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 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.

Treatment of wastewater and particularly relates to a technique for wastewater treatment using renewable energy (RE) which is sole solar energy (SE). In bench scale experiment, a device is constructed to consist of two fixed upper and lower glass Petri dishes. Another device consists of plastic containers and both devices with the same volume of wastewater in the upper and distilled water in the lower container. The first device is placed on the bench beside window to be exposed to sunlight at room temperature and the other device is put outdoors under direct sunlight during daytime. A build-up of small circular water droplets starts to appear on the external bottom of upper container. Water droplets are allowed to fall freely in the lower container, pH of droplets water is about 7.1. Yield of freshwater is at a rate of approximately 300 ml freshwater from 400 ml wastewater per 48 hours.

This disclosure concerns a system and a method for removing dissolved solids from liquids. Specific implementations concern desalinating water. The system may comprise a blower, such as a thermal fan/compressor, configured to atomize a solid-bearing liquid to produce a hot, humid gas containing dissolved solids; a gas-solid separator configured to receive hot, humid gas containing entrained dissolved solids from the blower to separate the solids from the humid gas and to transmit the humid gas with solids removed through an exit port; a heater configured to heat the hot, humid gas received from the exit port of the gas-solid separator; and a condenser configured to receive heated humid gas from the heater and to condense solids-free liquid therefrom. The thermal fan/compressor may comprise a plurality of nozzles with outlets positioned adjacent atomization apertures across which a solid-bearing liquid flows and through which gas exiting the nozzles passes.
