Publication number: 20190241444Abstract: A solar powered humidification-dehumidification desalination system comprises or consists of a supply of seawater or brackish water referred to hereinafter as saline water passing through a dehumidifier condenser. The saline water passes a dehumidifier condenser and is preheated in the dehumidifier condenser or immediately before the dehumidifier condenser and thereafter due to the condensation process. A single humidification stage or multiple humidification stages include humidifier(s) and respective solar collectors. The solar collectors heat water and the heated water passes through the respective dehumidifiers to evaporate the preheated saline water to thereby separate pure water from the brine. The heated air is reheated and recirculated through the humidifying stages and dehumidifier and the desalinated water from condensation in the dehumidifier is collected and processed.Type: ApplicationFiled: February 8, 2018Publication date: August 8, 2019Inventors: Fahad A.

Patent number: 9643102Abstract: The humidification-dehumidification desalination system includes a humidifier, a dehumidifier, and a carrier gas that is humidified in the humidifier and condensed in the dehumidifier to produce purified water. The humidifier preferably includes multiple stages in a staircase configuration in which at least one stage has a perforated or porous plate and the carrier gas is bubbled through the bottom of the plate into the “liquid to be purified” atop the plate. The dehumidifier may also include multiple stages in a staircase configuration in which at least one stage has a perforated or porous plate and the carrier gas is bubbled through the bottom of the plate into the purified liquid atop the plate. In both the humidifier and the dehumidifier, the liquid travels downward from one stage to the next stage. The system may be operated in a closed loop, so that the carrier gas is recirculated from the dehumidifier to the humidifier.Type: GrantFiled: June 5, 2014Date of Patent: May 9, 2017Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Fahad A.
