Solar Cell as Energy Chlorinator for Disinfection of Flowing Water

Abstract

The provision of clean water for the community must pay attention to physical, chemical and bacteriological requirements and this is intended to avoid negative impacts that are detrimental to its use. The purpose of this research is to produce a solar cell device as a chlorinator energy used to disinfect running water for the needs of the community. Experimental research to determine the performance of the tool to produce residual chlorine and E. coli in flowing water with variations in distance of 0 m, 0.5 km and 1 km according to the standards of the Ministry of Health 32/2017. The results of the research using a chlorinator consisting of a solar cell, battery, modem internet system, equipped with a signal lamp and relay lamp, a peristaltic pump as an injection of chlorine solution and a disinfectant used as a chlorine solution. The need for chlorine is 1.63 mg/l (141 g/day) dissolved in 40 l, then peristaltic pump discharge: 28 ml/minute for disinfection at reservoir water discharge 1.13 l/s, the result is: residual chlorine on average at a distance of 0 km, 0.5 km and 1 km respectively 0.64 ppm, 0.49 ppm and 0.3 ppm and contains E coli (0 per 100 ml), except for replication 11 which is 2 per 100 ml and still meets the requirements clean. The chlorinator can be used but it still needs to be tested regarding the durability of the components, the manufacture of digital devices, namely pump discharge, control switch internet system, automatic signal in case of trouble.
