Research in Environmental and Water Resources Engineering (EWRE) Program focuses on solving the environmental challenges faced by the Gulf Region.
Research projects cover a wide variety of fields, including hydraulic and hydrology, water resources engineering, water and waste water treatment plant design, air quality and biogeochemistry of contaminated waters. Research are carried out to achieve improved understanding on how to protect the environment and public health and safety from the adverse effects of pollution, and to ensure that nature's ecosystems are not adversely affected as they are used to benefit humanity.
The dump and landfill sites located throughout UAE have received a mixture of waste, and waste generation is expected to triple by 2030. The increased amount of wastes requires sustainable landfills. Landfill leachate is composed of liquid that drains from a landfill. Leachate consists of high organic and inorganic materials with high COD and if not managed properly, can pollute environment.
The processes currently used to treat leachate are nitrification/denitrification, air stripping, coagulation/flocculation, settling, reverse osmosis, active carbon adsorption, and advanced oxidation process. However, these techniques are not economical. Furthermore leachate can be sent to Waste Water Treatment Plants, although high metal content of the leachate may inhibit biological activity in aeration tank. Therefore new methodologies should be investigated to remove organics and inorganics at the same time. Fenton process reduces metal and chemical oxygen demand (COD) concentrations in water and wastewater. COD reduction by packed bed bioreactors has been demonstrated as well. The aim of this study will be to demonstrate the removal of large quantities of metals and organics with zero valent iron coated sand column coupled with activated sludge immobilized pack bed reactors. This novel leachate treatment will help to develop and implement sustainable landfills management.

The aim of the LCA for this work is to lower environmental impacts of the aluminum sandwich panels for aerospace and civil applications.
The objectives of LCA are:
|Production||Material-specific energy consumption during panel production|
Transport distance, fuel consumption, vehicle types
|Service||Fatigue reliability analysis (time-dependent fatigue reliability, fatigue damage) for assessing and predicting lifetime performance of aluminum panel|
|Recovery/disposal||Recycle options for panels|
