Patent number: 9505635Abstract: The wastewater filtration system and method relates to systems and methods that use Ruba Al-Khali Saudi sand as the filtration media in systems for treating industrial wastewater. Ruba Al-Khali Saudi sand is effective in removing organic dyes, particularly rhodamine B, from the wastewater. The method includes bringing wastewater having an organic dye constituent into contact with the Saudi sand for a period of time sufficient to adsorb the organic dye. The system may include a batch reactor, such as a fixed bed or moving bed reactor, or a continuous flow reactor, such as a column reactor. When a batch reactor is used, the method may benefit from shaking or agitating the filtration media, particularly in the dark or under low ambient light conditions. The method may include regenerating the Saudi sand after use by heating the filtration media.Type: GrantFiled: December 22, 2014Date of Patent: November 29, 2016Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Mohammed Ashraf Gondal, Xiaofeng Chang, Mohammad Ashraf Ali, Mohamed Abdulkader Dastageer, Syed M.

Patent number: 9416800Abstract: A carrier-gas mixture is directed through a fluid flow path in a combined heat and mass transfer device, which can be operated at sub-atmospheric pressure. Heat and mass are transferred from or to the carrier-gas mixture via interaction with a liquid composition that includes a vaporizable component in a liquid state to substantially change the content of the vaporizable component in the carrier-gas mixture via evaporation or condensation. The mass flow rate of the carrier-gas mixture is varied by extracting or injecting the carrier-gas mixture from at least one intermediate location in the fluid flow path, and/or the mass flow rate of the liquid composition is varied by extracting or injecting the liquid composition from at least one intermediate location in the fluid flow path; and the flow of the carrier-gas mixture or the liquid composition is regulated to reduce the average local enthalpy pinch in the device.Type: GrantFiled: June 24, 2013Date of Patent: August 16, 2016Assignees: Massachusetts Institute of Technology, King Fahd University of Petroleum MineralsInventors: Prakash Narayan Govindan, Gregory P.

Publication number: 20150174567Abstract: The hybrid photocatalyst for wastewater remediation is a composite of rhodamine B and BiOBr. The rhodamine B has a concentration between about 0.1 wt % and about 1 wt % of the overall photocatalyst. The hybrid photocatalyst is made by immersing a BiOBr semiconductor in an aqueous rhodamine B solution to form the hybrid photocatalyst by sorption of the rhodamine B by the BiOBr semiconductor. In use, the hybrid photocatalyst is added to wastewater containing at least one contaminant, such as methyl orange (sodium 4-[(4-dimethylamino)phenyldiazenyl]benzenesulfonate), to form a suspension of the hybrid photocatalyst and the at least one contaminant. The suspension is then exposed to visible to light to form a slurry containing a reaction mixture in the wastewater. The slurry is then filtered to remove the reaction mixture.Type: ApplicationFiled: December 22, 2014Publication date: June 25, 2015Applicants: MASSACHUSETTS INSTITUTE OF TECHNOLOGY, KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: MOHAMMED ASHRAF GONDAL, XIAOFENG CHANG, MOHAMMAD ASHRAF ALI, MOHAMED ABDULKADER DASTAGEER, SYED M.

Patent number: 8647477Abstract: Water can be separated from a liquid composition (e.g., salt water) by directing a carrier gas flow through an evaporator and directly contacting the carrier gas flow with the liquid composition in the evaporator to humidify the carrier gas with water evaporated from the liquid composition, producing a humidified gas flow, which is then compressed by injecting a fluid that includes steam and/or an organic compound at an elevated pressure at least five times greater than the pressure in the evaporator and at a temperature at least as high as a saturation temperature of the steam/organic compound at the elevated pressure of the fluid. After being compressed, the humidified gas flow is directed through at least one condenser where water is condensed from the compressed humidified gas flow and collected; and the dehumidified gas flow is re-circulated back through the evaporator for reuse as the carrier gas.Type: GrantFiled: February 15, 2011Date of Patent: February 11, 2014Assignees: Massachusetts Institute of Technology, King Fahd University of Petroleum and MineralsInventors: Prakash N.
