The present invention is a method of implementing Water Disinfection System employing a Functional Mixture, copper foam catalyst, continuous flow, UV radiation, and optical receiver pipe in order to inactivate broader range of microbial contaminants in drinking water, both for emergency purification kits and larger filtration systems. The Functional Mixture is formed when the portland cement (CaO—SiO.sub.2—Al.sub.2O.sub.3) and silicon dioxide (SiO.sub.2) combination is applied to the amalgamation of porous copper foam (Cu-Foam) and silver nitrate (AgNO.sub.3) particles, which react through the silver tree reaction (Cu+2AgNO.sub.3.fwdarw.2Ag+Cu(NO.sub.3).sub.2) after spraying over a perforated mask. The high porosity Functional Mixture is placed in UV transmissive receiver pipe with optical properties. These configurations improve the coverage, efficiency, and effectiveness of reducing broader range of pathogenic microbes in water disinfection systems over prior art. Further optimizations are available for broader range of solar lighting conditions and water flow rates.

The present disclosure describes an apparatus that may be used to generate desalinated water from a supply of untreated water using a photovoltaic cell. The front surface of the photovoltaic cell is partially enclosed to form an evaporation chamber. The front surface of the photovoltaic cell is exposed to sunlight or another light source. This exposure results in power generation by the photovoltaic cell and also heats the air in the evaporation chamber. Untreated water is subsequently introduced into the evaporation chamber. Upon contacting the heated air and the front surface of the photovoltaic cell, a portion of the untreated water evaporates to generate water vapor. The water vapor is then removed from the evaporation chamber and transported to a condensation chamber. The water vapor is cooled in the condensation chamber to yield desalinated water.

A system for generating electricity, heat, and desalinated water having a gas turbine system connected to a first electric generator, a waste heat recovery boiler (WHRB) system, a combined heat and power (CHP) generation system connected to a second electric generator, one or more solar powered energy systems, and a desalination system. The desalination system is connected to the CHP generation system and the WHRB system. The gas turbine system generates electricity and heat, the WHRB system is connected to and uses the exhaust of the gas turbine system to provide heat and steam power to the CHP generation system. The CHP generation system produces and provides electricity and heat to the desalination system, which produces product water, and at least one solar powered energy system provides thermal energy to one or more of the gas turbine system, the WHRB system, the CHP generation system, and the desalination system.

A desalination system (100) having an intake unit (110) providing seawater to a pre-treatment unit (120) connected to a reverse osmosis (RO) desalination unit (130) and a post treatment unit (150). The desalination system (100) is configured to operate without any external addition of chemicals to simplify logistics and regulation concerns. The units of the system are configured to prevent biofouling, scaling and corrosion by mechanical and biological means including high flow speeds, biological flocculation of colloids, and making the water entering the RO units inhospitable to bacteria and other organisms that cause biofouling, hence preventing their settlement and removing them with the brine. Recovery rate is lowered and energy is recovered to increase the energetic efficiency and minerals that are added to the product water are taken from the brine.

A device for the treatment of fluids has a flow-through housing, a cover, an inlet, a reactor chamber with inner walls, an outlet and UV LED radiation sources directed into the reactor chamber, and also a power supply. The device achieves a high purifying performance with less technical complexity and less installation space and needs only little electrical power. The interior of the reactor chamber has a flow-related design. The radiation sources are arranged in the fluid on or in an inner wall and a rotating fluid vortex is imparted to a fluid flowing through by the flow-related design. The radiation sources radiate radially from the outside inward and/or laterally onto the fluid vortex. At least a partial stream of the fluid in the fluid vortex passes a number of times by the radiation sources before leaving the reactor chamber.

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.

A solar water purifier is disclosed. The solar water purifier uses waste heat from a solar panel, or direct heat from the sun, to boil, evaporate, and condense water to create a stream of purified water. In one embodiment, a boiling tank is mounted under and in direct thermal contact with a solar panel to absorb waste heat. In another embodiment, a transparent wall of the boiling tank is directly exposed to solar energy. Unpurified water enters the boiling tank from an inlet tank. Once in the boiling tank, a stream of steam and water vapor leaves the tank and is allowed to condense within a condenser. The condenser is located within the inlet tank, such that the heat recovered during condensation is used to preheat the inlet water to the boiling tank.
