Abstract:a b s t r a c tThe ballasted flocculation (BF) process is widely used in the water treatment process to cope with climate change. Microsand and magnetite are commonly used, which act as a seed in ballasted floc. The recovery of the ballast in BF process can affect the operating cost. In this study, we evaluate various sizes of magnetite particle with a specific gravity of above 5 in order to apply the hydrocyclone as a ballast recovery system in the BF process. The conventional purpose of the hydrocyclone is t… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
