Abstract:
A device for dewatering sludge comprises a plurality of screening means (11) that are located at different levels, said screening means comprising hole-provided tube pieces which communicate with a common manifold (12) and through which water may pass in a direction from the outside and inwards, without the solid constituents of the sludge being carried along by the water. When necessary, the screening means may be back-flushed in order to keep them clean, shut-off valves (24) acting between the differently high situated screening means with the purpose of individually interrupting the communication between the manifold (12) and the screening means (11) that land(s) up above the surface (9) of the slurry (8), according as its level sinks during a dewatering operation.
Abstract:
A mechanism for detecting obstacles and mechanically reversing (a direction of) a pool cleaner includes a drive part in non-rotatable connection with a cleaner housing, an arresting assembly connected to the cleaner housing, and a rotary direction-changing assembly rotatably connected to the cleaner housing or the drive part. The arresting assembly cooperates with the rotary direction-changing assembly. The mechanism for detecting obstacles and mechanically reversing (a direction of) a pool cleaner is compact in structure, low in manufacturing cost, and can perform obstacle detection and change a direction of the pool cleaner. With the structure of the rotary direction-changing assembly capable of rotating relative to the cleaner housing, the cleaner, when meeting an obstacle, is allowed to change the traveling direction, thereby resulting in a high working efficiency.
Abstract:
A filter-anchor for placement on a sea floor is provided. It includes a filter housing for filtering sea water prior to entry into a water desalinization system. The filter housing has an exterior, an interior chamber, at least one inlet for providing the sea water to the interior chamber, and at least one outlet for enabling filtered water to be pumped from the interior chamber. A sand filter is disposed in the filter housing. The filter housing has at least one water conduction outlet conduit for filtered water to be pumped to the desalinization system. A wave energy conversion system utilizing the filter anchor is also provided to effect the pumping of the filtered water to the desalinization system. A method of anchoring a wave energy conversion system and providing filtered water to a desalinization system is also provided.

Mounted on this portable device body are a motor, a pump, an input valve, an output valve, and a filtration device. Additionally, the portable device body is enabled to be carried by a user.
Abstract:
A selectively removable sludge filtration system that provides for retrofit into a container and separation of the sludge solids from the sludge liquids therein. A pair of spaced vertically oriented filter assemblies each define a filtrate cavity therein and are connected by separator plates. The filter assemblies permit the flow of sludge liquids into the filtrate cavity, but not sludge solids. A set of fasteners hold the filter assemblies in the container and bias the filter assemblies against the container bottom. The fasteners may be released to provide for removal of the sludge filtration system from the container. A fluid communication passageway directs filtrate from the filtrate cavity to a position exterior of the container. Functionally applying this sludge filtration system provides a method of retrofitting a container with a sludge filtration system and removing filtrate from a sludge in the container.
Abstract:
A vibratory apparatus for separating a liquid from a liquid-laden solid material includes a trough having a base, a deck attached to the trough, and a vibratory drive attached to the trough. The deck includes a plurality of support members extending longitudinally along the trough, each support member having a solid wall surface with an upwardly oriented apex defining a support point and two edges disposed on opposite sides of the upwardly oriented apex, the apexes being spaced from one another by a distance sufficient to support the solid material above the base, the edges of adjacent support members being spaced to define a passage therebetween, and the apexes being located at an elevation sufficiently above the base to allow liquid to drain from the solid material and flow through the passage to the base.
Abstract:
A method of separating a liquid from a liquid-laden solid material includes providing a trough having a deck defining a support surface with passages extending through the support surface. The liquid-laden solid material is deposited onto the support surface so that the liquid-laden solid material is supported by the support surface. A vibratory force is applied to the deck to separate a substantial portion of the liquid from the liquid-laden solid material. The liquid separated from the liquid-laden solid material is directed under gravity force through the passages extending through the support surface. The solid material is conveyed along the support surface by the vibratory force to a solids discharge point.
