Design and construction of a powdered chlorine mixer :

Abstract

Water is a vital natural resource which forms the basis of all life, while water is readily available in developed countries, in developing countries more than 1.2 billion people do not have access to a safe and adequate water supply. For water to be made safe, chlorine has to be added to it so as to disinfect it, if it is powdered, then it has to fast be liquified before use. However, the manual mixing mechanism used portray challenges to the workers and water consumers, the effects of chlorine have been felt by very many people involved in mixing powered chlorine with water (manual mixing). The main objective of this project was to design and construct a powdered chlorine mixer for easing the chlorination process in Water works village in Tororo and the specific objectives were; To design the components of the machine, to construct & assemble the components of the machine, to test the machine and to carry out economic analysis or the prototype. Literature review discusses; properties, forms and desired characteristics of chlorine, available mixing mechanisms, motor selection for use, economic analysis, water treatment review, brief history of chlorine mixers, how chlorine mixing is done in Tororo and the proposed system. Methods used in data collection included desk study, oral interview, consultations and discussions. The design sketch was done using AutoCAD and the machine was constructed. Therefore, this research was done for the purpose of designing and constructing a powdered chlorine mixer and with the help of this chlorine mixing machine the time gap is reduced, efficiency of chlorine mixer is increased and labour costs are reduced. Keywords: chlorine mixer, chlorine, manual mixing, powdered chlorine and water.
