turbidity water treatment and turbidity water filtration in canada
Cationic polyacrylamides modified with fluorinated methacrylate (FPAM) were prepared with acrylamide, dodecafluoroheptyl methacrylate (DFM) and methacryloxyethyl trimethylammonium chloride by free radical micellar copolymerization. The solution properties of FPAM were investigated. The results show that there are strong hydrophobic associations in the FPAM aqueous solution.
Thus, the cationic polyacrylamides would only have a minimal effect on removing water from the gel formed by the TB-EPS around the sludge particles. This led to inferior flocculation performance which was later replicated in the poorer dewatering performance (see Table 5 ).
