An aqueous stream cleaning system including a circulation pump to receive a waste fluid and/or a concentrated liquid bottoms stream, and expel a circulation stream. The aqueous stream cleaning system can also include a primary heat exchanger to receive the circulation stream from the circulation pump. The primary heat exchanger can have a plurality of heat exchange plates that define an internal surface area for heat transfer from a distillate stream to the circulation stream to produce a cooled distillate stream and a heated circulation stream. The plurality of heat exchange plates can be spaced to facilitate free flow of solids in the circulation stream between the plurality of heat exchange plates. A mass flow rate and pressure of the circulation stream can be configured to minimize build-up of solids in the primary heat exchanger. The aqueous stream cleaning system can further include an evaporation unit to receive the heated circulation stream from the primary heat exchanger. The distillate stream is formed when steam in the heated circulation stream evaporates in the evaporation unit, and the concentrated liquid bottoms stream is formed from a portion of the heated circulation stream that does not evaporate.

A system has a first plate heat exchanger at a first pressure to heat a fluid containing dissolved solids to form a heated fluid at a temperature below the boiling point of the fluid. A vaporization chamber is connected to the first plate heat exchanger. The vaporization chamber is at a second pressure below the first pressure. The vaporization chamber receives the heated fluid and produces a gaseous component substantially free of dissolved solids and a solids component. A compressor is connected to the vaporization chamber. The compressor receives the gaseous component and produces a fluidic output. The first plate heat exchanger has plates forming chambers. A manifold arrangement distributes an unprocessed fluid from the vaporization chamber to a first subset of the chambers and distributes the fluidic output from the compressor to a second subset of the chambers.

The present disclosure is drawn to evaporation panel assemblies, systems, and methods. For example, a modular evaporation panel system can include a plurality of evaporation panels with individual evaporation panels including evaporation shelves that are laterally elongated, vertically stacked, and spaced apart; vertical support columns positioned along the evaporation shelves to vertically support and separate the evaporation shelves; female-receiving openings defined by multiple evaporation shelves and multiple support columns; and male connectors positioned at lateral ends of the evaporation panels. The male connectors can be releasably receivable by the female-receiving openings of an adjacent evaporation panel, thereby providing modular assembly and disassembly of multiple evaporation panels relative to one another.
