摘要:
Thickening method and apparatus includes conventional settling vessel with moving rake and pickets at the bottom thereof to promote sludge settling and compression and a plurality of inclined passageways for upwardly flowing liquid. Upflowing liquid from the hindered settling feed is clarified in the inclined passageways from which a presettled semisolid mass flows downwardly into a detention zone of compressive thickening sludge. This interrelationship of inclined passageways and compressively thickening zone enhances the effectiveness of the thickening process.
摘要:
A method of performing acoustically enhanced sedimentation in a sample of a suspension comprising particles and a fluid is provided. The method comprises the steps of: i. introducing a volume of the sample into an accumulation zone of a microfluidic cavity; ii performing the substeps of: a. during a first time period: subjecting the volume to an acoustic standing wave configured to cause the particles in the volume to accumulate in at least a first region of the volume; b. during a second time period: subjecting the volume to a gravitational field affecting the particles and the fluid so that the particles accumulated in the at least one first region sediment in a first direction in relation to the direction of the gravitational field, thereby removing particles from the volume; and iii. moving the volume in a second direction opposite the first direction by introducing a subsequent volume of the sample into the accumulation zone of the microfluidic cavity. An acoustofluidic system is also provided.
摘要:
The invention relates to a method for separating the liquid part from the suspended matter in a sludge supplied in a continuous flow at a flow rate of QEB=V/hour. The flow is divided into at least two partial flows which are sprayed on top of one another into a sealed chamber of volume v
摘要:
A cavitation reactor having a pulse valve for receiving an input fluid flow and generating a pulsed output flow that is provided to the input of a resonance chamber, such as a tube. The pulse valve uses a shaft with a number of regularly spaced lands to form fluid conduits between an input port and the output port connected to the resonance tube to cause fluid communication between the input and output ports to be regularly opened and closed, thereby producing a pulsed output that drives the formation of resonance waves in the resonance chamber. The shaft is rotated at a suitable frequency to produce cavitation bubbles that collapse in the resonance chamber without damaging the valve shaft.
