ABSTRACT:
A liquid filter assembly is provided of the type having a container, a liquid inlet, a liquid outlet and a filter medium adapted to operate in conjunction with a filtration aid such as diatomaceous earth. The filter medium is of the type which the filtration aid falls off at the end of a cycle and becomes mixed with liquid and redeposited on the filter medium at the commencement of a new cycle. The liquid inlet has a cowl directed downwardly and at the incline to a radius of the container in plan view to direct incoming fluid towards the bottom of the container to properly distribute filtration aid from the container bottom.
