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: Coal bed methane (CBM) is naturally occurring methane, contained in coal seams saturated with water. In order to extract the CBM, large quantities of water must be pumped from the coal seams. CBM water, produced in some ...

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: An analytical model for predicting the strengths of exterior reinforced concrete wide beam-column joints is developed in this paper. In the proposed model, the shear strength of the joint core is derived based on the ...

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 ...
