US Patent 7309443 Skimmer and filter

The present invention provides a skimmer and filter unit for use with a body of water. The unit comprises a housing, a basket for collecting debris, and a partitioning baffle with upper openings and optionally lower openings, and a microorganism eradication system within the housing. The baffle's lower opening is preferably positioned below the rim of the perforated basket and its upper, screened or gated opening is positioned above the rim of the basket for allowing water to pass in the event of debris clogging the first opening, overflow conditions, larger flow demand, and/or filter demand.
