Ozone Application in Recirculating Aquaculture System: An Overview
TL;DR: Ozone is used in RAS as a disinfectant, to remove organic carbon, and also to remove turbidity, algae, color, odor and taste, but the effectiveness of ozone treatment depends on ozone concentration, length of ozone exposure (contact time), pathogen loads and levels of organic matter.
Phosphorus adsorption on water treatment residual solids
TL;DR: In this article, the authors examined water treatment residual solids (WTRSs) from four North American water treatment plants to determine the role that coagulant types play in phosphate adsorption.
Direct Biofiltration for Manganese Removal from Surface Water
TL;DR: In this article, a bench-scale direct bio-filtration was used to remove manganese and dissolved organic carbon (DOC) from a pH 6 surface water source in Halifax, Nova Scotia, Canada.
