process water from polymer production may also contain monomers or oligomers and therefore requires appropriate treatment before discharge. In the vulcanisation of synthetic rubber, condensate is generated that may also require treatment.

Separation of Oil, Release Agents and Fine Particles from Plastics Processing Wastewater
For wastewater treatment in plastics processing, OKO-tech uses OKO-aquaclean Flotation Systems. First, coagulation binds finely dispersed particles and droplets. The subsequent flotation process separates oil, release agents and suspended solids from the wastewater. This improves treated-water quality and can enable the water to be reused or discharged in accordance with the applicable requirements.
Wastewater Treatment Solutions for Plastics Production
Different wastewater streams can arise depending on the plastics manufacturing process. OKO-tech uses treatment systems designed around the requirements of the respective production process. The combination of coagulation, flotation and physico-chemical treatment processes enables targeted treatment of highly contaminated wastewater with optimised energy consumption.
This approach can be used to treat condensate from vulcanisation processes as well as cooling and process water, helping plastics manufacturers meet their operational and regulatory requirements.
