Carbon membrane for water treatment

The objective of this study is to prepare and characterize carbon membranes, assess their filtration performance and compare the performance with commercial products. The preparation of the carbon membrane involves coating a slurry of powdered activated carbon mixed with binder on biomass fly ash filter supports. The characterization will be carried out by studying the pore profile, morphology, hydrophilicity, permeability etc. Filtration performance will be assessed by using model feed solutions containing contaminants such as E coli, polysaccharides, humic acids, phenol. The flux, contaminant rejection, fouling and ease of cleaning will be the parameters used to measure the membrane suitability and efficiency. The performance will be compared with existing commercial products such as Aquasure gravity filters and Aquaguard UV.
