摘要: The efficiency of particle settling in tube settlers can be improved by reducing diameter; however, this has limits due to the clogging at low diameters. In study, effect reduced diameters on enhanced was investigated. This improvement achieved staging operation and diameter last stage multi-stage settlers. Theoretical analysis indicated that would improve if were used different stages series their stage. predictions from theoretical tested a pilot study. Oneand two-stage settler plants remove water turbidity caused clay first second phases tests with without adding coagulant, respectively. one-stage 5.0 cm, those 1.2 results both showed more efficient than for removal no observed because majority particles had been removed
