This work proposes a mathematical dynamic model for the direct contact membrane distillation (DCMD) process. The model is based on a 2D Advection–Diffusion Equation (ADE), which describes the heat and mass transfer mechanisms that take place inside the DCMD module. The model studies the behavior of

Desalination via pervaporation has the potential to be an efficient way of getting fresh water from non-potable saline sources with the advantages of a high rejection of salt and the capability of coping with high-salinity solutions. This overview of desalination via pervaporation mainly focuses on m

We demonstrate the immobilization of graphene oxide on polytetrafluoroethylene (PTFE) membrane surface for desalination via direct contact membrane distillation. The graphene oxide immobilized membrane significantly enhanced the overall permeate flux with complete salt rejection, and the flux reached as

i n f o Generally speaking, it should be noted that CFD-based models are very qualitative. Actually, in practice the selection of the best case, i.e. the specific microstructure for membrane or spacer geometry and the module geometry includes a trade-off between the costs of membranes needed to produ

In this paper design and analysis of energy, exergy, economic and the environmental impacts (4E) of direct twostage reverse osmosis (RO) system have been optimized for supplying Miarkelar water, north of Iran using multiobjective optimization. In this city, water has been provided for a period of 20

Biofouling impacts seawater reverse osmosis (SWRO) desalination plants by hindering module performance, increasing energetic demands, and incurring further costs. Here we investigated the spatial–temporal dynamics of microbial communities along the feedwater, pretreatment, and reverse osmosis stages

This work presents a systematic evaluation of the membrane and process characteristics of a scaled-up pressure retarded osmosis (PRO). In order to meet pre-defined membrane economic viability (≥5 W/m2), different operating conditions and design parameters are studied with respect to the increase of t

In this study, a laboratory-scale membrane distillation (MD) system was developed for advanced treatment of biologically treated coking wastewater (BTCW), while the effect of pre-coagulation was also investigated. Results showed that membrane distillation could effectively reject the salts (N99.1%)

• A simplified membrane distillation coefficient calculation method is validated. • A stepwise modeling approach is shown to accurately model large-scale DCMD membrane modules. • A new spacer modeling method accounts for woven spacers with complex geometries. • Distribution of water flux, temperature a
