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 development is a septic tank or wastewater treatment tank outlet filter cleaning device. More specifically, the device is an outlet filter cleaner for a slotted filter used to reduce solid waste transfer into a septic tank effluent. The device comprises a central shaft with at least one cleaning disc, wherein the cleaning disc comprises a body which is mounted on the shaft and wherein a plurality of fingers protrude from the body, preferably in locations substantially identical to the positions of the openings in the wall of the tube.

A sedimentation device for separating a solid-liquid suspension has a settling tank, a feed well, a feed pipe, an overflow collector and a mixing area. A pump is disposed in the overflow collector and overflow from the overflow collector can be fed through the pump to the mixing area. The solid-liquid suspension to be clarified can be diluted without affecting the sedimentation process, the chemicals can be used to the optimum, and the amount of overflow fed to the mixing area can be exactly determined.

A screw type separation device includes: a casing that has a separated liquid discharge port on one end part side and has an object discharge port on the other end part side, while the other end part side is positioned lower, in terms of vertical directions, than the one end part side; a screw shaft provided inside the casing; a first screw blade; and a second screw blade that forms a first space between one face and the first screw blade facing the one face and forms a second space between the other face and the first screw blade facing the other face.

A seawater distillation system for distilling seawater and brine and removing salt. The seawater distillation system includes an apparatus having at least a vessel, a separation assembly, and at least one mist eliminator. The vessel may be adapted to hold a volume of seawater comprising a volume of salt, wherein vessel is one of externally heated and internally heated to evaporate the volume of seawater to a volume of steam and to precipitate the volume of salt. The separation assembly may be operably engaged with the vessel, wherein the separation assembly is configured to separate the volume of salt from the volume of seawater inside of the vessel. The at least one mist eliminator may be operably engaged with the vessel and positioned vertically above the separation assembly, wherein the at least one mist eliminator is configured to eliminate water droplets and salt from the volume of steam.

An improved clarifier tank having a rake arm assembly with one or more rake arms, a rake arm driveshaft operatively connected to the rake arms and a rake arm drive, and a sump scraper driveshaft, operatively connected to a plurality of sump scrapers and a sump scraper drive.

A vertical dryer system and method for managing oil well solids and liquids includes a vertical dryer; a hopper for well drilling cuttings mixed with residual liquids; and an enclosed drag chain conveyor having an opening into the hopper for picking up drill cuttings and associated liquids. The enclosed drag chain conveyor extends from the hopper to a vertical dryer, there being an opening in said enclosed drag chain located at said vertical dryer, whereby drilling cuttings and associated fluids being conveyed by said drag chain are delivered to said vertical dryer for drying. The enclosed drag chain conveyor returns again to said hopper in a continuous enclosed loop except for the openings.

A method of concentrating sediment in a water tank involves attaching a vortex inducing device to an opening through the roof of the tank between the central vertical axis and the side walling of the tank. The device has a device inlet which narrows to a device outlet. The device outlet is orientated such that, water flowing out via the device outlet induces a vortex within the pooled water, thereby causing sediment to collect centrally on the floor of the tank.

A skimming apparatus with a pivot arm and a drive follower on the pivot arm that guides a belting to facilitate precise placement of the belting for efficient skimming.

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.
