Restricted Flow of Hypochlorinators

Abstract

Towns in Honduras were using our dosing mechanism (the constant head tank) for use with chlorine for disinfection. Some of these hypochlorinators were experiencing diminished flow rates which made dosing difficult. It is believed that the clogging is due to the precipitate of chlorine solution, calcium hypochlorite. The set up of the experiment consists of a stock tank, constant head tank, and a peristaltic pump which determined the flow rate. The procedure included allowing the solution to settle, filtering it through a cloth rag and changing the angle of the float valve to minimize exposure to atmospheric CO2 gas. From the research, it appears that steps such as the proposed procedure may be taken to reduce the detrimental effects of calcium carbonate precipitate on the hypochlorinators.
