Seawater desalination

• Dense ZIF membranes are prepared through bio-inspired polydopamine modification. • ZIF membranes are developed for the first time for seawater desalination. • The ZIF membranes show high water flux and ion rejection for seawater desalination. In conclusion, in the present work we have successfully de

• Direct UF–RO integration was implemented through an advanced control scheme. • RO concentrate stream was utilized for UF backwash. • Pulse backwash significantly improved overall UF backwash effectiveness. • Self-adaptive UF backwash successfully retarded the progression of UF fouling. A novel RO d

• This is a first assessment in desalination application with a potential ecological indicator. • Ecological indicator studies of desalination project are reviewed. • Sustainability management of ecological indicators' major characteristics is important in risk and/or impact assessment. • This study

The energy, water and environment nexus is a crucial factor when considering the future development of desalination plants or industry in the water-stressed economies. New generation of desalination processes or plants has to meet the stringent environment discharge requirements and yet the industry

This study proposes an optimal study of reverse osmosis (RO) seawater desalination system based on the split partial second pass (SPSP) design in order to fully utilize better quality and higher flux for the permeate at the front of the pressure vessel (PV). Differential equations in the membrane tra

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

A technique to optimise thermal efficiency using brine recycling during direct contact membrane distillation (DCMD) of seawater was investigated. By returning the hot brine to the feed tank, the system water recovery could be increased and the sensible heat of the hot brine was recovered to improve t

Saline water such as seawater or brackish water is a potential source for drinking water or for non-potable applications, but the existing desalination techniques are energy intensive. Therefore, there is an urgent need to develop sustainable desalination methods. Microbial desalination cells (MDCs)

In this paper, authors breakdown the specific energy consumption for seawater and brackish water desalination in an attempt to quantify the value of high permeability membranes on specific energy consumption for desalination. The trends from the analysis presented in this paper show that in both seawa

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
