Abstract:
1. A skimmer system attached to a tank having fluid therein, the fluid in the tank defining a tank fluid surface, the system comprising: a) a reservoir to receive fluid from the tank, the fluid in the reservoir defining a reservoir fluid surface, the level of the reservoir fluid surface being maintainable below the level of the tank fluid surface; b) an inlet defining an inlet edge, the inlet being positioned adjacent the tank to transfer the fluid from the tank to the reservoir, the inlet edge being located below the level of the tank fluid surface; c) an inlet surface disposed between the inlet edge and the reservoir; d) a reservoir pump connected to the reservoir to transfer fluid from the reservoir to the tank; and e) a weir defining a weir edge, the weir being maintained substantially gapped above the inlet surface to allow particulate in the fluid to pass under the weir when the reservoir pump is activated and the weir edge is maintained substantially below the level of the tank fluid surface to prevent particulate on the fluid from passing under the weir when the reservoir pump is deactivated.
