This paper provides an overview of the Special Issue on Wastewater Treatment and Reuse: Past, Present, and Future. The papers selected for publication include advanced wastewater treatment and monitoring technologies, such as membrane bioreactors, electrochemical systems; denitrifying biofilters, and disinfection technologies. The Issue also contains articles related to best management practice...

This article presents an evaluation of the electronic nose technology as an alternative to sensory analysis for assessing the effectiveness of biofilters. An AromaScan A32S electronic nose and a human panel at Duke University’s Taste and Smell Research Lab were used to measure typical volatile compounds from swine confinement buildings. Chemometrics techniques were employed to predict the olfac...

Two pilot scale biofiltration systems were constructed and installed at the University College Dublin Research Farm, Lyons Estate. Experimental units consisting of two pens in a 12 pen pig house were sealed off from other pens. Air from each pen was extracted and treated separately in two biofiltration systems. Wood chips larger than 20 mm were selected as the medium for biofiltration system 1,...

Laboratory scale experiments and field studies were performed to evaluate the feasibility of biofilters for sequential removal of H2S and VOCs from wastewater treatment plant waste air. The biofilter was designed for spatially separated removal of pollutants in order to mitigate effects of acid production resulting from H2S oxidation. The inlet section of the upflow units was designated for H2S...

The degradation of water resources is related to anthropic actions such as rapid urbanization and industrial agricultural activities with inefficient land use occupation management. Water pollution caused by organic inorganic contaminants represents a current challenge for researchers humanity. One the techniques used remove pollutants from aquatic environments bioremediation, through metabolis...
