Full textThe removal of nanoparticles (NPs) from waters is a serious challenge in the water treatment field owing to the high stability and colloidal nature of particles. This study is devoted to develop effective flotation processes for NP separation. The investigation is firstly conducted to get a good knowledge of features and colloidal behaviors of NPs in suspension. Surface modification tests and adsorption-aggregation experiments are then carried out to understand the interaction mechanisms between NPs and flotation assisting reagents. Two types of flotation (dissolved air flotation (DAF) and colloidal gas aphrons (CGAs) involved flotation) were specially focused on: the former aims at using air bubbles to remove NP aggregates with the assistance of humic acid (HA), while the later employs the surface functionalized microbubbles, CGAs, to enhance the interaction of NP-bubble for the sake of high treating efficiency. Results show that, on mixing with the highly basic HA solution (pH12.9), the surface charge of TNPs is primarily neutralized by and then screened by polyanions of HA. When the pH of TNP-HA suspension is lower than 3 by adding HA stock solutions at pH4.0~9.0, the electrostatic attraction between TNPs and anions becomes insufficient but the aggregation of TNPs-colloidal HA occurs. In continuous DAF trials, the appropriate pH of HA stock solution (pH ≦ 9) and optimum HA concentration (11.1 mg/L DOC) for high TNP removals (> 95 %) are determined. The residual HA concentration remained in a low level even when HA is overdosed. When the pH of the TNP-HA suspension is highly acidic, most HA molecules are not really soluble and uncharged, and they may aggregate themselves and form hydrophobic colloidal precipitates to minimize the contact with the aqueous environment. As for the study of CGAs, the characterization results denote that introducing air flow during the CGA generation process can slow down the liquid drainage speed and may facilitate the particle separation performance; the stirring speed is a crucial parameter to create micron scale bubbles, and CGAs can be positively or negatively surface charged by using different surfactants. Different SiO2 NP (SNPs) can be efficiently separated from aqueous suspensions by the continuous CGA generation-flotation process with the highest SNP removal close to 100 %. The comparison tests between CGA-flotation and DAF denote that the former take the greater advantage because of its better treating effect and less surfactant demand
