The new design has three primary features: (1) a rectangular collar having a centrally located circular cutout with sewn loops formed on the outer edges of the collar; (2) a filter bag having top edges attached to the rectangular collar along the periphery of the circular cutout so that the bag is inserted within the cutout and drops below the level of the collar; and (3) a heavy gauge steel wire inserted within the sewn loops of the rectangular collar forming a structural frame along the periphery of the rectangular collar. The structural frame is preferably formed with overlapping portions coupled together with a retaining means. The overlapping portions are slidably moved relative to one another to change the first and / or second dimension of the frame so that the filter can fit within catch basins openings of various measurements.

The invention relates to bio water purifier which improves the structure of water molecular and changes the water to weak alkali drinker. The invention comprises a sediment filter removing rust and floating matters in the water, a precarbon filter removing chlorine and impurities in the water, a ceramic material tube improving the water molecule, maximizing movement of the water molecule and making weak alkali water by radiating far infrared ray, a silver carbon filter removing odor and bacteria in the water and activating the water, and a ceramic filter removing various harmful matters in the water.

The present invention relates to a high-concentration oxygen-dissolving apparatus using ultrasonic waves. More particularly, the present invention relates to a high-concentration oxygen-dissolving apparatus using ultrasonic waves in which, when liquid is introduced via an inlet port, a sediment filter filters out foreign substances, a pre-carbon filter filters out harmful chemical substances, a UF membrane filter filters out impurities, a post-carbon filter filters out gas components and odorous components, the filtered liquid is stored in a storage tank, the liquid stored in the storage tank passes through a cooling device to be cooled to a low temperature, the liquid compressed to high pressure by means of a high pressure pump and a Venturi tube is introduced into an ultrasonic wave irradiating unit,; oxygen is dissolved into the liquid by ultrasonic waves irradiated from the ultrasonic wave irradiating unit, the liquid flows to the storage tank through a flow pipe, and the liquid having an oxygen concentration higher than a predetermined level is discharged through an outlet pipe.

A storm drain sediment filter that can be adapted to cover a catch basin and be held in place by a perforated grate. In one embodiment, the filter includes a frame including four L-shaped rigid members, each of which is provided with at least two spaced apart retaining members. The four L-shaped rigid members are arranged such that a rectangular frame is formed having a total of four overlapping sections. The retaining members engage one of the overlapping portions of the frame but slidably receives the other. No retaining ends are formed at the distal end of the slidably engaged L-shaped members to serve as a sliding boundary. Instead, the dimensions of the filter bag are such that the filter bag serves to define the maximum dimension of the frame and thereby maintain the overlapping L-shaped rigid members in slidable engagement with each other. A circular embodiment is also disclosed.

A welded wire mesh is rolled into an elongated tubular wire frame, and sizing rings surround the tubular wire frame to maintain the tubular frame with a predetermined diameter. The wire frame is partially covered with a sediment filter fabric attached by wire clips, and an end portion of the tubular frame is inserted into an inlet portion of an installed storm water pipe. A collar member includes a wire collar frame secured to the tubular wire frame and is covered by a flexible filter material to filter storm water flowing between the tubular frame and the water pipe and to form a stop which prevents the tubular frame from moving further into the pipe. A top portion of the tubular wire frame is uncovered by filter fabric to define an overflow opening for storm water with very light sediment to flow into the storm water pipe.

The invention discloses a three-stage circulation aerobic reactor, which comprises a pond body, wherein the inside of the pond body is partitioned into a conical sewage expansion area, an aerobic reaction area, an anaerobic reaction area and a sediment filtering layer from bottom to top in sequence; the upper part of the aerobic reaction area is provided with a primary gas-solid-liquid separation area; the upper part of the anaerobic reaction area is provided with a secondary gas-solid-liquid separation area; three-phase separators are respectively arranged in the primary gas-solid-liquid separation area and the secondary gas-solid-liquid separation area; a water outlet weir is arranged above the sediment filtering layer; a water outlet pipe is arranged on the water outlet weir; the top of the pond body is provided with a double-stage circular reflowing system; the double-stage circular reflowing system comprises an air-lift pipe, a gas-liquid separating tank and a lower layer reflowing pipe; an upper layer reflowing pipe is arranged between the secondary gas-liquid separation area and the sediment filtering layer; and the upper layer reflowing pipe is connected with an aeration air inlet pipe arranged above the pond body. The reactor is provided with a three-stage circular reflowing system, and has the characteristics of rapid start of flocculent sludge, high impact load resistance, low requirement on the PH value of inflow water, high particle sludge increasing speed, low energy consumption, high treating efficiency and stable water yielding quality.
