A system and process is disclosed for treating foul condensate such as foul condensate produced in a Kraft pulp mill. Foul condensate is directed through a steam stripper to produce a clean condensate that is partially evaporated by a volatile rich vapor stream produced by the steam stripper in the course of treating the foul condensate. Vapor produced by the evaporation of the clean condensate is directed to one or more electrically driven mechanical vapor re-compressors that produce the steam that is used in the steam stripper.

A vapor compression distillation assembly for distilling influent liquid, the vapor compression distillation assembly comprising a housing defining an interior and having an inlet for influent liquid, an evaporator and a condenser provided within the housing interior, an outlet for distillate, and at least one compressor fluidly coupled with the housing interior.

A system for treating a biologically contaminated water stream to lyse pathogens within the biologically contaminated water stream is provided. The system can include a flash vessel configured to receive a biologically contaminated water stream and to separate steam from liquid in the biologically contaminated water stream, a blower configured to receive the separated steam from the flash vessel and compress the separated steam for reintroduction into the biologically contaminated water stream, a circulation pump configured to receive the separated liquid from the flash vessel and to pressurize the separated liquid into a circulation stream, a preheater exchanger configured to receive treated water from the circulation stream and preheat the biologically contaminated water stream, and a pressure drop device configured to lower the pressure of the biologically contaminated water stream prior to receipt by the flash vessel.

An apparatus for generating purified liquid from an input liquid, comprises, an evaporation chamber, wherein the evaporation chamber is flooded with the input liquid; and a condensation chamber having channels, wherein the channels are disposed in the input liquid, wherein liquid-saturated gases are generated from the input liquid in the evaporation chamber, wherein the liquid-saturated gases are guided into a first end of the channels, and wherein the purified liquid is outputted at a second end of the channels.

A mechanical vapor recompression system and method thereof. The system comprises: an evaporator (20), a first cavity (30), a first fluid collection area (31), a second cavity (32) and a blowing type pump (33), the evaporator (20) having a high temperature fluid reception channel (21a) and a low temperature fluid reception channel (21b); the method comprises: enabling a first fluid to flow from a vapor source (10) to the high temperature fluid reception channel (21a) of the evaporator (20), enabling liquid water collected from a first fluid supply to flow to the low temperature reception channel (21b), and transferring heat of vaporous water in the high temperature reception channel (21a) to the liquid water collected in the low temperature reception channel (21b); converting at least a part of the liquid water collected in the low temperature reception channel (21b) to vaporous water, and returning the further heated vaporous water to the vapor source (10).

A multi-functional slurry processing system (VARCOR) and associated methods is disclosed. The present examples provide a multi-functional slurry processing system incorporating systems and methods for separating liquid and solid components in slurries. In particular the systems and methods described herein produce clean water, dried solids, and potential concentration of desirable constituents with a boiling point lower than water. At least one example of the multi-functional slurry processing system provides a self-contained processing facility configured to efficiently convert high water-content slurries into its constituent solid and liquid fractions and subsequently generating and collecting clean water and concentrating desirable constituents with a boiling point lower than water. The multi-functional slurry processing system advantageously applies thermodynamic principles in a system which may include various combinations of a preheater, a degassing unit, a dryer, a steam filter, a compressor, a concentrating tower, and a condensation unit.
