Combined Iron-Loaded Zeolites and Ozone-Based Process for the Purification of Drinking Water in a Novel Hybrid Reactor: Removal of Faecal Coliforms and Arsenic

This study was carried out to provide a novel solution treat drinking water at household levels, specifically removing arsenic (As) and faecal coliforms (microbes). In the current investigation, synergistic iron-loaded zeolites ozonation process (O3/Fe-ZA) used for first time in modified batch reactor remove coliform bacteria tap water. Moreover, utilizes human health risk assessment model confirm due As intake The revealed threat among residents suffering from adverse effects of through its Furthermore, results also suggested that O3/Fe-ZA significantly removes As, when compared with single processes. Additionally, ozone dose 0.2 mg/min Fe-ZA 10 g (in process) gives maximum removal efficiency 100% within 15 min removal. 30 min, 88.4% achieved 0.5 93% using process. Hence, it concluded may be regarded as an effective method
