This study explored the effect of increasing nanofiltration (NF) permeate recovery (RNF) by recirculation and dosage of chemicals on NF separation performance, concentration polarization (CP) and accumulation of scalingprone ion concentration on NF membrane surface. The related coupling effect on sea

There has been an increasing interest in using exergy as a potential tool for analysis and performance evaluation of desalination processes where the optimal use of energy is considered an important issue. Unlike energy, exergy is consumed or destroyed due to irreversibilies in any real process and

An investigation was conducted to determine the feasibility of using reverse osmosis (RO) membranes to treat water containing up to 50% (by volume) oil. The effect of varying the feed pressure, pH and temperature on separation performance of two thin film composite polyamide RO membranes was evaluat

The aim of this study was to investigate the application of sequencing batch reactor (SBR) technology for treating grey water collected at outlet of showers room of students. The performance of SBR was satisfactory as the effluent had respectively 20 and 5 mg/L of COD and BOD. Applied two hydraulic

A comprehensive measurement programme was carried through 300 kW Nordtank stall-regulated horizontal axis wind turbine. These turbines were erected at the test station for windmills by Hurghada Wind Energy Technology Centre. To the extent necessary to understand the measurement carried out, all expe

An experimental investigation on the effect of blade surface roughness, due to dust accumulation, on the performance of wind turbines was performed. The development of the energy generating costs of wind turbines directly depends on the wind turbine output, which depends upon the characteristics of

The performance of the drying chamber of a solar assisted drying system was analyzed. The solar assisted drying system consists of drying chamber, V-groove collector of 13.8 mð area, the auxiliary heater and two variable speed centrifugal fans. K-type thermocouples were used for temperature measurem

In this work, an approach to study the long-term performance of an industrial water desalination plant is described. Operational data corresponding to the time period of 454 days were analysed and from the results obtained it was found that the normalized water permeability coefficient declined by a

RO plant operators, end-users, membrane manufacturers and system suppliers have been facing two major problems since the advent of commercial membrane technology applications for water desalination utilizing reverse osmosis (RO) and other membrane processes: how to reliably monitor their membrane sy

All of the Saudi large MSF plants operate within the context of dual-purpose facilities for the simultaneous production of power and water. Such co-generation arrangement uses either backpressure or extraction condensing turbine. Co-generation cycles which were used till 1982 were employing extracti
