Filtration of Giardia cysts and other substances. Volume 3, Rapid rate filtration
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 removals were evaluated by means of a lab-scale pilot plant at temperatures of 4°C and 18°C, for low turbidity water, at hydraulic loading rates of 8 cm/min (2 gpm/ft2, 24 cm/min (5 gpm/ft2) and 33 cm/min (8 gpm/ft2), 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 ...
