Biological wastewater treatment plants (BWWTP) are widely used to treat effluents from chemical process industry. However, there exist refractory substances, such as phenolic compounds, which require previous treatments. Advanced oxidation processes (AOP) are thoroughly being studied as pre-treatmen

The world increasingly depends on desalting seawater or brackish water for producing suitable and sustainable supplies of potable water for local populations, tourism, agriculture and industry. The energy cost component of desalinating seawater has historically been a large factor (up to 70%) of the

A mathematical model is proposed as a contribution to the modelling of the concentration polarization phenomenon occurring during increasing transmembrane pressure in membrane processes. The developed model is based on the extended Nernst–Planck equation (to describe the transport in membrane pores)

In the ultrafiltration (UF) of disperse dye solutions using ceramic membrane, backflushing is necessary to minimize the formation of fouling by disperse dye, and to enhance the permeate flux. In this work, the effects of backflushing on the ultrafiltration performance and decolorization were investi

One of the main problems in adopting extensive treatment for wastewater purification in hot climate countries, when also the effluent reuse is aimed, is the high evapotranspiration rate. This factor can play a key role in reducing the water output, a desirable effect in some cases but completely adv

Umm Al Nar Power and Desalination Plant is one of the largest plants in Abu Dhabi Emirate, United Arab Emirates. The plant was built in the mid eighties and its capacity was increased in 2001. The present plant capacity after the extension is 1000 Mega Watt power and 165 Million Gallon water per day

Hydrologic impact assessment is necessary for a planned development area in designing detention storage for urban drainage systems to minimize the effect of urbanization. It also has strong implication on pollutant loads from urban areas. For such assessment, single or two hydrologic models can be p

Diatomite, an abundant inorganic material in Jordan, was treated with sulfuric acid and heat treated in order to improve its performance as an adsorbent. The acid treated diatomite (ATD) was used to adsorb methylene blue from aqueous solutions. The equilibrium data were fitted to different adsorptio

The work presented in this paper deals with the investigations on the effect of heavy metal ions, e.g., Cu and Ni, on the localized corrosion behavior of carbon steel and SS 316L under different experimental conditions. The important experimental conditions which include the nature of aqueous medium

The paper deals with a novel solar powered water desalination technique based on direct osmosis process. The separation is driven by natural osmosis, which does not require external pumping energy as in the reverse osmosis process. Therefore, the specific power consumption of the desalination proces
