Results showed 91.6 was the lowest flocculating rate recorded by IH-7 (0.5mgL-1) at pH range 4-8. Moreover, IH-7 showed better flocculation performance than polyaluminum chloride (PAC) at a wide range of flocculant concentration (0.06-25mgL-1), temperature (5-45°C) and salinity (10-60 w/w). The current study found that cation addition did not significantly enhance the flocculating rate and IH-7 is a positively charged bioflocculant. These findings suggest that charge neutralization is the main flocculation mechanism of IH-7 bioflocculant. IH-7 was significantly used to flocculate different types of suspended solids such as activated carbons, kaolin clays, soil solids and yeast cells. © 2014 Elsevier Ltd. publisher: Academic Press date: 2015 type: Article type: PeerReviewed identifier: Aljuboori, A.H.R. and Idris, A. and Al-joubory, H.H.R. and Uemura, Y. and Ibn Abubakar, B.S.U.
