A Case of Substituting Chemical Solution with Cartridge Filtration for Small Water Treatment Unit

Abstract

A small Water Treatment unit in an educational institution has been in operation for about six years, provided clean and drinking water for the inhabitants of such organization. The chemical solution process that combined with media filtration is applied for such machine. Although there was no complaint from inhabitants as the customer, the manager in charge who responsible in operation noticed that sometimes is not easy to control the technicians in carrying out its routine and periodic detail technical procedure consistently, that might influence the output quality. To make the operation easier, a few lab scale experiments are initiated due to find out whether using cartridge filtration that is still combined with media filtration could reduce their efforts. The experiments skipped chemical features and added Micro Filtration (MF) cartridge to get the lab result of output water. Reverse Engineering and Redesign is used for analyze its design aspect whereas Westinghouse approach measured its efforts in handling. The result shows that using cartridge gave a moderate quality in water composition of element content that is still in standard range of health provision; but it needed lower effort and had better aspect of design.
