Abstract
A filtration unit contains a plurality of filter housings each filter housing having a cylindrical shell with a lower port an upper port and a filter element. The lower and upper ports direct fluid through the filter housing in a first direction during a filtering cycle and direct fluid through the filter housing in a second direction during a backwashing cycle. The unit also includes a diverter and a servomechanism that rotates the diverter to selectively connect the filter housing to a drain port for the backwashing cycle.
