Abstract:
A portable drinking water filter system, such as a pitcher, having a sleeve and a floatable body including a filter opening configured to receive a water filter, the floatable body having a seal extending outward from an outer surface of the floatable body. The floatable body is disposed in a sleeve cavity such that a body seal engages the sidewall and restricts water from passing between the floatable body and the sidewall. The seal is configured to create friction with the sidewall, wherein the friction created when the floatable body rises in the sleeve is different than when the floatable body lowers in the sleeve. The friction created when the floatable body rises in the sleeve is greater than when the floatable body lowers in the sleeve, allowing the floatable body to auto-retract toward a cavity base without burping.
Abstract:
Embodiments disclosed here include a containment system and methods of containment which may include a segmented buoyant rim. Certain embodiments also include an inflatable rim with at least one inflation/deflation valve in the rim segments and ballast in the rim segments. Additionally, certain embodiments include material connected to the rim segments, to enclose a void created in the rim and to hang below the buoyant rim.
Abstract:
A floating liquid intake for a liquid suction removal system, the liquid intake comprising housing defining an internal cavity. The housing has a hollow and buoyant annular body, an upper cover and a lower cover. The internal cavity is formed between the upper and lower covers. A substantially annular inlet is formed in the annular body for ingress of liquid into the cavity. The annular body has a buoyancy sufficient for the liquid intake to float in a liquid with the annular inlet submerged below the surface of the liquid in which the liquid intake is floating. A pipe extends into the cavity and the pipe includes an inlet that in use is open below the surface of the liquid within the cavity. The pipe extends outside of the cavity for connection to a liquid suction removal system.
Abstract:
A float assembly that can generate its inflowing water current for collecting water surface debris in a water body. Float assembly can be mounted to a fixed structure at the water body and includes a basket supported by a pair of floats buoyant in water. The basket includes a pump housed in a perforated housing, wherein the pump can be operated to suck water through the inlet also carrying the debris into the basket. The debris of a suitable size can be retained in the basket while the water is pumped out through an outlet. The basket can be switched from an operating state i.e., submerged in water to a stowed state outside the water upon the fixed structure.

Abstract:
The disclosed technology includes pre-filter system that can include a filter portion comprising pipes, elbows, and tees. The pipes can include apertures. The pipes, elbows, and tees can be positioned such that a first end of a first group of neighboring pipes can be fluidly connected to form a column of fluid connection and a second end of a second group of neighboring pipes can be fluidly connected to form a row of fluid connection. The apertures of at least some of the pipes can be covered with a mesh netting. The pre-filter system can include an airtight float portion. The float portion can be attached to the filter portion to provide a predetermined amount of buoyancy to the pre-filter system.
Abstract:
A surface water outlet device for allowing water removal from a sediment pond while controlling sediment removal that includes a float formed of interconnected lengths of pipe sealed against water intrusion and a drain pipe attached to the float and having a plurality of openings to allow water to drain into the drain pipe. A swivel is positioned intermediate the float and the drain pipe and adapted to allow the float to rise and fall with the water level in the sediment pond and to allow the drain pipe to pivot relative to the float as the floats rises and falls with the water level. An annular slide pipe is positioned over the drain pipe and is moveable along the length of the drain pipe to cover a varying length of the slots to correspondingly vary the rate at which water flows into the drain pipe through the slots.
Abstract:
A cold water piping system including a floating platform having horizontal and vertical surfaces, the platform including a moon pool generally in the middle of the horizontal surface in the form of a vertical cylinder with four recesses having a rectangular shape, an articulating interface suspended directly from the platform, the interface including a tubular shape made of fabric and a bellows assembly disposed at a bottom portion thereof. The system also includes at least two suspension cable assemblies secured to the platform, where the at least two suspension cables cross the moon pool, vertically mounted modular elements, where ends of the suspension cable assemblies are fastened to a top modular element at four diametrically opposed points, and a strainer having sea water intakes including a counterweight connected to the lowest modular element. The system also includes winches disposed on the horizontal surface of the platform and deployment cables connected to the strainer and winches.
Abstract:
A float device for use in drawing liquids such as fuel from a tank or other reservoir is disclosed. The device comprises a float arranged for rising and falling with the level of liquid in the tank and a liquid pick-up duct, which comprises a flexible tube having its free end coupled to the float. The float is arranged for vertical movement within a filter or other member, which encloses the float and the flexible tube. The filter or other member is elongate and tubular in construction and comprises an open lower end.
Abstract:
A storm water nutrient separating vault has a floatable filter basket therein for collecting debris entering the storm water filter vault which basket rises and falls with the water level in the vault. The floatable filter basket has a pair of swiveling trucks attached thereto. Each truck is supported on a generally vertical track mounted to a wall of the vault on one side of the vault's inlet and has a plurality of rollers riding in the track. The floatable filter basket can therefore swivel or tilt while rising or falling with the water level in the vault to maintain an opening in the nutrient collecting basket in front of the vault's inlet for capturing floating debris in the storm water entering the vault.
