At the global outlook, providing potable water is hour of the need. The research engrossed in synthesis and evaluation of a novel nanocomposite clay filter with a keen focus on disinfection properties. Composition and volume of the clay filter were predetermined. An inlet of 105 E. coli cells was traversed via clay filter in batch and continuous mode at varied flow rates. Results revealed that in batch mode zero cell count was achieved in 20 min where as, in continuous mode within 15 min at flow rate 20 mL/min. The disruption and disparity of E. coli cells after traversing through the clay discs were confirmed by SEM technique. Rupture of the bacterial cell wall might be due to imbalance of structural morphology exerted by the positive charge of nanocomposite clay filter on the negative charge of bacterial cell wall. The research ended up with a net result that can be glorified and expanded in future.
