Optimization

The performance of reed bed systems is usually presented following a long-term evaluation of case studies. However, short-term water content analyses may be useful to better understand the dynamics of the dewatering process and hence to rationally describe the system, with the ultimate aim of improv

The production of a biosurfactant by Pseudomonas fluorescens Migula 1895-DSMZ was studied. Cultures conditions involving variations in carbon and nitrogen sources and different C:N ratios were examined at constant temperature and pH, with the aim of increasing productivity in the process. Biosurfact

In this paper, a new formulation based on disjunctive programming to model the superstructure of alternative configurations for the synthesis, design and analysis of combined cycle power and desalination plant recently developed in Mussati et al. [Desalination, 182 (2005) 123–129] is presented. In t

The present work summarizes parametric optimization technique of multi effect desalination with thermal vapor compression (MED-TVC) process to increase gain output ratio (GOR) value. In order to increase GOR value, a simulation model of MED-TVC system is presented. This simulation can provide engine

To reduce energy consumption in the buildings and minimize negative environmental impacts, it is necessary to determine the operating condition that provides optimum system performance. Entropy or exergy analysis can be used as a reliable tool for analyzing energy consumption and environmental impac

Electric energy consumption in the arid Saharan regions is continuingly increasing due to increasing urbanization. Photovoltaic solar energy may be a suitable form of alternative electric energy production due to the abundance of solar energy in this region. In this paper we are presenting the gener

This study investigated the feasibility of the once-through (OT) MSF design for constructing large-capacity desalting plants rather than the conventional brine recycle (BR) MSF configuration. This was to explore the possibility of improving MSF process economics through the application of a simpler

This is the last paper in a series of three parts entitled “Optimal design of hybrid RO/MSF desalination plants”. This research is concerned with exploring the feasibility of hybridization of multi-stage flash (MSF) and reverse osmosis (RO) technologies in order to improve the performance characteri

This work presents a new method, called heuristic selection (HS), to process algebraic equation systems (AEs). These systems are part of all chemical processes models that respect the state space models form. For given AEs, the proposed method produces a set of decision variables, a set of subsystem

In this paper, we investigate the possibility of adopting the Once-Through (OT- MSF) design in place of the conventional brine recycle (BR-MSF) design for the future, large scale desalination plants. It was assumed here that efficient anti-scale chemicals would be available. Thus, a top brine temper
