摘要:
There is disclosed a fluid distribution system for distributing fluid from a single source to a plurality of downstream receptacles. The system has a distribution manifold assembly with a single inlet and a plurality of outlets arrayed around a circumferential outer periphery. The outlets may be directed to the different receptacles which each have their own vent filter, or each receptacle connects back to the distribution manifold for common venting. The distribution manifold assembly may be formed by identical fluid and vent manifolds with cylindrical exteriors, or by identical fluid and vent manifolds surrounded by cylindrical frame members, to form a compact cylindrical combined assembly. Flexible conduits connect the manifold assembly to a plurality of receptacles, and a consumable subsystem of the manifold assembly, conduits and receptacle caps may be pre-assembled for ease of use.

摘要:
The present invention relates to the raw water-filtering technical field, and is to provide a high speed filtering apparatus which can filter a great amount of raw water containing suspended substances (SS) at a high concentration at a high speed. Floating filter media 2, which are composed of a foamed polymer having an apparent density of 0.1 to 0.4 g/cm3 and a 50% compression hardness of not less than 0.1 MPa and have uneven shapes or cylindrical shapes with sizes of 4 to 10 mm, are charged into an up-flow type filtering tower 1. The raw water containing SS at a high concentration is filtered by passing it through the filtering tower 1 at a linear water-passing speed of 100 to 1000 m/day. While the floating filter media 2 are not compacted, a high SS-capturing percentage can be obtained. Back washing can be also effected at a high linear washing speed of 1.2 to 4.0 m/min.

摘要:
The invention is directed to an automatic backwash filter system that includes at least one influent port for introducing a fluid to the filter; a plurality of partitions forming a plurality of compartments for holding a filtering media for filtering the fluid; at least one porous plate for supporting the plurality of partitions; wherein each of the partitions is mounted atop a continuous portion of the porous plate; and at least one effluent port for draining the fluid away from the compartments. The filter may also include a filter media comprising one or more selected from the group consisting of sand, anthracite coal, and activated carbon. The invention also includes a method for preparing the automatic backwash filtering system that includes the steps of arranging a plurality of partitions to form a plurality of compartments for holding a filtering media for filtering a fluid; binding together a plurality of porous plates by a lap joint at least one of the partitions; and securing the plurality of partitions to the plurality of porous plates so that each of the partitions is mounted atop a continuous portion of the porous plate to prevent the filtering media from passing therethough. Each of the plurality of partitions may be secured to the porous plate with angles and mounting bolts.
摘要:

摘要:
Automatic backwash filter systems including a filter tank divided by vertical cell sheets into a multiplicity seriate cells are improved by provision, as retention for underdrain filter plates within the seriate cells, of unique contoured cell sheets having profiled faces each with a lower level, integral, protrusion segment that forms a support ledge for a cell filter plate and a higher level, integral, protrusion segment that provides a filter plate holddown feature in combination with filler members and horizontal retention bars.
摘要:
A liquid filtration system is provided which includes a traveling bridge device mounting air scour and backwash means for successively cleaning each of a plurality of filter cells formed in a filtration tank. The air scour means includes a first hood open to atmosphere and adapted for sealing engagement with each filter cell. The first hood may include an air scour inlet conduit for supplying air under pressure to each cell. The backwash means includes a second hood also adapted for sealing engagement with each filter cell and includes a backwash conduit for creating suction within each filter cell. In one embodiment where the air scour pump is mounted on the traveling bridge carriage, each cell is provided with a vertical riser adapted for sealing engagement with the air scour inlet conduit in the air scour hood. In an alternative arrangement, the air is supplied from a ground installed pump, through a common inlet manifold, to the individual cells. In this embodiment, the air flow is regulated by valves located externally of each cell, and successively actuated by a control arm mounted on the carriage.
摘要:
In a modular water filtration and companion backwash assemblage, a reservoir is sectioned into an upper, supply chamber and a lower, drain chamber by a plurality of modular, horizontally co-planar filter cells. A carriage assembly is selectively positioned over an individual cell and a depending backwash hood is lowered to isolate, hydraulically, the modular cell. Water is pumped upwardly, out of the hood, expanding and scrubbing the filter media. Jetwash probes intensify the cleansing action, and a baffle plate having displacement accelerators ensures equal but swift upward displacement of backwash waters. Each cell is sequentially backwashed on a continuous basis, allowing uninterrupted operation of the other filtration modules.
