A tank system may be conventional and fixed, or mobile, such as a fracking fluid or other tank trailer. A drain port thereof is fitted with an adapter connecting a snorkel system to drain liquids from near the top of the liquid level in the tank. A snorkel head at the extreme distal end of a tube near the longitudinal center of the tank is suspended by a system of buoys. A flow field controller plate resists formation of vortices near the snorkel head, so it can operate as near the surface as possible, withdrawing the highest grade oil efficiently. At its exit, the proximal end of the tube drains oil through an inner conduit of an adapter at a penetration in the wall of the tank. The adapter forms an annulus around the inner conduit draining tank bottoms directly from the tank.

A compact extractable self-contained decanter that is sealed for powered suction of supernatant from a wastewater tank without clogging from filters.

Provided is a liquid processing apparatus and a liquid processing method for reducing a waste amount of a high specific gravity liquid. The liquid processing apparatus includes: a supply pump; a bubble tank including an inflow port, an overflow port, and a return port; a microbubble generator disposed outside the bubble tank; a recovery tank having a recovery port to recover the processing liquid overflown from a first liquid level to the tank; a separation tank including a settling tank connected to the overflow port, and a floating tank connected to the settling tank at a lower portion, and an ejector having a inlet port connected to the supply pump, a suction port connected the suction body, and a discharge port connected to the return port.

The present application includes a tank into which water to be treated flows, an imaging device for capturing an image of water into which coagulant has been added and that is stored in the tank, and a control device for performing grayscale processing of the image captured by the imaging device, performing differential processing of the image subjected to the grayscale processing, and determining the state of the aggregate in the water based on the feature value calculated from the result of performing differential processing.

A separator, for separating solids from a liquid, comprises a hydrodynamic separator, a first filtration device, a first backwash device, a second filtration device, and a second backwash device. The first filtration device comprises a first inlet at a first level for receiving at least a first portion of the liquid from the hydrodynamic separator, and a first filter for filtering the first portion of the liquid received via the first inlet. During filtration of the first portion of the liquid, the first portion of the liquid passes through the first filter away from the first inlet and a first portion of solids is retained by the first filter. The first filter is located between the first inlet and the first backwash device. The first backwash device is configured to alternately prevent and allow the passage of the first portion of the liquid through the first backwash device such that, when the passage of the first portion of the liquid through the first backwash device is prevented, the first portion of the liquid that has passed through the first filter passes back through the first filter toward the first inlet so as to remove the first portion of solids from the first filter. The second filtration device comprises a second inlet at a second level higher than the first level for receiving a second portion of the liquid from the hydrodynamic separator, and a second filter for filtering the second portion of the liquid received via the second inlet. During filtration of the second portion of the liquid, the second portion of the liquid passes through the second filter away from the second inlet, and a second portion of solids is retained by the second filter. The second filter is located between the second inlet and the second backwash device. The second backwash device is configured to alternately prevent and allow the passage of the second portion of the liquid through the second backwash device such that, when the passage of the second portion of the liquid through the second backwash device is prevented, the second portion of the liquid that has passed through the second filter passes back through the second filter toward the second inlet so as to remove the second portion of solids from the second filter.

A system and method for determining when a sand separator should be purged to remove solids from the sand separator. The system can include an acoustic sensor which detects the frequency of audible sound coming from the inner chamber of the vessel and generate a signature signal representative of the frequency of audible sound. There is a processor connected to the acoustic sensor and configured to compare the signature signal with a set frequency range of audible sound which in turn generates a signal indicating when the signature frequency and the set frequency are in overlapping relationship.

The system for a continuous dewatering recirculating for removing particulate such as coal combustion residue from a water stream. The system includes multiple dewatering and recirculation containers, each having a submerged flight conveyor and lamella settlings plate located therein, at least one dewatering and recirculation container receives ash water stream overflow.

An apparatus and method for optimizing hydro-cyclone separation in a filtering system is disclosed. The apparatus includes a first, second and third storage tanks, a pump, a motor, a variable speed drive, and a hydro-cyclone. The pump pulls fluid from the third storage tank and routes it to the hydro-cyclone where particles are separated out. The filtered fluid is then routed onto a mechanism, such as a car wash, where the clean fluid is utilized. Since the car wash cannot always use all of the filtered fluid, a controller monitor flow rate and fluid pressure, and operates a proportional fluid control valve to bypass some or all of the fluid routed to the car wash and redirect it back to the second storage tank. This process allows the hydro-cyclone to operate at maximum efficiency while flow to the carwash may vary. The dirty particles separated out by the hydro-cyclone are routed to the first storage tank.
