Abstract:
A liquid filtering system and methods for filtering are disclosed. One embodiment of the system includes a filtering apparatus having a receiving receptacle coupled with an adapter. The adapter has an adapter port for receiving a vacuum and an interface for coupling with an output receptacle that receives filtered liquid from the filtering apparatus. The adapter is between the receiving receptacle and output receptacle when the output receptacle is coupled with the adapter interface. The system also includes a base having a substantially rigid housing containing an internal vacuum channel terminating at a base vacuum delivery port. The adapter is couplable with the base to connect the adapter port to the base vacuum delivery port.
Abstract:
The present invention provides a vacuum filter device (10) which includes a filter body (11) having two holders (12, 13) on opposite sides of a filter. Each holder contains a closed container (15, 16) in a fluid-tight, sealed relationship. The filter is retained by a compression sealing element that resiliently applies a sealing pressure to the upper surface of the filter. The sealing element is maintained in place by a compression element formed of a ring that applies a desired compressive force to the sealing element. The compression element is bonded to a portion of the body to hold it, the sealing element and filter in place and under a compression seal. Other aspects of the invention include provisions for forming a port in the compression element that can be aligned with the vent of the device. The invention also can provide for an alignment feature on the compression element that ensures the port is in alignment with the vent of the device. The device also includes a vacuum port (26) communicating with the downstream side of the filter, and hence the filtrate container.
Abstract:
A liquid extraction unit for extracting liquid from an aqueous material is described. The unit includes a filter that is configured to allow passage of the liquid and prevent passage of the aqueous material. The unit also includes a first vacuum that is configured to extract air from the extraction unit. The unit further includes a second vacuum that is configured to pull the liquid through the filter. The first vacuum and the second vacuum are located after the filter.
Abstract:
Method and apparatus for separation of solid particles in liquid suspension by non-continuous filter unclogging aided filtration. The said method uses vacuum as suspension flowing force, which is applied under a closed circuit. The said separation is based on filtration vessels, using filtration fabrics of known mesh, and uses a reverse direction of suspension flow and air suction through the filters to avoid clogging of the filter fabrics. The separated particles can be recovered and collected from any of the filters for subsequent use or simply discarded. In a particular form of the invention, the said apparatus is used to separate fungus spores from solid medium in suspension. The said apparatus is constituted by a support structure and comprises three interconnected systems: the filtration system, the vacuum system and the control system. The said filtration system comprises column reservoirs (2, 4, 24, 22), suspension transport tubes (25) and filters (3 and 23). The said vacuum system comprises a vacuum pump (5), air suction tubes (6) and a liquid trap (9). The said control system comprises a vacuum controller (28), suspension flow control hydraulic valves (14,19, 20, 21), air entrance control hydraulic valves (13, 11, 18, 17) and vacuum control hydraulic valves (7, 8, 12, 10, 15, 16).
Abstract:
A device for purifying liquid in a reservoir and including a vacuum chamber (1) having an inflow opening (2) and an outflow opening (3) adapted to communicate with the liquid in the reservoir through a feed conduit (4) and a return conduit (5), respectively. The return conduit (5) is provided with a pump (6) and the vacuum chamber is connected with a vacuum pump (7). The device further includes a filter cartridge (8) provided with a plurality of filter elements, each having a flow side communicating with a central passage (26) and a flow side opening into the periphery of the filter cartridge (8). The filter cartridge (8) is arranged inside the vacuum chamber, the central passage (26) of the filter cartridge communicating with the inflow opening (2) of the vacuum chamber.
Abstract:
A manifold and filter assembly for use with a waste collection unit is provided. The manifold and filter assembly directs and filters medical waste flowing into the waste collection unit. The manifold and filter assembly comprises a manifold body defining a chamber and an outlet for directing the medical waste into the waste collection unit. A manifold cap is fitted to the manifold body to close the chamber. The manifold cap defines a plurality of inlets for receiving the medical waste. A filter basket having a bottom and a peripheral wall defining a plurality of openings is snap-locked to the manifold body. The filter basket is positioned such that a fluid bypass is formed between the filter basket and the manifold body and between the filter basket and the manifold cap. The fluid bypass is in fluid communication with the outlet whereby the medical waste can flow over the peripheral wall to the outlet through the fluid bypass.
Abstract:
Liquid filter assemblies including an upper sample reservoir, a sample filter and a lower storage bottle are supported by a vacuum base. The base has a vacuum inlet port and, for connection to the liquid filter assembly, a vacuum outlet port. A vacuum is provided through the base to below the sample filter to draw sample liquid through the sample filter into the storage bottle. The base may include an auxiliary vacuum outlet port for connection with additional devices. The bases may be connected from one to another through auxiliary vacuum outlets and the vacuum inlets to make a chain of liquid filter assemblies supplied from one vacuum source. Alternatively, one base may include multiple vacuum outlet ports so that it may support and supply vacuum to a plurality of liquid filter assemblies.

Abstract:
A system for dewatering a stream of slurry has a first and a second separator. The first separator removes objects above a first size, to produce a stream of primary treated slurry. The second separator removes objects above a second size from the primary treated stream, the second size being smaller than the first size. Optionally, a third separator removes objects above a yet smaller third size from the stream of secondary treated slurry. The first separator has a plurality of sieve mat supports alternately connected to a main support frame section and a movable support frame section so that the flexible sieve mat can be agitated by the movable support frame section, a collector being provided for collecting the primary treated slurry passing through the flexible sieve mat. In an optional step, water contained in the separated solids is removed.
