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

The present disclosure relates to distillation apparatus, especially such apparatus that may be deployed within a commercial, domestic or near-Domestic situation to provide distilled water on demand. The distillation apparatus comprising an evaporation chamber, a condensation chamber, a heat source, the heat source being arranged to supply heat to at least part of the evaporation chamber, a fluid inlet, a fluid outlet, and a vapour compression pump, wherein the condensation chamber surrounds at least part of the evaporation chamber.

A water sanitizing system is disclosed and includes an inner chamber and an outer chamber disposed at least partially around the inner chamber. A lens concentrates solar energy applied to a liquid within the inner chamber. A vacuum source in communication separately with the inner chamber and the outer chamber. The vacuum source controls a pressure within the inner chamber separately from the outer chamber for controlling conversion of liquid within the inner chamber to a gas. The outer chamber, also under vacuum, is an insulative layer to prevent heat loss.

A method of degrading 1,4-dioxane in the wastewater produced during the manufacture of alkyl ether sulfates is disclosed. The method includes the steps of (a) mixing from 100 to 10,000 ppm, preferably 1,000 to 4,000 ppm of ozone with the wastewater; (b) introducing H.sub.2O.sub.2 into the wastewater in an amount of 0.01 to 10, preferably 0.1 to 0.5 molar equivalents of H.sub.2O.sub.2 to ozone, and (c) mixing the ozone, H.sub.2O.sub.2, and wastewater to generate hydroxyl radicals reactive with the 1,4-dioxane, without the addition of a metal catalyst. The hydroxyl radicals react with the 1,4-dioxane and degrade it into carbon dioxide, water and/or carbonate. The method is effective to reduce a concentration of 1,4-dioxane in the wastewater from a range of about 10 ppm to about 1000 ppm of dioxane down to less than 5 ppb of 1,4-dioxane after treatment. The method is also effective for removing hydrocarbon species that may be present in the wastewater.

A water purification system comprising a salvage pump, a vacuum assembly, and a clean water assembly. The salvage pump is configured to draw water from a water source. The vacuum assembly is configured to remove solutes from the water via vacuum evaporation. The clean water assembly is configured to remove non-soluble particles and/or bacteria from the water.

In an example method, first electrical power is generated using one or more solar panels, and a water level rise of a sea is mitigated, at least in part, using a water processing system that is at least partially powered by the first electrical power. Mitigating the water level rise of the sea includes extracting saline water from the sea, desalinating the saline water, directing the desalinated water to one or more turbine generators, generating second electrical power using the one or more turbine generators, and directing the desalinated water from the one or more turbine generators into one or more aquifers. The one or more aquifers are hydraulically isolated from the sea.

A liquid separation system includes an inner chamber and an outer chamber disposed at least partially around the inner chamber. A vacuum source in communication separately with the inner chamber and the outer chamber controls a pressure within the inner chamber separately from the outer chamber for controlling conversion of liquid within the inner chamber to a gas.

The present application provides a method for recycling selenium sources in a selenium-enriched yeast fermentation process, and a treatment system for selenium-containing wastewater. The method includes: step S1, performing separation and concentration treatments on selenium-containing wastewater produced in a selenium-enriched yeast fermentation process, so as to obtain a selenium-containing concentrated solution; step S2, adjusting a selenium content of the selenium-containing concentrated solution to a predetermined selenium content, so as to obtain a selenium-containing nutrient solution; and step S3, adding the selenium-containing nutrient solution into a selenium-enriched yeast fermentation reaction, so as to realize the recycling of the selenium source.
