Abstract
A floating pond skimmer is coupled by a fluid conduit to a remote filter/aerating apparatus. The skimmer sucks a mixture of solids and water, grinds/chops the solids, and pumps the reduced solids and water through the conduit to the filter/aerating apparatus which separates the solids from the mixture and aerates the water from the mixture. The floating skimmer preferably includes a vortex chamber, an on-board pump with a grinding impeller, an adjustable ballast, and an anchor. The filter/aerating apparatus includes an inclined screen and a drain tray beneath the inclined screen coupled to a water discharge conduit. Optionally, an aeration pump is coupled to the discharge conduit. Also optionally, a removable solid waste hopper is located at the lower end of the inclined screen. Otherwise the solid waste simply falls into a compost pile at the bottom of the inclined screen.
