A vacuum distillation apparatus for producing treated water from a supply of seed water, the apparatus including: an evaporation chamber for receiving and evaporating the seed water; a heat source for supplying heat to the evaporation chamber; a condensation chamber in fluid communication with the evaporation chamber for receiving and condensing the evaporated seed water; a pressure reducer in communication with the evaporation chamber for promoting evaporation of the seed water; and at least one cooling member disposed within the condensation chamber on which the evaporated seed water can condense, the cooling member being arranged to transfer condensed vapour for collection at a treated water outlet.

The present invention relates to a system and method using a reservoir specially designed for desalinating sea water. The invention makes it possible to evaporate the sea water and condense the resulting vapor at low pressure. Discharges into the sea resulting from said desalination operations have a low salt concentration. The present system and method can be used to recycle energy, even energy which is difficult to recycle, for desalinating sea water, or can be combined with other desalination techniques, for example such as MSF evaporation or MED distillation.

The present invention relates to a garbage dehumidifying device and a method thereof, wherein the garbage dehumidifying device comprises the following: an airtight first chamber (1) provided therein with the wet waste, a heater (14) for heating said first chamber, an airtight second chamber (8) connected with the first chamber so as to maintain the vacuum communication and a vacuum pump (10) connected to at least one of said chambers for creating vacuum inside said chambers.

Techniques are described herein for using a high-pressure reactor to separate clean water from dirty water without filtration and to extract and concentrate contaminants from dirty water for use as a fuel. In particular, techniques and systems are described for separating water from hydrocarbon contaminates, other BTU-laden compounds, and dissolved minerals, while also boiling water and condensing the resulting steam into distilled water. In addition, system in which the described techniques are performed can be used as a high-pressure pump for moving the separated hydrocarbon contaminates forward into other processes, such as a high-pressure reactor or incinerator.

The present invention provides a process for recovering glycol from a process stream comprising glycol, water, dissolved salts, and hydrocarbons. The process comprises subjecting the process stream to a salt-enrichment process to obtain a salt-enriched stream having a salt concentration higher than salt concentration of the process stream, and a salt-reduced stream; subjecting the salt-enriched stream to a glycol reclaiming process to separate the salts and at least a portion of the hydrocarbons from the salt enriched stream to obtain a substantially salt-free water-glycol stream; and blending the salt reduced stream from the salt-enrichment process with the substantially salt-free stream to produce a reclaimed water-glycol stream.
