Abstract: Applying the concept that microbes utilize the organic substances in the influent, generate metabolic products, and reutilize these products in a typical activated sludge system, a double substrate model is proposed. In ...

Abstract: This paper presents a mathematical model describing the process of vacuum deodorization of digested sludge odorants. This model is based on a mass balance of odorant substance drawn around the vacuum chamber, assuming first ...

Abstract: A novel receptor-oriented methodology has been developed to apportion source contributions of the nitrogen species measured in the south coast air quality basin (SoCAB) in the 1987 southern California air quality study ...

Abstract: Experimental studies with granular bed filters composed of sized metallic granules have demonstrated their use in aerosol filtration. However, the effectiveness of metallic membrane filters against bioaerosols has not been ...
