ASSEMBLIES AND METHODS FOR MATERIAL EXTRACTION FROM RETENTION COLLECTIONS
Assemblies and methods to extract materials from a retention collection may include a vacuum source including a series of vacuum generators configured to generate a vacuum flow to create a suction between the retention collection and a material collector for extraction of the material from the retention collection and transfer to the material collector. The suction generated by the vacuum flow will be sufficient to draw-in and convey the material in liquid, semi-solid and substantially solid states from the retention collection along a collection conduit and into the material collector for disposal. The vacuum generation assembly may include a filter and sound attenuation chamber connected to the vacuum source configured to receive and filter a vacuum exhaust fluid/air flow portion of the vacuum flow and to attenuate sound generated by the vacuum source.
1 . A method to enhance conveyance of a material from a retention collection to a material collector, the method comprising:
supplying a pressurized fluid to a plurality of vacuum generators;
generating, via the plurality of vacuum generators, a vacuum flow;
supplying the vacuum flow to the material collector and from the material collector to a collection hose to create a suction applied to the material in the retention collection, thereby to extract the material from the retention collection along a flow path defined between the retention collection and the material collector, the material extracted from the retention collection comprises liquid, semi-solid, substantially solid materials and combinations thereof;
controlling generating the vacuum flow sufficient to maintain a selected vacuum pressure at a distance of at least about 200 feet; and
depositing the material extracted from the retention collection within the material collector via the vacuum flow passing through the material collector.
2 . The method of claim 1 , further comprising passing an exhaust portion of the vacuum flow into a filter and sound attenuation chamber and filtering the exhaust portion prior to releasing the exhaust to a surrounding environment.
3 . The method of claim 1 , further comprising passing the exhaust portion of the vacuum flow through a sound attenuation assembly to reduce a sound level generated by one or more of the vacuum flow or generating the vacuum flow.
4 . The method of claim 1 , wherein generating the vacuum flow comprises receiving the pressurized fluid at the plurality vacuum generators, supplying the pressurized fluid to a manifold, and distributing the pressurized fluid from the manifold to a plurality of venturi mechanisms and using a venturi effect to generate the vacuum flow.
5 . The method of claim 1 , further comprising removing water from the material extracted.
6 . A method to enhance conveyance of a material from a retention collection to a material collector, the method comprising:
supplying a pressurized fluid to a plurality of vacuum generators;
generating, via the plurality of vacuum generators, a vacuum flow;
supplying the vacuum flow to the material collector and from the material collector to a collection hose to create a suction applied to the material in the retention collection, thereby to extract the material from the retention collection along a flow path defined between the retention collection and the material collector, the material extracted from the retention collection comprises liquid, semi-solid, substantially solid materials and combinations thereof;
passing the exhaust portion of the vacuum flow through a sound attenuation assembly to reduce a sound level generated by one or more of the vacuum flow or generating the vacuum flow;
controlling generating the vacuum flow sufficient to maintain a selected vacuum pressure at a selected distance; and
depositing the material extracted from the retention collection within the material collector via the vacuum flow passing through the material collector.
7 . The method of claim 6 , wherein generating the vacuum flow comprises receiving the pressurized fluid at the plurality vacuum generators, supplying the pressurized fluid to a manifold, and distributing the pressurized fluid from the manifold to a plurality of venturi mechanisms and using a venturi effect to generate the vacuum flow.
8 . The method of claim 7 , further comprising removing water from the material extracted.
