Abstract: A volumetric flow measuring and metering device for flowable solids as a flow passage through which a flow of bulk material may be passed. An obturating device is positioned at the bottom end of the flow passage and is movable in a linear direction toward and away from the bottom end. The obturating device is positioned relative to the bottom end of the flow passage at a distance that imparts a consolidated, column-like flow of the bulk material in the flow passage. A speed sensor operates to measure a speed of consolidated, column-like flow of the bulk material in the flow passage. A controller uses the speed data from the speed sensor to calculate a volumetric flow rate of the bulk material flowing through the flow passage. The obturating device can be selectively positioned to increase or decrease the volumetric flow rate of the bulk material. Other aspects are also provided.

Abstract: A compact fluid purification device includes a housing having an inlet for receiving unfiltered liquid and an open end and a first valve disposed within the inlet and being configured to only permit unfiltered liquid to flow into a hollow interior of the housing. The device has a plunger that is movable between a fully extended position and a fully retracted position. Movement of the plunger toward the fully extended position causes unfiltered liquid to be drawn into the interior of the housing and the device includes a second valve disposed within the outlet and being configured to only permit filtered liquid to be discharged from the plunger housing. The unfiltered liquid is filtered when the plunger is moved toward the fully retracted position causing the unfiltered liquid in the interior to flow into the inside of the filter elements and then across the filter elements and into the outlet.

Abstract: A Water and Wastewater Treatment Aerated Mini-Dosing air-lift pump System and filter housing, that replaces the conventional dosing pump, controls and additional Tank. It is adaptable to all access ports and uniquely smaller than a 3? inspection port and is integrally positioned in an existing or new raw water pretreatment or pump tank. It aerates the source pool thereby mitigating: H2SO4 gases, odors and source pool BOD5. The system communicates with an above ground aerator and optional controls and in it's plurality supplies dissolved and free oxygen to the pump, housing, effluent and the source pool, with surge protection and scum mitigation. Mini-metering and, low pressure, extended cycle durations increase the average microbial production balance and microbial Ratio to nutrients BOD. The raw sewage tank no longer requires gas removal prior to inspection due to oxic and anoxic microbial processes that mitigates H2SO4 gases.
