Combined Effect of Water Purification Processes on the Removal of Histoplasma capsulatum from Water

Abstract
Kansas River water, sterilized in the autoclave and seeded with the mycelial phase of Histoplasma capsulatum, was subjected to conventional water purification processes of plain sedimentation, coagulation, settling, rapid sand filtration and chlorination applied in sequence. These combined processes removed all viable spores before chlorination. This indicates that the combined processes produce a water supply free from H capsulatum. The membrane filter technique was found to be suitable for use in this laboratory studv.
