1. A rotating belt filtration system comprising:
a container (100);
a sump (240) external to, and elevationally lower than the container (100);
an endless, inclined, rotating filter belt (130) disposed within the container (100) dividing the container (100) into an upper influent basin (120) and at least one filtered liquid basin (210) for receiving filtered liquid (200) which has passed by gravity through the rotating filter belt (130);
a lower collection basin (170) beneath the filtered liquid basin (210) and in fluid communication with a drain line (300A) for draining accumulated liquid from the lower collection basin (170) of container (100) into the sump (240);
an outflow pipe (220) permitting egress of filtered liquid (200) from the at least one filtered liquid basin (210); and
a pump (230) located in the sump (240) having a recirculation pipe (250a) attached thereto wherein the recirculation pipe (250a) is also attached to a connector (260) on the container (100) for delivering recirculated fluid to the upper influent basin (120).
