The best PVC separation (90% recovery) from the other three plastics was accomplished through flotation at 40 °C at 200 and 240 rpm in a small (0.35 L) and medium (3.0 L) glass flotation cells, respectively. Ozonation was conducted for 10 min by introducing ozone gas (90–150 mg-O 3 L −1) at 50 mL min −1 flow rate.
