Life Cycle Assessment (LCA) Applied to the Design of an Innovative Drying Process for Sewage Sludge
Most adverse environmental impacts result from design decisions made long before manufacturing or usage. In order to prevent this situation, several authors have proposed the application of life
A Method for Determination of Porosity Change from Shrinkage Curves of Deformable Materials
Among the numerous models developed to predict the shrinkage of materials during drying, the model developed by Katekawa and Silva [1] gives a general relationship between shrinkage and porosity with
Comparison Between Static and Dynamic Methods for Sorption Isotherm Measurements
Abstract Sorption isotherms of Microcrystalline Cellulose (MCC), pharmaceutical granules, PolyEtherBlocAmide (PEBA) membrane and sewage sludges were measured at various temperatures using three
Preparation of Adsorbents from Sewage Sludge by Steam Activation for Industrial Emission Treatment
With an objective of production of carbonaceous sorbent for industrial effluent treatment, physical activation by steam of biological sludge collected from the municipal wastewater treatment plant of
Non-contact Measurement of the Shrinkage and Calculation of Porosity During the Drying of Banana
A novel non-intrusive technique (stereo-correlation) was used to determine the apparent volume of a banana in convective drying condition. The volume was calculated using the 3D Digital Image
Heat and Mass Transfer During Fry-Drying of Sewage Sludge
Deep-frying, which consists of immersing a wet material in a large volume of hot oil, presents a process easily adaptable to dry rather than cook materials. A suitable material for drying is sewage
Drying of Silica Gels to Obtain Aerogels:Phenomenology and Basic Techniques
Silica gels form a large family of materials, obtained from more or less complex processes; their elaboration involves several steps that basically include a sol gel transition or a precipitation,
