• Simulation and sensitivity analysis of integrated SWRO-PRO system configurations for eliminating brine post-treatment step. • Identification of energy efficient novel SWRO - PRO hybrid desalination process for reducing the SWRO pre-treatment cost. • Method for optimization of hybrid SWRO-PRO system d

This paper presents a novel mathematical formulation for modeling-based optimization of the multiple effect distillation (MED) water desalination process using thermal vapor compression (TVC). The presented model is based on a mass flowrate decoupling concept where flowrates of salt and water in the p

In this work, a simple and cost-effective pretreatment upstream an UF membrane operation for the purification of the main olive mill effluent streams (OME) is examined. The raw wastewater was processed by a pH-temperature (T) flocculation process formerly studied at lab scale in previous work. In the p

Forward osmosis (FO) has recently attracted growing attention in wastewater, brackish groundwater and seawater desalination, and power generation. This study evaluates the potential of using a batch laboratory-scale FO system as a pre-treatment for the reverse osmosis (RO) process. FO is a low press

Increasing demand for water in urban areas and agricultural zones in arid and semi-arid coastal regions has urged planners and regulators to look for alternative renewable water sources. Seawater reverse osmosis desalination plants have become an essential supply source for the production of freshwa

As a means of optimizing desalination processes, site-specificity in the determination of seawater quality conditions is a crucial point for improving the overall energy efficiency of a seawater reverse osmosis (SWRO) process. To this end, field studies were carried out at 16 sampling sites along th

In a previous paper, the performance of the humidification–dehumidification (HD) desalination process was optimized through mathematical programming. In this paper, by adding a solar system to the model, the total solar HD system is optimized. The main purpose of this optimization is the reduction o

In this paper the humidification–dehumidification desalination process is studied and its performance optimized using mathematical programming. An advantage of this method is consideration of the simultaneous effect of various parameters on process performance. An NLP system model is solved for thre

The present work summarizes the MED–TVC (multi effect desalination with thermal vapor compression) technique associated with the state of the art of modern desalination. In addition, a computer simulation model for all types of evaporation processes is presented. This program provides engineers with

This study proposes a new operation methodology for energy saving in the Fujairah seawater reverse osmosis (SWRO) plant, as the optimum feed pressure is determined at the controlled operating temperature. To this end, two functional models were developed by genetic programming (GP) using two-year op
