Abstract
Coagulants are an essential part of a water filtration plant as well as a signifiant operating cost. Therefore, it is very important that they be used as effiently as possible. This semester, the Coagulant Management team has calculated and analyzed the relationship between PACl density and concentration that was ultimately used in calculations necessary for centrifugal pump parameters and for hydrometer recommendations. In addition, the team brainstormed fabrication ideas for the coagulant injection point. The centrifugal pump was partially fabricated, but because of the density vs. concentration relationship calculated, the pump, once fully fabricated, can be tested using PACl. In addition, the Coagulant Management team has recommended the testing and use of a plastic (polycarbonate) hydrometer from Krackeler Scientific Inc. with a specific gravity range between 1.000 and 1.220.
