Management of toxic cyanobacteria in waste stabilisation ponds

Dani Barrington; Anas Ghadouani; Gregory Ivey

Abstract

Cyanobacteria and microcystins commonly occur in waste stabilization ponds (WSPs), and are a risk to human and ecological health. Although many studies have investigated their removal from batch cultures and drinking water reservoirs, few have been conducted into their removal from WSPs. Hydrogen peroxide (H2O2) has been suggested as an environmentally benign method for removing both cyanobacteria and microcystins from wastewater reservoirs. This study investigates the use of H2O2 for the removal of cyanobacteria and microcystins from WSPs, and the determination of an appropriate concentration of H2O2 to achieve this. Hydrogen peroxide was shown to decrease cyanobacterial and microcystin concentrations, and thus may be a successful algicidal treatment in WSPs.
