Embodiment Construction

[0038] Turning now to the attached picture, figure 1 An exemplary wastewater treatment system 10 is shown for treating power plant wastewater at a thermal power plant 12 . System 10 includes a wastewater concentrator 14 . The wastewater concentrator 14 is operatively connected at a first inlet 17 to a wastewater stream produced by one or more processes within the thermal power plant 12 , such as through a conduit 16 . The waste water concentrator 14 is also operatively connected to the hot feed gas stream at a second inlet 19 , such as through a conduit 18 . Wastewater concentrator 14 comprises a direct contact adiabatic concentration system in which wastewater concentrator 14 directly mixes the hot feed gas stream from conduit 18 with the wastewater stream from conduit 16 and evaporates water from the wastewater to form water vapor and concentrate the wastewater. Wastewater concentrator 14 separates water vapor from the remaining concentrated wastewater from the feed wastew...

Abstract

Methods, systems, and / or apparatuses for treating wastewater produced at a thermoelectric power plant, other industrial plants, and / or other industrial sources are disclosed. The wastewater is directed through a wastewater concentrator including a direct contact adiabatic concentration system. A stream of hot feed gases is directed through the wastewater concentrator. The wastewater concentrator mixes the hot feed gases directly with the wastewater and evaporates water vapor from the wastewater. The wastewater concentrator separates the water vapor from remaining concentrated wastewater. A contained air-water interface liquid evaporator may be arranged to pre-process the wastewater before being treated by the wastewater concentrator.

Description

technical field [0001] The present invention generally relates to methods, systems and / or apparatus for treating wastewater generated in thermal power plants, other industrial plants and / or other industrial sources. Background technique [0002] Thermal and nuclear power plants, including hydrocarbon fired power plants such as coal, oil and / or natural gas fired power plants, and other heavy industrial processes use large quantities of water for various processes and to provide auxiliary functions. Typically, water is drawn from the surrounding environment, such as a nearby stream or lake, and the water is eventually returned to the stream or lake. [0003] The problem is that water is often contaminated with chemicals and / or other waste products from industrial processes, forming wastewater. Accordingly, it is often desirable to treat such wastewater to remove some or all of the contaminants prior to returning such wastewater to the environment. [0004] One particular sou...
