Abstract

DAFRapide techniques utilising reduced flocculation times, of the order of 5 minutes, together with flotation loading rates of up to 40 m/h, can be incorporated with conventional filtration systems operating at up to 20 m/h. Product quality of typically < 1 NTU and < 0.1 NTU after flotation and filtration respectively can be achieved.
