Abstract: This case study presents the methodology for collecting and interpreting the data for assessing the correlations among variables (required pumping frequency, user satisfaction, management district preference, user knowledge, ...

Abstract: The success of composting as one of the alternatives for biological solids disposal depends, besides the technical feasibility, on the public acceptance of the product and on the availability of the market. This paper ...

Abstract: This study examines the rates of solids dislodgment of three synthetic solids with varying degrees of adhesive characteristics, for which a parameter characterizing the ease of solids breakoff from the surface of filter ...

Abstract: This paper proposes a filter performance prediction model that takes into consideration influent suspension characteristics. Two new equations are proposed. One relates the filter coefficient to the unit volume pore space ...

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 ...
