A scrubber for treating exhaust gas generated by combustion of biomass comprises a plurality of chambers each configured to apply a scrubbing medium to the exhaust gas for removing solid particles from the exhaust gas. A first chamber includes at least one nozzle configured to dispense scrubbing liquid in a sheet oriented transversely to a path of flow of exhaust through the first chamber. A second chamber defines a reservoir for containing a bath of scrubbing liquid and further includes a baffle configured to deflect the exhaust gas into the bath. A third chamber is arranged to support a sheet of solid filter medium spanning across the chamber.

Systems and methods for intensive recirculating aquaculture are provided herein. An example system includes water sourced from a first segment of a saline aquifer, a recirculating aquaculture system receiving the sourced water and producing discharge water, and a water discharge point located within a second segment of the saline aquifer disposed below the first segment of the saline aquifer.

A system for transferring marine life within an aquaculture facility including a plurality of segregated storage facilities each containing water for marine life, maintained within a predetermined temperature range and supported at independent ground levels. The storage facilities are successively disposed and structured to contain marine life at different stages of growth. A transfer assembly includes a path of fluid flow interconnecting successive ones of said plurality of storage facilities in fluid communication with one another, wherein at least a majority of a length of said path of fluid flow is disposed beneath the independent ground levels at a predetermined depth, which is sufficient to facilitate maintenance of the path of fluid flow within the predetermined temperature range, via geothermal cooling.

The transfer assembly may also connect a holding facility, which may be dimensioned and structured to transfer mature marine life, possibly on an on-demand basis, to the harvesting facility.

A separation apparatus for separating constituents from effluent. The separation apparatus includes a gas diffuser, a hopper, and a tank. The gas diffuser includes an inlet inner tube for receiving effluent from a well. The hopper is disposed at least partially below the gas diffuser, and the tank is connected to the hopper. The gas diffuser is configured so that gas in the effluent is released from the effluent and into the atmosphere before the effluent enters the hopper. The hopper is configured so that liquid effluent in the hopper spills over a top portion of the hopper and into the tank.

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.

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.

A remote submerged chain conveyor system separates particles from a coal ash/water slurry from remotely located boiler units. A tank forms an ash holding section, a dewatering section, and an ash settling section. The ash holding section receives the slurry with first and second opposite ends. The dewatering section dewaters the slurry. The settling zone is an elongated trough connected with the ash holding section at one end with a discharge drain trough at near an opposite end. The tank sections are in a generally linear arrangement. A drag chain moves along the ash settling conveying the particles settling from the slurry to the dewatering section opposite to a net flow of water. A flocculant supply line upstream of the ash settling section configured for adding a flocculant promoting an agglomeration of particles into flocs. The flocculant supply line is located in a mixing section with an agitator.

An apparatus for reducing the water content of waste water sludge includes a column for receiving waste water sludge, an outlet at a lower end of the column, a first closure for closing the outlet of the column, a controller for controlling the opening and closing of the closure. The controller is adapted to open and close the first closure to periodically discharge amounts of settled fines from the lower end of the column. A water outlet is adapted to receive water overflowing from an upper end of the column.
