The main trouble in the RO method of seawater desalination is biological fouling (bio-fouling) from microorganism growth. In this work, the growth rate of microorganisms in the Red Sea and sterilization by chlorine injection were measured and quantified. Furthermore, actual demonstration of RO pilot

This paper presents the feasibility of the application of two commercial nanofiltration (NF) membranes (Desal5 DK and NF-270) in the removal of metal ions from an acidic leachate solution generated from a contaminated soil using H2SO4 as a soil washing agent. The experimental results of soil washing

The extraction and analysis of EPS in active biomass and membrane fouling were performed to investigate the influence of extracellular polymeric substances (EPS) on membrane fouling of MBR. The new membrane and fouling membrane surface morphology was characterized by EDX analysis. The results show t

An attempt has been made to evaluate inner and outer glass temperature and its effects on yield. Numerical computations have been performed for a typical day in the month of December, 2005, for the climatic condition of New Delhi (latitude: 28E35N N; longitude: 77E12N E and an altitude of 216 m abov

The batch removal of Fe3+ from aqueous model solution under different experimental conditions using Jordanian natural zeolite (JNZ) has been investigated. The influences of contact time, metal initial concentration, adsorbent dosage concentration, and temperature have been studied. The adsorption ef

The potentialities of castor seed shell (CSS), a waste agricultural by-product, in the remediation of water, contaminated with Methylene Blue (MB), a basic dye, were investigated in the present study. The CSS was ground and washed, thoroughly, to remove any water extractable constituents. The dried

This work aims to provide a detailed analysis of the heat transfer in direct contact membrane distillation (DCMD). The influence of mass transfer on heat transfer flux was identified in the feed thermal boundary layer, across the membrane and through the permeate thermal boundary layer. A mathematic

The performance of a series of membrane systems in separating a range of organic and inorganic solutes has been investigated. The performance of one such membrane XN45 (Trisep) was unexpected, and previously unreported effects were observed with respect to the dependence of the observed rejections o

Sludge from five full-scale flat-sheet submerged membrane bioreactors has been analysed with reference to the key biochemical fouling characteristics of soluble microbial product (SMP) and extracted extracellular polymeric substances (EPS). Correlations have been produced between these parameters, a

In this study, boron removal from aqueous solutions was examined using Dowex 2×8 anion exchange resin. The sorption behaviour of resin was investigated as a function of pH, contact-time and temperature, initial boron concentration of solution, resin dosage and effect of other ions. The maximum sorpt
