Submit Manuscript | http://medcraveonline.com Reverse osmosis (RO) membranes are commonly used for sea water desalination to produce fresh water. These membranes are usually prepared using interfacial polymerization. Hydrophobic diamine and water-soluble chloride salt precursor are reacted to form a thin polyamide (PA) separation layer on a porous support [1]. The PA cross-linking density has a...

Comparative seawater RO pretreatment evaluation using benchand pilot-scale testing Desalination using seawater reverse osmosis (SWRO) technology is an important option available to water-scarce coastal regions. Recent full-scale experiences have shown that pretreatment is the key for this application of RO technology. In this article, a unique series of benchand pilot-scale tests are presented....

At low pressure and temperature, water is easily vaporized under partial vacuum pressure. Desalination of seawater as source of potable water is globally considered as an applied reliable technology. At low temperature and pressure, the heat transfer process yield is higher than any normal process. Therefore, the rate of vaporization of seawater is much higher than any usual processes. The part...

The aim of this research is to study the effect high concentrations salts, pressure and temperature on performance RO membrane with time. Four different (Na2CO3) (5000, 15000, 25000 35000) ppm various pressures such as (1, 3 5) bars at temperatures feed solution (i.e., 25, 35 45) ◦C were used in work. It was found that, concentration salt increase, rejection decrease. While membranes increases ...

Isolated soy-protein products are useful for food ingredients because they provide solubility, water binding, fat adsorption, emulsification, viscosity, gelation, foaming, adhesion and cohesion, texturization, and flavor formation. Soy-protein concentrates (SPCs) and soy (SPIs) are the representative soy Conventionally, SPCs and SPIs have been produced by removing non-protein portions such as o...

In this work, we use a modified thin film composite RO membrane to examine the impacts of selectivity and compaction on performance pressure retarded osmosis. membranes are promising platforms study PRO because they tolerant typical pressures well characterized for permeance selectivity. Their availability across range (from nanofiltration seawater RO) also allows us systematically investigate ...

An optimal control of Reverse Osmosis (RO) plant is studied in this paper utilizing the auto tuning concept in conjunction with PID controller. A control scheme composing an auto tuning stochastic technique based on an improved Genetic Algorithm (GA) is proposed. For better evaluation of the process in GA, objective function defined newly in sense of root mean square error has been used. Also i...
