Abstract |
The efficiency of rapid rate filtration for removal of Giardia lamblia cysts, standard plate count bacteria, total coliform bacteria, and turbidity was determined experimentally under a wide range of operating conditions. Percent removal was evaluated by means of a lab-scale pilot plant at temperatures of 4C and 18C, for low turbidity water, at hydraulic loading rates of 8 cm/min (2 gpm/sq ft), 24 cm/min (5 gpm/sq ft) and 33 cm/min (8 gpm/sq ft), for 'in-line' filtration, for three filter media, and using three chemicals. Testing was performed also using a 1.3 L/s (20 gpm) field-scale rapid rate filtration pilot plant. The range of testing was narrower and focused on ascertaining the findings at the lab-scale. The results showed that rapid rate filtration will effectively treat low turbidity water, and will remove Giardia cysts if proper chemical pretreatment is used. |
