Flocculation of Harmful Algal Blooms by Modified Fly Ash

Article Preview

Abstract:

The flocculants of fly ash(FA) and modified fly ash (mFA)were investigated in this study to evaluate their flocculation efficiencies in freshwater containing harmful algal blooms(HABs). The experimental results show that the efficiency of flocculation can be prominent improved by mFA.It was found that the fly ash modified by hydrochloric acid could form network structure bundle, algal cells were wrapped up through netting and bridging effect. So the method that removal of HABs with modified fly ash is low cost with high efficiency
