Modifications to the Slow Sand Filtration Process for Improved Removals of Trihalomethane Precursors

Abstract

Establishes, by pilot-plant testing of media characteristics and pretreatment schemes and full-scale sampling, the optimal capabilities of slow sand filtration to remove THM precursors in small systems. Also characterizes removed organic matter and microbial populations, determines the process's cost-effectiveness for varying raw water conditions and design parameters, and compares THM-removal performance of slow sand filtration with that of the rapid-rate process. Published in 1989.
