High quality effluents suitable for crop irrigation can be produced by lime and Clarifloc treatment of raw domestic wastewater: in laboratory jar-test experiments the average percentage removals were 99.999 for faecal coliforms, 99 – 99.9 for salmonellae, 99.9 – 100 for total parasites and 99 – 99.9 percent for rotavirus. The average removals of COD and suspended solids were 79 – 87 and 97 percent respectively. Clarifloc treatment was marginally better than that achieved by lime.
