  • the baffle there may be one or more openings in the baffle positioned below the midpoint of the baffle for allowing water to pass from the skimmer chamber into the other chamber (e.g. UV and/or filter chamber) in the event of debris clogging the first opening, increased flow, filter demands, etc.
  • the collection basket includes an arm extending upward that comprises an opening in registry with the baffle upper opening.
  • the second, upper opening is covered by a grate or screen.
  • the second chamber includes, but is not limited to, a filtration chamber that includes at least one filter for removing contaminants from water received in the housing that subsequently passes through the water skimmer and filter.
  • This filtration chamber is in direct water communication with the skimmer chamber.
  • the invention preferably further comprises a UV light chamber.
  • the UV light chamber has a system for eradicating microorganisms.
  • the UV light chamber is in water communication with the filtration chamber whereby water passing from the skimmer chamber into the UV light chamber will pass into the filtration chamber.
  • the filtration chamber is in water communication with the pump chamber whereby water passing from the skimmer chamber, through the UV light chamber, and through the filtration chamber will pass through the pump chamber whereby the processed water is returned to the decorative pond.
  • the object of the present invention is to skim debris from the surface of a body of water and to filter and remove smaller debris or particulate matter from the entire depth of the body of water.
  • the advantage of the present invention is to provide an effective skimmer apparatus having a partitioning baffle, comprising one or more upper and preferably one or more lower openings that separates the skimmer chamber from other chambers.

  • a skimmer chamber 124 Within unit 110 is a skimmer chamber 124, one or more filtration devices, one of which is shown at 128, a UV light chamber 126, and a pump chamber 130.
  • the pump chamber 130 draws water into the skimmer and filter unit.
  • the skimmer chamber removes the larger debris, such as leaves or other materials, from the water drawn into the skimmer filter unit, with debris collecting in basket 125.
  • the filter 128 provides for the removal of suspended or dissolved organic waste including living organisms such as algae, protozoa and bacteria.
  • the UV chamber 126 eradicates contaminants such as the algae, protozoa and bacteria.
  • the pump chamber 130 is separated from the skimmer chamber 124 by partitioning baffle 132 which also separates filters 128 that are located above pump chamber 130.
  • Baffle 132 has a miodpoint approximately halfway along its height.
  • One or more openings 136 are disposed above the midpoint of the baffle 132.
  • one or more openings 134 are disposed below the midpoint of baffle 132.
  • one of the openings is disposed below the skimmer basket shown at 134 and another opening 136 is preferably positioned higher or above the skimmer basket upper rim.
  • the partitioning baffle 132 is best seen in Fig. 5 where the ports or openings 134 and 136 are shown. Opening 134 is formed in a curved portion 138 of partitioning wall 132.
  • the curved portion 138 includes a tab 140 that descends into opening 134 but is laterally displaced so it bears against the corresponding curved portion of the UV light chamber 126. This allows water to pass through opening 134.
  • opening 136 includes a member 142 that is laterally displaced so as to bear against the outer wall of UV chamber 126.
  • the pump chamber 130 includes the pump 150.
  • the embodiment with two UV light chambers 26 and 26' the ports or openings that are above the top level of the skimmer basket 25 are shown at 50 in the arm 52 that is connected to skimmer basket 25.
  • Water flow through the skimmer filter unit will be described in reference to Fig. 2, where the flow is indicated with arrows. Water enters housing 20 through opening 17 over weir door 18, and flows into skimmer chamber 24, then through the ports, one of which is shown behind screen or grate 50 located above the upper rim of basket 25.
  • the water passing through the ports in partitioning baffle 31 flows into UV light chambers 26 and 26', which subject the water to high-intensity UV light for purification and eradication of contaminants such as single-celled algae or microorganisms.
  • UV light chambers 26 and 26' After passing through UV light chambers 26 and 26', the water flows into filtration chamber 28 for the mechanical removal of suspended solids and biological treatment for the removal of dissolved organic compounds.
  • Filtration chamber 28, supported by UV mount 40 and 40' can perform this function with one or more cartridge- based biomechanical filter mats, or other suitable filtration methods and/or devices.
  • a pump (not shown) disposed therein pumps the processed water out of unit 10 back into the pond.
  • Fig ⁇ S shows a perspective view of skimmer basket 125 of skimmer chamber 124 for use in the UV light chamber (preferably single UV chamber) embodiment of Fig. 3.
  • Skimmer basket 125 is removable by way of reaching into the interior of tank 120 and grasping handle 127 affixed to an arm 129 extending upward from the top of basket 125 so as to place handle 127 conveniently within reach after removal of the skimmer filter unit lid. In this manner, skimmer basket 125 is readily removed, cleaned, and/or replaced from tank 120 as needed.
  • the arm 129 also includes an opening or port 144 covered by a screen 150 so as to block large debris from entering the UV chamber.
  • Opening 144 when basket 125 is in position within skimmer chamber 124 directly overlies, or is in registry with, upper opening 136 in partition baffle 132 (see Fig. 3) thus allowing water to pass into the UV chamber even if the basket 125 is so clogged with debris that water cannot flow through basket 125 and thereby reach lower opening 134.
  • the arm 129 is shown having an opening 144 and a grate 150 that is formed integrally out of the arm 129 which may be a molded plastic piece including an integral handle 127.
  • the arm 129 is attached to basket 125 through fasteners or other attachment devices through openings 152.
  • the purpose of the grate or screen 150 is to serve as an auxiliary blocker of larger debris when either basket 125 or lower opening 134 of the single UV light chamber embodiment shown in Fig. 3 is restricted due to foreign debris, or in the event there is increased water flow, larger flow demand and/or filter demand.
  • the water will continue to rise in chamber 124 above the top of basket 125 and it is necessary for continued functioning of the unit that the water is allowed to pass into the UV chamber through this upper non-clogged opening. But since the debris may then bellowing on the surface of the water as it rises to the opening 144 it is still desirable to block or screen the floating debris from passing into the UV chamber from the skimmer chamber. Thus, the unit will continue to function as a skimmer as well as a filter.
  • a baffle block can be used to prevent water flow to one of the UV chambers 26 or 26'.
  • water bodies less than approximately 5000 gallons may require operation of only one UV chamber for sufficient purification.
  • Table 1 provides examples of UV lighting power and approximate gallons per hour (GPH) of water flow required through the UV light chamber for sufficient water treatment:
  • power is preferably removed from the UV light for approximately 24 hours to allow the bacteria to settle.
  • Filtering can be achieved, for example, with a biomechanical filter mat, or other suitable filtration means, secured within a housing or cartridge that is placed within the filter chamber 28 of the embodiment shown in Fig. 2.
