Abstract

An ammonia removal system can remove ammonia from liquid, and can include an ammonia removal portion having liquid flow surfaces for flowing the liquid downward with gravity, and for receiving vapor moving upwardly past and over the downward flowing liquid for absorbing and removing ammonia from the liquid. An evaporator can be positioned below the ammonia removal portion for receiving the downward flowing liquid now with reduced ammonia from the ammonia removal portion. One portion of the liquid with reduced ammonia can evaporate and produce the vapor for moving upwardly into the ammonia removal portion for removing the ammonia. Another portion of the liquid with reduced ammonia can be drained for removal or use. A compressor can be in communication with the ammonia removal portion for compressing the vapor after exiting the ammonia removal portion. A condenser can be in communication with the compressor for receiving compressed vapor from the compressor for condensing into liquid condensate. A recirculating conduit can connect the condenser to the ammonia removal portion for recirculating at least a portion of the liquid condensate to the ammonia removal portion for reprocessing and flowing again over the liquid flow surfaces.

Abstract

A distiller for processing liquid influent, including a heating chamber. An evaporation arrangement can be positioned above the heating chamber and can include spaced apart evaporation surfaces forming a bottom evaporation stage, multiple intermediate evaporation stages, and an upper evaporation stage. The bottom evaporation stage can be in thermal contact with the heating chamber, and the multiple intermediate and upper evaporation stages can be sequentially positioned above the bottom evaporation stage one above another. The bottom and intermediate evaporation stages can evaporate at least a portion of the liquid influent applied thereon forming vapor and heating the stage positioned above with the vapor. A liquid delivery system can provide the liquid influent to the upper evaporation stage for initial evaporation, and transfer at least a portion of the liquid influent in the upper evaporation stage and intermediate evaporation stages downwardly in sequence to a stage below until reaching the bottom evaporation stage for sequential evaporation at each evaporation stage. A solids transfer system can move solids on an evaporation surface of the bottom evaporation stage remaining from evaporated liquid influent to the heating chamber for combustion and providing heat.

Abstract

A distilling device having a vapor compression distiller. The vapor compression distiller can include a reservoir for receiving liquid for distillation. Evaporation surfaces can receive the liquid and evaporate the liquid into evaporated vapor for subsequent condensing. Condensing surfaces can receive the vapor and condense the vapor into distillate. A compressor can deliver the vapor to the condensing surfaces. The distilling device can also include an engine that produces heat. A boiler can be heated by the heat from the engine for producing a working vapor. A vapor turbine can be driven by the working vapor. The vapor turbine can be mechanically coupled to the compressor for mechanically driving the compressor, thereby reducing electrical power needs of the vapor compression distiller.
