Dear Mr. Asanka
The detail analysis of effluent is required. You have mention that BOD of effluent from plastic recycling is zero. It means COD is contributed by non biodegradable organic & reducing inorganic chemicals. It means no biological treatment can remove non biodegradable compounds from effluent.
The probable answers are as below.
a. Soluble & colloidal non biodegradable organic compounds – Flocculation, sand Filtration and & activated carbon filtration can give the good result
b. Soluble reducing non biodegradable – Mostly inorganic – RO will be the only alternative.
c. Insoluble / colloidal non biodegradable organic & inorganic – Flocculation, Sedimentation, Sand filtration and Activated carbon filtration.
More alternative can be developed. For details please contact at rvsveipl@gmail.com
