文摘
- •
Coagulation performance could be improved by the addition of cationic polyelectrolyte: epichlorohydrin–dimethylamine (DAM-ECH).
- •
Floc growth rate and size was enhanced by the addition of epichlorohydrin–dimethylamine.
- •
Floc strength was enhanced by PTC-DAM-ECH (PTC added to DAM-ECH) in pH 4–9, but was only enhanced by DAM-ECH-PT (DAM-ECH added to PTC)C when pH < 6.
- •
Floc recovery ability was only improved by PTC-DAM-ECH.
- •
Membrane fouling was reduced by the addition of DAM-ECH, especially DAM-ECH-PTC.
