Review of seawater natural organic matter fouling and reverse osmosis transport modeling for seawater reverse osmosis desalination, Desalination and Water Treatment, 15:1-3, 92-107To link to this article: http://dx. ab s t r ac tTo date, over 80 papers on transport modeling and natural organic matter (NOM) relating to seawater reverse osmosis (SWRO), have been reviewed. As a result of such focus, NOM, one of the main foulants related to reverse osmosis (RO) membranes, has been shown to possess intrinsic chemical complexities and ambiguities, necessitating further investigation. Consequently, since such NOM fouling and transport mechanisms associated with SWRO are not fully understood, a summation of previous studies has been included in the paper in question to systematize information, not only as to RO membrane transport modeling, but NOM fouling characteristics, as well. Accordingly, RO transport models in the review are classified into three categories: diffusion-based, pore, and irreversible thermodynamic models. In addition, specific features, unique assumptions, and applications for each model are examined. The paper consists of the following components towards meaningful understanding of NOM fouling model development during SWRO: 1) SWRO fundamentals as to membranes, 2) NOM fundamentals as to seawater, 3) RO transport modeling theories, 4) conclusion, and 5) future directions of NOM fouling model development.

“…Recently, seawater reverse osmosis (SWRO) desalination processes have been widely adapted in the worldwide, because it is more economically feasible than distillation desalination processes such as multi-stage flash (MSF) and multi-effect distillation (MED) [2]. Furthermore, since a number of researches related to energy saving and cost reduction in SWRO desalination process have been carried out, it is expected that the production cost of fresh water can be continually reduced, leading to more expansion of the SWRO desalination process for fresh water production from seawater [3][4][5][6][7][8].…”

Large energy consumption is one of the main weaknesses of RO desalination. A new method is proposed to reduce the energy consumption of RO desalination which depends on the salinity of the feedwater. Low salinity feedwater can be obtained using groundwater wells which extracts both fresh groundwater and subsurface sea water. Subsurface feedwater is advantageous in overcoming other problems associated with surface seawater intakes. Salinities of groundwater depend on a number of factors. In this work a new simulation-optimization model is proposed to identify well locations and pumping rates with would provide the required design flow rate with the minimum salinity. When groundwater is developed in a coastal area, the saltwater wedge advances inland and may contaminate existing groundwater wells, which must be prevented. The model can protect existing wells while developing minimum salinity feedwater. Examples are provided to demonstrate the usage of the model.
