Abstract：
:Previous research has shown that dosing polymers directly to the saturator of a dissolved air flotation (DAF) process in replacement of upstream coagulation can achieve algae removal comparable to that of conventional treatment, as a result of bubble modification. In this paper we further explore the application of polyDADMAC as a bubble modifier in this adapted DAF process. It was determined that removal improved with increasing polyDADMAC molecular weight (MW). Removal efficiencies obtained for Microcystis aeruginosa were much greater than those predicted theoretically, and were attributed to a potential projection of the polymer into the aqueous phase, increasing the swept volume of the bubble. PolyDADMAC dose and the resultant removal efficiency were dependent on the character of the associated algogenic organic matter (AOM). The AOM with high MW, low charge and significant hydrophobicity and protein content enabled co-operative binding, while that of high charge and low hydrophobicity hindered attachment.
