Abstract: A localized wastewater treatment system for biologically treating wastewater. Raw wastewater flows into a first operational area where a majority of solid material in the wastewater separates out of the wastewater and is retained in a solids area positioned below the first operational area. As the wastewater continues to flow into the first operational area, the wastewater overflows from the first operational area to a second operational area. Once the wastewater in the second operational area reaches a predetermined volume, a batch of the wastewater is transferred from the second operational area to a third operational area where the batch of wastewater is biologically treated by a population of microorganisms contained within a solids area located beneath the third operational area. The treated wastewater is then removed from the third operational area for dispersal.

Abstract: A device and method for separating heavier and lighter fractions of a fluid sample. The device includes a plurality of constituents comprising a container and a composite element in the container. The composite element is a separator comprising a deformable bellows, a ballast mounted to the lower end of the bellows, and a float is engageable with an upper end of the bellows. A fluid sample is delivered to the container and the device is subjected to centrifugation whereby the centrifugal load causes the ballast to move toward the bottom of the tube and causes an elongation and narrowing of the bellows. The separator then moves down the tube and stabilizes in a position between the separated phases of the fluid sample. Termination of the centrifugal load enables the bellows to return to its original condition in sealing engagement with the walls of the tube.

Abstract: A filter assembly that filters water, particularly stormwater, that includes flow regulating, siphon inducing, and surface cleaning features that allow the filter assembly to operate at the design filtration rate for an extended period of time. During filtration, water flows inward through an annular filter medium into a drain manifold. The rate of flow into the drain manifold is controlled by a float valve assembly. A check valve permits air to escape, but not enter, the filter assembly creating a siphon effect when the rate of flow into the drain manifold is increased. The siphon effect draws water through the entire filtration surface and the entire volume of the filter medium. When the external water level decreases to the level of an array of voids in the filter assembly enclosure, the siphon is interrupted by turbulent air streams entering the filter assembly, agitating the filter surface and dislodging particulate matter.

A floating check valve is connected to each of the drain pipes to regulate the flow of water through the drain pipe. The floating check valve includes a valve element that has a density which causes the valve element to float in water and sink in oil.

Abstract: The apparatus treats storm water and includes a cylindrical basket that has a housing with a circumferentially extending air slot near the base of the housing. The basket contains an annular bed of absorbent material surrounded by a filter cartridge. Water flows radially inward through the filter and the bed into a cylindrical inner drainage space which has an outlet at its lower end, covered by a float valve. The drainage space is also in fluid communication with a one-way valve that allows air to pass from the housing into the environment. During operation, the float valve lifts when the water level rises and air is expelled from the drainage space through the one-way valve. As a result, water is continuously siphoned through the basket apparatus. When the water level drops, air enters through the air inlet slot of the housing and rises in turbulent fashion along the filter, scouring the filter and dislodging particulates.

Abstract: The present invention relates to a system which makes it possible to remove undesirable liquids, generally an aqueous phase, which precipitate to the bottom of tanks for storing liquid products. Use is made of a drainage device (30) which comprises a concave body (31), a seat (26), and an interface float (8) which has a plug portion (25). This interface float (8) is designed to sink into the product and to float on the aqueous phase. As the level of the aqueous phase drops, the plug portion (25) settles sealingly on the seat (26), halting the drainage operation since all the accumulated aqueous phase has already been drained off. The drainage system may be automatic or manual. In the former case, use is made of a sensor (12) for detecting the presence of an aqueous phase and commanding the process of opening a shut-off valve (11) and allowing drainage of the accumulated aqueous phase.

Abstract: A multi-phase separating apparatus for fluid containing a gaseous component. The apparatus includes a first tank which receives a stream of the multi-phase fluid which is to be resolved into discrete components.
