The impact of mechanically-imposed shear on clogging, fouling and energy demand for an immersed membrane bioreactor
(
MDPIAG
, 2018 , Article)
The impact of the application of mechanically-imposed shear on the propensity for fouling and clogging (or “sludging”—the agglomeration of sludge solids in the membrane channel) of an immersed flat sheet (iFS) membrane ...
Evaluating greywater and A/C condensate daily volume and water quality in urban settings
(
American Society of Agricultural and Biological Engineers
, 2011 , Conference Paper)
Due to increasing water demand as a result of population growth and improvement in living standards, many countries with arid climate are already facing water shortages that are being met by expensive desalination projects. ...
A/C condensate for water reuse: An approach towards environmental sustainability in Doha
(
American Society of Agricultural and Biological Engineers
, 2012 , Conference Paper)
A/C Condensate is a relatively untapped alternative source of water that might be readily available especially in hot arid climates. The objective of this study is to establish the feasibility of the A/C condensate as the ...
Numerical simulation of thermal buoyant wall jets
(2013 , Conference Paper)
The main focus of this study is on the near field flow and mixing characteristics of the thermal
wall jets. A numerical study of the buoyant wall jets discharged from submerged outfalls from cooling
systems of power ...
An accurate finite volume method using fourth order Adams scheme on triangular grids for the Saint-Venant System
(2013 , Conference Paper)
In this study, a new finite volume method is developed for shallow water equations on a rotating
frame. Most upwind methods, which perform well for gravity waves, lead to large oscillations and/or
numerical damping for ...
Effect of binary mixture of waste plastics on the thermal behavior of pyrolysis process
(
John Wiley and Sons Inc
, 2015 , Article)
Waste plastic is non-biodegradable material that does not decompose naturally for a long time. The pyrolysis process is a reliable method to decompose plastic wastes, which involves breaking of the heavy carbon chains and ...
CO<inf>2</inf> solubility in aqueous potassium lysinate solutions at absorber conditions
(
Academic Press
, 2017 , Article)
In this work, CO2 solubility in aqueous potassium lysinate solutions has been measured for the concentrations of (1.25–3.28) mol·kg−1 and at temperatures of (313–343) K. The vapour-liquid equilibrium data were correlated ...
Highly sensitive humidity sensor based on cadmium selenide quantum dots-polymer composites: synthesis, characterization, and effect of UV/ozone treatment
(
Springer
, 2023 , Article)
This work describes the rational design of thin film-based cadmium selenide quantum dots (CdSe) mixed with conductive polyvinylidene fluoride (PVDF), inducing PVDF-CdSe composite for potential resistive humidity-sensing ...
Bio-Based Self-Healing Concrete for Sustainable and Durable Concrete Infrastructure
(
Qatar University Press
, 2023 , Conference Paper)
In this study, bio-self-healing concrete was manufactured using a natural phenomenon called microbial-induced calcium carbonate precipitation (MICP). The bacillus cereus bacteria isolated from Qatari soil was used for this ...
Performance of Mild Steel and Corrosion-Resistant Steel Rebars in Chloride-Contaminated Concrete
(
Qatar University Press
, 2023 , Conference Paper)
Reinforced concrete (RC) infrastructure in Arabian Peninsula is subjected to harsh climatic conditions of high temperatures, humidity, and airborne chlorides and there is a high concentration of salts in seawater and soils. ...
