Abstract: Provided herein are water harvesting systems, as well as methods using such systems, for capturing water from surrounding air. The systems and methods use water capture materials to adsorb water from the air. For example, the water capture materials may be metal-organic-frameworks. The systems and methods desorb this water in the form of water vapor, and the water vapor is condensed into liquid water and collected. The liquid water is suitable for use as drinking water.

Abstract: Novel microwave ovens and methods of using and manufacturing the same. Some microwave ovens include multiple doors and/or control keypads.

Abstract: A process for disinfecting a treatment fluid is disclosed, including the step of admixing an aqueous solution comprising two or more oxidants generated via electrolysis of a salt solution with a treatment fluid. The mixed oxidants may be generated on site, using a containerized system.

Abstract: A method of recovering oil from oil-based sludge including the steps of homogenizing an oil-rich phase, a water-rich phase, and a solids-rich phase of an oil-based sludge, removing particulates from the oil-based sludge as the sludge traverses a shaker screen, heating the sludge, injecting a chemical into the heated sludge and mixing the chemical with the heated sludge, separating the phases of the chemically-treated sludge into a solids component stream, a water component stream, a first oil component stream, and a gas component stream, removing solids from the first oil component stream with a decanting centrifuge to form a second oil component stream, and removing water and solids from the second oil component stream with a disk stack centrifuge.

Abstract: An apparatus for transferring a viscous fluid including waxy solids includes a mobile platform, a support member having a first end coupled to the platform and a second end, a pump unit coupled to the second end of the support member, wherein the pump unit can be raised and lowered with respect to the second end, wherein the pump unit includes a recirculation system selectively operable to break down waxy solids prior to transfer of the fluid, and an outlet in fluid communication with a collection tank.

Abstract: A modular apparatus having certain processing equipment mounted on portable skids that are adaptable and versatile to permit customized arrangement for oil-recovery processing of a wide range of oil-base sludge compositions in a cost-efficient manner. In one aspect, the invention is directed to a modular apparatus optimally configured for oil recovery of sludge having a high concentration of low density solids, wherein the apparatus may include a pumping skid, a shaker skid, a heating skid, a chemical skid, a phase separator skid, a gas purification skid, a decanter skid, and an oil purification skid. In another aspect, the invention is directed to a modular apparatus optimally configured for oil recovery of sludge having a high concentration of high density solids, wherein the apparatus may include a pumping skid, a shaker skid, a heating skid, a first chemical skid, a decanter skid, a second chemical skid, a phase separator skid, a gas purification skid, and an oil purification skid.
