Compact wastewater concentrator using waste heat

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.

Apparatus for concentrating wastewater and for creating brines

A liquid concentrator system includes a concentrator section having a gas inlet, a gas outlet, and a mixing corridor disposed between the gas inlet and the 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 remove liquid from gas flowing through the demister, and a reservoir that collects the removed liquid. A re-circulating circuit is disposed between reservoir and the mixing corridor to transport liquid within the reservoir to the mixing corridor, and a secondary re-circulating circuit includes a settling tank to separate saturated liquid and suspended solids. A custom brine mixing device is operatively coupled to the settling tank.

Apparatus for maximizing effluent liquid evaporation

The present invention generally relates to a system for treating effluent water. More particularly, it provides a robust apparatus for treating waste liquid by optimizing solar and wind energy to maximize the evaporation rate as compare to natural evaporation rate. The main object of the present invention is to provide a system for evaporating RO reject and other effluent liquid and other liquids, by optimizing system to solar and wind energy to maximize vaporization rate and recovery rate at marginal operational cost.

Liquid de-entrainment in heat exchange equipment

A kettle reboiler includes a shell, a liquid reservoir defined within the shell to contain a first process fluid, and a tube bundle positioned within the liquid reservoir and at least partially submergible in the first process fluid, the tube bundle being configured to circulate a second process fluid that causes the first process fluid to boil and discharge a vapor-liquid mixture. A liquid-vapor separation assembly is positioned in the shell and includes a separation deck, and a plurality of separation devices mounted to the separation deck, each separation device being operable to de-entrain liquid from the vapor-liquid mixture and discharge a vapor. A vapor outlet nozzle is coupled to the shell to receive the vapor discharged from the plurality of separation devices.
