A biofilter design tool for hydrogen sulfide removal calculations
(2012-08)
Biofilters have been used for decades in the management of nuisance odors that are emitted from the collection and treatment systems of municipal sewage works. Typically hydrogen sulfide (H2S) has been identified as the ...
An Empirical Assessment of U.S. State-Level Immigration and Environmental Emissions
(2010-03)
This paper uses U.S. state-level data for CO, NO2, SO2, and PM10 emissions and a STIRPAT-inspired model to provide empirical evidence discrediting, at least in part, the restrictionist perspective on the immigration-environment ...
Hydrologic Design Aid For Urban Grass Filter Strip
(Wiley, 2015-11-19)
A set of generalised charts are presented in this article as a design aid for hydrologic sizing of grass filter strips. The charts express the volume of runoff and the peak flow rate from a grass strip and the residence ...
Efficiency of membrane technology, activated charcoal, and a micelle-clay complex for removal of the acidic pharmaceutical mefenamic acid.
(2013-08)
The efficiency of sequential advanced membrane technology wastewater treatment plant towards removal of a widely used non-steroid anti-inflammatory drug (NSAID) mefenamic acid was investigated. The sequential system included ...
Diazepam stability in wastewater and removal by advanced membrane technology, activated carbon, and micelle-clay complex
(2016)
Stability and removal of the anti-anxiety drug diazepam (valium) from spiked wastewater samples were studied. An advanced wastewater treatment plant (WWTP), utilizing ultrafiltration (UF), activated charcoal (AC), and ...
A health risk assessment of Arabian incense (Bakhour) smoke in the United Arab Emirates
(2015-04)
Burning Arabian incense (Bakhour) is a common practice in the Middle East and Arabian Gulf. Although the incense generates large amounts of chemicals and air pollutants, little is known with regard to the nature of these ...
Prediction of minimum factor of safety against slope failure in clayey soils using artificial neural network
(2015)
This paper presents prediction of minimum factor of safety (FS) against slope failure in clayey soils using artificial neural network (ANN). Two multilayer perceptron ANN models were used to predict the minimum factor of ...
Phosphorus Recovery from the Wastewater Stream - Necessity and Possibilities
(Taylor & Francis, 2016)
The annual demand of phosphorus (P) for fertilizer use is more than 550,000 t in Germany. Several of the input streams like mineral fertilizer produced from phosphate rock or sewage sludge are problematic due to contamination ...
Concentrating solar power (CSP) system integrated with MED-RO hybrid desalination
(2014-03)
Renewable energy technologies, in particular concentrating solar power (CSP), are becoming more and more interesting for powering water desalination system. Moving from a European Community funded project called MATS, ...
Dynamic modeling and analysis of biotrickling filters in continuous operation for H2S remova
(2014-12)
A number of important biotrickling filter (BTF) models are reviewed. For our study, a theoretical model, based on H2S removal in a differential BTF under batch mode, was selected among the models reviewed. Using a cascade ...
