Coagulants best at removing microplastics
New research has been published looking at enhancing microplastic removal from natural water using coagulant aids. Highlights Larger microbeads (1 mm – >250 μm) have >95 % removal; smaller ones (10 – <250 μm) are challenging. Denser microbeads like PVC (1.38 g/cm³) settle better than lighter ones like PE (0.97 g/cm³). PAC (0.4 mmol/L) with 3 mg/L PAM at pH 8 removes […]
