Abstract: A portable assembly for extracting water from air for provision of potable water includes a housing that defines an internal space. The housing is vented. A plurality of grasps is coupled to the housing. A power module, a condensing unit and a reservoir are coupled to the housing and positioned in the internal space. The condensing unit is operationally coupled to the power module. The reservoir is positioned below the condensing unit and is fluidically coupled to the condensing unit. The grasps are configured to couple to a user, such that the housing is coupled to the user for transport. An evaporator coil of the condensing unit is configured to contact air that enters the internal space. Water vapor in the air condenses on the evaporator coil and falls to a bottom of the condensing unit. Liquid water that is positioned on the bottom of the condensing unit flows to and is collected in the reservoir.

Abstract: A sewage treatment system uses a multi-stage process to treat waste materials. Sewage is contained in a first tank, from which liquid waste is filtered and transferred to a second tank, where the first tank retains solid waste. The second tank may contain a plurality of chambers, with the chambers connected using ports for fluid communication. Liquid waste in the second tank undergoes aerobic digestion, where an aeration device may aid in the digestion process. The second tank may also include a UV light source to reduce bacteria. The treated liquid from the second tank may be clean enough to be discharged directly into a leach field which would not meet standards for conventional leach fields.

Abstract: Mosquitoes are vectors for many dangerous diseases such as Malaria, Dengue, Yellow Fever, West Nile, and those from Zika virus etc. Mosquito transmitted diseases occur mostly in tropical, developing countries and create public health crises due to lack of adequate resources and rapid transmission. Malaria took 429,000 lives in 2015 and the impending Zika crisis shows the need for effective mosquito control. Nearly half of the world's population is at risk of malaria. Current mosquito control efforts focus on reducing the population of mosquitoes. The many mosquito control strategies such as using tarps to suffocate larvae, insecticides, genetic engineering, biocontrol using fish etc. have substantial drawbacks. These methods are environmentally hazardous, expensive, inefficient, hard to maintain, bulky, or energy intensive. Mosquitoes breed in stagnant water. They cannot breed in agitated water or running water. Thus, this patent describes water agitators that are environmentally safe, efficient, and cost-effective. In this patent, three water agitators prototypes are presented. They are self-sustaining, lightweight, mobile, and have minimal potential for misuse. The agitators consume solar energy. They are self propelling and do not require maintenance, such as changing parts. They are designed to be inexpensive, reusable, and mass-producible. These agitators can cover a much larger area of water compared to their size. They target small to large water areas. Agitators are versatile and can be used in flower vases, open rain jars, tire tracks, mining pits, small ponds etc.

Abstract: The hybrid desalination system is a desalination system for seawater which uses both filtering and treatment from a reverse osmosis filter system as well as evaporative distillation for the production of potable water. The hybrid desalination system includes a recovery system, which may be a reverse osmosis system, a forward osmosis system, or a combination thereof, for at least partially desalinating a volume of saltwater and outputting a treated fluid. A boiler is in fluid communication with the recovery system for receiving the treated fluid and producing pure water by evaporative desalination. The boiler includes an internal heating coil for passing a heated working fluid therethrough. A collection tank is in communication with to the boiler for receiving the pure water. At least one solar parabolic trough is in fluid communication with the internal heating coil of the boiler for heating the heated working fluid.

Abstract: Methods and systems are provided for disinfecting water mains using ultraviolet (UV) light and advanced oxidation processes. One or more UV light sources are provided and secured to a movable device that moves axially in a pipe. The frequency and intensity of the UV light is determined based on characteristics of the pipe, such as its material and size. The rate at which the movable device moves through the pipe is also determined so that the interior surface of the pipe is properly disinfected. The movable device is remotely caused to move through the pipe. An oxidant supply component having a dispensing portion dispenses an oxidizing agent into the pipe. A portion of the emitted UV light may convert the dispensed oxidizing agent into additional oxidizing agents that further disinfect the pipe.
