CHAPTER 7: Nanomaterials for Heavy Metal Removal
Wastewater containing heavy metal ions is considered as a serious environmental problem for human society. Advances in nanoscale science and engineering provide new opportunities to develop more cost-effective and environmentally acceptable water treatment technologies. Nanomaterials have a number of physicochemical properties that make them particularly attractive as nanoadsorbents for decontamination [...]
Water Collection from Air Humidity in Bahrain
The Kingdom of Bahrain falls geographically in one of the driest regions in the world. Conventional fresh surface water bodies, such as rivers and lakes, are nonexistent and for water consumption, Bahrain prominently relies on the desalination of sea water. This paper presents an ongoing project that is being pursued [...]
Concomitant of global warming and land reclamation: Designing a new interface between human kind and sea
The Kingdom of Bahrain, as many other countries suffers from land scarcity, caused by the overpopulation. This directed them to substitute city designing, based on fundamentals of sustainability. Unfortunately, Government had only one quick solution to accommodate the swift urbanization and that was land reclamation upon the surrounding Gulf water. [...]
Comparing the total coliform and fecal coliform for recreational waters in public swimming areas in the Kingdom of Bahrain
The Kingdom of Bahrain has an annual rainfall of about 78 mm with limited surface water resources and poor underground recharge. The rapid increase in urbanization, during the last 20 years, has increased the demands for additional water supplies. Recycling of such limited resources would also necessitate monitoring effluents coming [...]
Who is the bigger culprit? Studying impacts of traffic and land use on noise levels in CBD area of Karachi, Pakistan
The trend of urbanization has attracted increased attention towards urban areas around the world. Central business districts (CBDs) serve as the core of commercial activities of urban areas and are often associated with high-density population. Noise pollution in urban areas, especially CBDs, is considered as an important issue for planners [...]
Green and ecofriendly materials for the remediation of inorganic and organic pollutants in water
The widespread of organic and inorganic pollutants in wastewater from various industries, are responsible for serious environmental problems meanwhile represent a danger for human being. Therefore, the search of cost-effective methods of wastewater treatment containing in particular heavy metals and dyes, become of great importance. Noteworthy, adsorption has proven to [...]
Accelerating the transformation to a green university: University of Bahrain experience
Many universities are striving to have an environmental impact on the society as they are considered as small communities aiming to be eco-friendly and having low CO2 emission. This concept has been emerging after the worldwide concern on the ozone depletion issue and global warming. As a result, many titles [...]
Application of central composite design to optimize culture conditions of chlorella vulgaris in a batch photobioreactor: An efficient modeling approach
Microalgae cultivation and their use is a promising approach for integrated CO2 biofixation, wastewater treatment and renewable energy production. To develop such an important technology, there is a need to optimize the culture conditions, maximizing CO2 consumption, degrading the nutrients present in the wastewater and maximise the microalgae biomass production. [...]
The smart mosque of the Arabian Gulf: Solutions from the past for a sustainable, energy-efficient Mosque
This study examines the smart mosque as a concept, developed through innovations in materials and technologies adopted to provide thermal comfort conditions and energy- efficient environments, in order to promote a sustainable mosque. The paper first provides a theoretical underpinning of the smart solutions applied in historical mosques with a [...]
Mineral compositions of tap, filtered and bottled waters in Bahrain
The concentrations of the minerals magnesium (Mg2+), calcium (Ca2+), sodium (Na+) and potassium(K+) were determined in tap, filtered and bottled waters in Bahrain using atomic absorption spectroscopy. Tap and filtered water samples were obtained from the households of ten different cities in Bahrain, while twenty different commercial brands of bottled [...]
