Development and Optimum Composition of Locally Developed Potable Water Treatment Tablets
Journal Title: Leonardo Electronic Journal of Practices and Technologies - Year 2009, Vol 8, Issue 14
Abstract
Current high level of energy cost and operational cost of membrane technologies and couple with difficulties in obtaining chemicals for potable water treatment give rooms for development of local substance and low cost adsorbents for water treatment. This paper presents a follow-up study on an earlier work in which some water treatment Tablets were produced and tested. The current work was directed at establishing the optimum composition of the tablets. Alum, calcium hypochlorite and lime were combined in proportion and made into pastes and tablets. Residual chlorine contents of the tablets were determined. The quality of stream water samples treated with the tablets was measured by chlorine content, pH and turbidity removal. It is concluded that the best composition is one part alum, two parts hypochlorite and three parts lime and this produced treated water pH of 7.8, chlorine residual of 5.0 mg/l and settled water turbidity 3.0 NTU. The product is aimed for use in rural communities to reduce rampaging death from water borne diseases.
