A protocol is proposed whereby waste fly ash and CO2 emissions from coal fired power plants are utilized in remediating brine waste. The solid residues generated may be used as mine backfill since they consist mainly of benign calcium carbonate. Following treatment with fly ash and CO2, over 99% removal

The present study evaluated the performance of pressure retarded osmosis–reverse osmosis (PRO–RO) process for power generation and seawater desalination. Two pre-developed software were used separately to estimate the performance of forward osmosis (FO) and RO process. The draw and feed solutions in

• We developed a portable solar-driven desalination system for producing potable water. • A stand-alone system which utilizes solar energy by combining PV/thermal collectors. • The system uses Vacuum-Multi Effect Membrane Distillation (V-MEMD) process. • We also reported some small-scale test result

In this paper, a performance evaluation of a multi-vacuum membrane distillation (VMD) module was conducted using a one-dimensional model. The mathematical model consisted of momentum, mass and energy balance equation using the water permeate flux model and heat flux model. The simulation results were

Integration of renewable energy with desalination technologies is a strongly emerging field in many regions of the world having drinking water and energy crisis. This study presents the results of a techno-economical investigation of a small scale, photovoltaic (PV) powered hybrid nanofiltration (NF)

This paper introduces a process synthesis strategy and optimization approach that accounts for boron removal considerations in Seawater Reverse Osmosis (SWRO) network design. The overall aim is to provide an improved understating of the performance of SWRO networks when specific requirements on boron

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

The worldwide demand for potable water has been steadily growing and is projected to accelerate while natural reserves of fresh water are generally flat or diminishing. Desalination of seawater or brackish groundwater is expected to make up the difference; however, the desalination of water is energy

The objectives of the present study were to test a new plasma-based method for bicarbonate removal in water produced from hydraulic fracturing for shale gas and to verify bicarbonate removal as a mechanism for mineral fouling prevention. The study employed dual hypotheses: (1) gliding arc plasma can

This study proposes a multi-objective optimization (MOO) of reverse osmosis (RO) networks for seawater desalination. The membrane transport model takes into consideration of the longitudinal variation of the velocity, the pressure, and the concentration in the membrane modules. The RO network with t
