Abstract: A desalination process including heating brine in a preheating chamber and transferring the brine to a rotary kiln to be sprayed against the wall structure of the rotary kiln to boil to steam and a residue of salt/impurities, the exiting steam being pressurized in a compressor and passed to an externally powered heater to be heated and then fed to a hollow wall structure of the rotating kiln in which the steam condenses to pure water to be transferred to the preheating chamber to preheat the incoming brine, the rotating kiln being arranged to rotate past a scraper to remove salt/impurities from the wall structure for collection at the base of the kiln.

Abstract: The present invention discloses a comprehensive, efficient, and cost effective portable evaporator unit, method, and system for the treatment of brine. The evaporator unit, method, and system require a pretreatment process that removes heavy metals, crude oil, and other contaminates in preparation for the evaporator unit. The pretreatment and the evaporator unit, method, and system process metals and brine at the site where they are generated (the well site). Thus, saving significant money to producers who can avoid present and future increases in transportation costs.

Abstract: A liquid evaporation method and apparatus wherein the contamination of the heat transfer surfaces is avoided by using a special circulating fluid. The liquid to be evaporated is heated in direct contact with the circulating fluid and conveyed to a vapor separation tank. In the evaporator according to the invention, heat transfer surface contamination may be limited by mixing the liquid to be evaporated with the circulating fluid only after the heat exchanger so that the heat surface contaminating liquid to be evaporated does not make direct contact with the heat surface.

Abstract: A wastewater evaporator system is provided for evaporating wastewater at a rate of about seven gallons per hour. Such system includes a heater, a blower, a plurality of honeycombed plates, a drive element including an electric motor, and a tank. Such system improves the environment and allows safe, reliable, and economical disposal of wastewater.

Abstract: The present invention includes an apparatus and system for treating waste water. More specifically, for the removal of a floating component of the waste water from the remaining water relatively free of the floating component. The apparatus includes a separating chamber having a movable flow gate disposed at one side thereof. A preferred embodiment of the present apparatus includes a skimmer that is movable in both horizontal and vertical directions for facilitating the removal of the floating component of the waste water from the separating chamber. The present system includes an apparatus for treating waste water and sludge.

Abstract: A waste solution treating apparatus used in combination with a photographic processing apparatus wherein a photographic material is automatically processed with a processing solution and dried in a drying chamber and a predetermined amount of the processing solution is run to waste and supply replenishing solution continuously comprises a housing for a treating chamber; a member for discharging the processing solution to be wasted into the treating chamber; a treating device in the housing for allowing the processing solution discharged into the treating chamber to flow thereover thereover; an air conducting member for supplying air heated in the drying chamber into the treating chamber to heat the treating device with the heated air in order to condense and solidify the processing solution while the processing solution is flowing over the treating device.

Abstract: Pasty, aqueous sludges of industrial or sewage treatment origin are dried for further use as raw material. The sludge particles are loosened by intense motion and substantially dry gases are introduced under pressure into the loosened sludge. The moisture enriched gases are removed from the sludge. The loosening and drying may be facilitated by repeatedly and sequentially increasing and decreasing the total surface area of the sludge. The intense motion is imparted to the sludge by at least one sludge stirring member and the drying gases may be introduced through the stirring member. The surface area of the sludge may be increased by plough-shaped or scraper-shaped tools. The surface area of the sludge may be decreased by rollers.
