This study aims at studying the environmental effects of desalination byproducts and the cost analysis of desalination systems. Focus was made on the two widespread techniques of seawater desalination; the Multistage Flash (MSF) System and Reverse Osmosis (RO) system. These two technologies of thermal and membrane desalination have a substantial history and their industry is well established. M...

Energy recovery devices in Seawater Reverse Osmosis Systems (SWRO) reduce energy consumption and may facilitate the large-scale deployment of desalination systems. In this paper, a Rotary Vane Recovery Device (RVERD) is analysed optimised by aiming at weakening cavitation improving volumetric performance machine. An innovative analytical methodology based on user defined nodal displacement prop...

The origin and continuation of mankind is based on water. Water is one of the most abundant resources on earth, covering three-fourths of the planet’s surface. However, about 97% of the earth’s water is salt water in the oceans, and a tiny 3% is fresh water. This small percentage of the earth’s water—which supplies most of human and animal needs—exists in ground water, lakes and rivers. The onl...

Abstract Microcoagulation has recently been considered as a promising pretreatment for an ultrafiltration (UF) process from numerous studies. To investigate the effects of microcoagulation on performance UF–reverse osmosis (RO) system treating wastewater with high and fluctuant salinity, different dosages coagulant (poly-aluminum chloride) were added prior to UF unit in pilot-scale UF–RO 10-wee...

A two-step protocol (nano-filtration and reverse osmosis) was applied for natural organic matter (NOM) preconcentration of a seawater sample. Complexing affinities of the so concentrated marine dissolved NOM (DNOM) towards major and trace cations were studied by potentiometric and voltammetric titration techniques. The potentiometric titration experiments fitted by models describing and charact...

A finite element based numerical model has been employed to describe momentum and mass transfer in open and spacer-filled crossflow membrane channels. Simulations considering operating conditions typical of seawater (SW), brackish water (BW), and reuse water (RW) reverse osmosis (RO) applications are employed for optimization of hypothetical spiral wound element feed spacer designs. Preliminary...
