| Abstract | The objective of this study was to investigate the use of anthracite and sand media as a means for increasing the capacity of rapid sand filters at the Sam Sen Water works in Bangkok. Model filters were designed and constructed for treatment of coagulated and settled water at the Sam Sen Plant using different combinations of sand and
anthracite. On the basis of filtered water turbidity,
headloss rate, and behaviour of anthracite in backwashing, the most suitable anthracite-sand combination was 49 cm of 0.833-1.397 mm nominal size anthracite and 31 cm of
0.495-0.833 mm nominal size sand. This system gave filter runs of 54 hr and 18.6 hr at filtration rates of10 and 15 m3/ms.hr and produced 540 m3 and 279 m3 of filtered water per m2of filter area, respectively |
