1. Experimental Comparison of Two Modifications of Activated Sludge for Treatment of Furfural-Containing Wastewater
Volume 2, Issue 1 , Winter 2005, Pages 3-9

Abstract
   A case study is presented in which two modifications of activated sludge treatment of complex chemical wastewater are experimentally compared: a combination of common activated sludge with powdered activated carbon treatment (PACT), and bioaugmentation of activated sludge treatment (BAST). Industrial ...  Read More

2. The Effects of Operational Parameters on the Efficiency of a Mixer-Settler Extractor
Volume 2, Issue 1 , Winter 2005, Pages 10-23

Abstract
  The effects and influences of various operational parameters on the efficiency of mixer-settlers are thoroughly studied in this paper. One of the most important factors in designing a mixer-settler is to obtain an optimum operational extraction and overall efficiency. These two factors are dependent ...  Read More

3. A New Model for Prediction of Heat Eddy Diffusivity in Pipe Expansion Turbulent Flows
Volume 2, Issue 1 , Winter 2005, Pages 24-33

Abstract
  A new model to calculate heat eddy diffusivity in separating and reattaching flows based on modification of constant Prt is proposed. This modification is made using an empirical correlation between maximum Nusselt number and entrance Reynolds number. The model includes both the simplicity of Prt=0.9 ...  Read More

4. Investigation of CO2 and H2O Addition to Natural Gas for Production of Synthesis Gas
Volume 2, Issue 1 , Winter 2005, Pages 31-54

Abstract
  General modeling and optimization of syngas production via noncatalytic autothermal partial oxidation of methane are carried out using our developed scientific software which was based on the minimization of total Gibbs energy. In this work, a novel application of the direct search and Newton-Raphson ...  Read More

5. Dynamic Modeling of Granular Sludge in UASB Reactors
Volume 2, Issue 1 , Winter 2005, Pages 52-60

Abstract
  n this paper, a mathematical model has been derived to predict the granulation time of anaerobic sludge in UASB reactors. In the proposed model, some physical, chemical and biological parameters affecting the granulation phenomena have been considered. To validate the model, 12 pilot-scale experiments ...  Read More

7. Prediction of Vapor-Liquid Equilibria Using CEOS /GE Models
Volume 2, Issue 1 , Winter 2005, Pages 71-81

Abstract
  The present study investigates the use of different GE mixing rules in cubic equations of state for prediction of phase behavior of multicomponent hydrocarbon systems. To predict VLE data in multicomponent symmetric and asymmetric mixtures such as systems that contain light gases (nitrogen, carbon dioxide, ...  Read More
