- Abstract: We investigated the contamination of waste water from the production and recycling of plastic products and the possibility of its biological aerobic treatment in a pilot reactor with suspended biomass. By using and recycling different types of plastics, PET (Polyethylene terephthalate), LDPE (Low-density polyethylene) and HDPE (High-density polyethylene) the wastewater was divided into three categories: least, medium and the most polluted wastewater. Three pilot reactors were running for 60 days to investigate the decrease in COD and BOD5 in all three types of loading. The system was able to reduce COD of the most polluted wastewater from 810 mg / L to less than 150 mg / L and BOD5 concentration of 250 mg / L to less than 30 mg / L after 1 week of biomass adaptation. For all three organic loadings more than 84.4 % and at least 83.5 % decrease in BOD5 and COD was reached, respectively. Maximum permissible concentrations of phosphorous and nitrogen of treated wastewater from small wastewater treatment plants up to 10.000 PE were not exceeded. Furthermore, the microbial community was able to cope with sudden changes in organic loading of the pilot reactor due to recycling and fabrication of different type of plastics. Biological treatment of wastewater was shown to be a fairly appropriate technology for treating wastewater from recycling and fabrication of plastic products, although additional improvements would have to be put in place.
