A sorbent device based on a porous membrane bag (e.g., porous propylene membrane bag) encapsulated alkaline-modified zeolite (e.g., alkaline-treated USY zeolite). A process for removing heavy metals, such as Cd(II), Cr(III), and Pb(II) from an aqueous solution or an industrial wastewater samples with the sorbent device is provided. A method for preparing the alkaline-modified zeolite is also described.

A high pressure, high temperature spray cooling system for heat transfer. The system includes: a supply tank having a heater and a high pressure pump; and a spray chamber spaced apart from the supply tank. The spray chamber has a workpiece receiving bed and a nozzle spaced apart from the workpiece receiving bed. The supply line has a first supply line end and a second supply line end. The first supply line end is connected to the supply tank and the second supply line end is connected to the nozzle so that the contents within the supply tank are supplied to the nozzle through the supply line at a high pressure to cool a workpiece on the workpiece receiving bed.

An irrigation system is configured with a sprinkler module resting on at least two guide rails supported in a parallel arrangement by a plurality of legs, with the legs forming a rack used to provide a guideway for a sprinkler module along the guide rails, with the guide rails and cross supports arranged to form a plane. An adjustment is provided for positioning the plane of the guide rails and cross supports at tilt or angular adjustment of the plane to provide a selected alignment of the plane with a terrain location of the irrigation system. The sprinkler module is connectable to a water source capable of providing a water supply for discharge through the sprinkler modules; and at least one tracking wheel drive motor, such as a water powered drive motor or an electric motor, is provided for driving the sprinkler module along the guide rails.

The solar-powered system for generating steam and distilled water includes a first conduit having an inlet for receiving a feed stream of water and an outlet for dispensing heated water. The first conduit has at least one steam vent for releasing at least a first volume of steam. At least one evacuated tube collector is in fluid communication with the first conduit for solar heating of the feed stream of water to produce the heated water and the at least first volume of steam. At least one boiler is in fluid communication with the first conduit for receiving a portion of the heated water for boiling thereof to produce a second volume of steam. At least one photovoltaic panel is in electrical communication with the at least one boiler for providing power thereto, and a condenser receives the second volume of steam for condensation thereof into distilled water.

A method for extracting an analyte from a solid sample is described. The sample is sealed in a porous membrane bag, which is sonicated in an organic solvent. An extract of the analyte forms in the bag and diffuses into the organic solvent. The organic solvent containing the extract may then be concentrated and analyzed for an analyte with gas chromatography-mass spectrometry. The method does not the use of a solid sorbent material, and does not require a step of centrifuging or filtering.
