Abstract: Disclosed herein is a solar thermal osmosis desalination system comprising a forward osmosis subsystem and a reverse osmosis subsystem where the forward osmosis subsystem is configured to receive solar thermal heat and generate power that can be used to operate the reverse osmosis subsystem.

Abstract: A gas hydrate desalination system that includes a reactor with a detachable water jacket and thermocouples. The reactor has a detachable lid having a liquid inlet, a gas inlet, sapphire glass lenses, and lid cameras. An exit concentrate channel is provided at a bottom of the reactor. A mixing unit of the system includes a liquid storage tank connected to the reactor through the liquid inlet, and a gas feed cylinder connected the reactor through the gas inlet. A resolving unit of the system includes a sieve filter column for filtering brine from gas hydrate. The sieve filter column is connected to the exit concentrate channel and a first fraction column, which is connected to a brine column. The channel is further connected to a second fraction column, which is connected to the brine column for separating freshwater from the gas hydrate.

Abstract: A Brayton cycle adsorption desalination system includes an adsorption desalination system including an evaporator for evaporating saline water to obtain water vapor, an adsorbent bed for adsorbing and desorbing the water vapor, and a condenser for condensing the water vapor to obtain distilled water. The Brayton cycle adsorption desalination system further includes a Brayton cycle system including a primary heat exchanger (PHE) and a cooler configured to cool an exhaust from the PHE. The Brayton cycle system and the adsorption desalination system are connected at the PHE so that the PHE is configured to function as a heat source for the adsorbent bed. The Brayton cycle system and the adsorption desalination system are connected at the cooler so that the evaporator is configured to absorb heat rejected from the cooler.
