The
flow scheme for water treatment using top entering mixers is as follows: flash
mixing to primary flocculator to secondary flocculator to the settling
basis. This is a in-series flow scheme. To increase the overall flow
rate capacity, a parallel in-series train is set side by side. The prior
flow scheme indicated a maximum flow rate of 2.6 MGD. The capacity was
doubled by adding a separate in-series train of flocculators, increasing the
capacity of the flash mixer and then dividing its flow between both flocculator
trains.
So adjust for a Water
Treatment Plant's specific maximum flow rate, a combination of floc basin sizes
are presented to the 15 minute detention time in each floc chamber based upon
your specific flow rate.
