Floc Strength Characterization Technique. An Insight into Silica Aggregation

Hermawan, Mandalena; Bushell, G; Craig, Vincent; Teoh, Wey Yang; Amal, Rose


This paper tests an approach to the estimation of relative particle bond strength based on the nondimensional floc and aggregation factors. The strength of flocs formed by aggregating nanosized silica particles with the addition of potassium chloride (KCl) or cationic surfactants, alkyltrimethylammonium bromide (mixture of CTAB, DTAB, and MTAB) was analyzed. The bonding force of the flocs formed in surfactant compared to that formed in the KCl system was estimated using the new dimensional...[Show more]
