A method for water purification utilizing a cylindrical vessel containing a hydrocyclone nest. The heated contaminated water is fed into the nest, which includes a first set of hydrocyclones, at least one intermediate set of hydrocyclones, and a final set of hydrocyclones, the hydrocyclones in each set arranged in parallel, and each set arranged in series. The heated contaminated water is pumped into the cylindrical vessel such that the heated contaminated water enters a tangential inlet of each of the hydrocyclones, the hydrocyclones separate the heated contaminated water into steam and solids/concentrate, the steam exits through an overflow of the hydrocyclones and a first outlet of the cylindrical vessel, the solids/concentrate exit through an underflow of the hydrocyclones and into the subsequent ser of hydrocyclones until the final set of hydrocyclones, and then out through a second outlet of the cylindrical vessel. The steam is condensed into purified water.

A method and an apparatus for isolating potentially harmful medical substances, such as antibiotics, is disclosed. An aqueous composition, such as blackwater, contains potentially harmful medical substances present in dissolved state in bodily waste. The aqueous composition is temporarily stored in a buffer tank and is then transferred in batches to a vaporization unit comprising one or more vaporization chambers for producing a water-reduced waste material containing said potentially harmful medical substances. The waste material is subjected to a destructive treatment, such as a high-temperature incineration process.

A liquid concentrator system includes a concentrator or section having a gas inlet, a gas outlet and a mixing corridor disposed between the gas inlet and gas outlet. A liquid inlet is disposed in the mixing corridor between the gas inlet and a narrowed portion. A demister is disposed downstream of the concentrator section. The demister includes a liquid collector to removed liquid from gas flowing through the demister, and a reservoir that collects the removed liquid. A recirculating circuit is disposed between the reservoir and the mixing corridor to transport liquid within the reservoir to the mixing corridor and secondary re-circulating circuit includes a settling tank to separated saturated liquid and suspended solids. A custom brine mixing device is operatively coupled to the settling tank.

A compact and portable liquid concentrator includes a gas inlet, a gas exit and a flow corridor connecting the gas inlet and the gas exit, wherein the flow corridor includes a narrowed portion that accelerates the gas through the flow corridor. A liquid inlet injects liquid into the gas stream at a point prior to the narrowed portion so that the gas-liquid mixture is thoroughly mixed within the flow corridor, causing a portion of the liquid to be evaporated. A demister or fluid scrubber downstream of the narrowed portion removes entrained liquid droplets from the gas stream and re-circulates the removed liquid to the liquid inlet through a re-circulating circuit. Fresh liquid to be concentrated is also introduced into the re-circulating circuit at a rate sufficient to offset the amount of liquid evaporated in the flow corridor.

The invention is a high-salt waste water air powered low temperature evaporating device and method of use. A tray is mounted on a lifting platform; an air inlet and a water inlet are on the tray. Air distributing pipes are arranged at the center of the nested column tubes (33). A groove (4) is installed at the top of the tray, and mounting points are accompanied by multiple nested column tubes (33). The nested column tubes (33) are connected with the air inlet. An atomizer is arranged inside the air distributing pipes; and the atomizer is connected with the water distributing pipes. Using air power evaporates concentrated waste water multiple times so that the salt in the wastewater reaches saturated concentration, and therefore, the wastewater temperature is reduced, salt is crystallized and separated out, liquid is continuously evaporated, and the wastewater can be completely treated.

A wastewater evaporative separation system can include an evaporation panel assembly and a wastewater delivery system. The evaporative panel assembly can include at least 10 individual evaporation panels laterally joined together and fluidly coupled to a body of wastewater. The evaporation panel assembly can be configured for receiving wastewater from the body of wastewater and evaporating water therefrom as the wastewater cascades down the evaporation panel assembly and contaminants generally become more concentrated. The wastewater delivery system can be associated with the body of wastewater and can include a fluid directing assembly delivering wastewater from the body of wastewater to an upper portion of the evaporation panel assembly.

The present disclosure evaporation panel systems including a plurality of evaporation panels. The evaporation panels can include a plurality of evaporation shelves that are laterally elongated, vertically stacked, spaced apart from one another, and horizontally oriented; and a plurality of vertical support columns positioned laterally along the plurality of evaporation shelves to provide support and separation to the plurality of evaporation shelves.

The first evaporation panel and the second evaporation panel can be orthogonally connectable via the male connectors of the first evaporation panel and the female-receiving openings of the second evaporation panel.

A method for preventing fouling of a demister is disclosed. A process fluid is provided into a vessel. A gas is provided to a gas inlet of the vessel. The gas comprises a component that desublimates, crystallizes, solidifies, reacts, or a combination thereof, in the process fluid, forming a first solid. The gas is passed through the process fluid, the component of the gas forming the first solid, resulting in a component-depleted gas. The component-depleted gas is passed out of the process fluid, causing splashing or spurting of the process fluid and the first solid. The diverter section is provided between the demister and the gas inlet, the diverter section comprising a physical obstruction preventing the process fluid and the first solid from splashing or spurting onto the demister. In this manner, fouling of the demister is prevented.
