Rational Design of Next-generation Nanomaterials and Nanodevices for Water Applications
Despite the fact that nanotechnology has been present for a few decades, there is a big gap between what nanotechnology is perceived and what nanotechnology can truly offer in all sectors of water. The question to be answered is _x0018_what more can we expect from nanotechnology_x0019_ in the water field? The rational nano-design starts with well-defined problem definitions, necessitates interdisciplinary approaches, involves ...

Evaluation of GHG Emissions from Septic Systems
The emission rates of greenhouse gases (GHGs) from individual onsite septic systems used for the management of domestic wastewater were determined in this study. A static flux chamber method was used to determine the emission rates of methane, carbon dioxide, and nitrous oxide gases from eight septic tanks and two soil dispersal systems. A technique developed for the measurement of gas flow and concentration at clean-out ports was used to ...

Optimizing Filtration and Disinfection Systems with a Risk-Based Approach
Treated wastewater effluents contain high concentrations of particles; many of these particles are large (with diameters greater than 100 μm) and consist of densely-packed bacterial cells. Microorganisms occluded in wastewater particles can be difficult to inactivate in chlorine disinfection systems, as the chlorine must first diffuse through the macro- and microscopic pore spaces prior to inactivating the occluded microorganisms. The impact ...
