In brackish water RO desalination, the low feed water TDS and relatively low brine flow make the use of energy recovery devices ambiguous. The decision to implement energy recovery device must always be based on the Life Cycle Cost estimation of the plant. Design considerations concerning the energy

Solar still desalination systems offer sustainable tools for fresh water production. However, their widespread application is often hindered by their relatively low production rates compared to other desalination methods. In this study, a simple amendment, in the form of a slowly-rotating hollow cyl

Hypersaline solution with high TDS is not suitable for direct treatment by the conventional membrane and thermal processes. The current study proposes a dual-stage FO/PRO process for hypersaline solution treatment and power generation. The treatment process reduces the concentration of saline wastew

An energy-efficient design strategy for networking membrane modules and heat exchangers in membrane distillation (MD) process was developed in this work. A numerical simulation model was used to describe heat and mass transfer in direct contact type MD membrane module. Mass transfer coefficients were

This study presents the retrofit of water supply chain problem through multi period mixed integer linear program (MILP) model. The major strategic decisions include the determination of optimal new facility locations and capacity expansions of water desalination supply chain infrastructure assets whi

The desalination industry has been growing progressively in the last few decades. A large number of new plants are contracted every year. Strategic decisions related to plant locations and capacity, the selection of the desalination technology, and many other technical decisions related to the plant

i n f o Two reactors were operated for 20 desalination cycles (one desalination cycle contained 10 batch-fed operational cycles) with an initial Cr6+ concentration of 100 mg/L and pH values of 2.0 and 3.0, respectively. Curves of current density and cathode resistance are shown in Fig. 7 (A–B). As s

i n f o An FMDC can be an efficient method for desalination of brackish water with the additional function of copper(II) removal. The synthetic wastewater containing copper(II) in the cathode could accept electrons produced by a biofilm in the anode chamber, and the copper(II) was reduced to Cu2O/Cu.

Emphasizing upon the need to develop and target applications of low cost ceramic membranes, this work addresses the cross flow microfiltration (MF) of oil–water emulsions. Membranes prepared using uniaxial dry compaction method and possessing higher average pore sizes (3.06–2.16 μm) and porosities (30

• A simple model describing countercurrent single-pass electrodialysis is established. • Concentration distribution along the membrane is calculated. • Influence of concentration distribution on scaling risk is discussed. A simple model based on division of electrodialyzer into the elementary units a
