As a biomass material, cotton was investigated for feasibility to be used as a cost-effective biosorbent for boron removal as the post-treatment in a desalination plant. Based on the batch tests, cotton demonstrated a good capacity of adsorption at a pH about 7. This capacity was found to increase w

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

This is Part 2 of the paper “Performance analysis of combined humidified gas turbine power generation and multieffect thermal vapor compression desalination systems — Part 1: The desalination unit and its combination with a steam-injected gas turbine power system”. A combined power and water system

Desalination is an energy intensive process. All seawater desalting processes, multi-stage flash (MSF), multieffect boiling (MEB), and seawater reverse osmosis (SWRO) consume significant amounts of energy. In view of the rising fuel costs, US$75 per barrel of oil, the amount and cost of fuel consume

Electrical impedance spectroscopy was used for the characterization of electroregeneration in a continuous electrodeionization (CEDI) system packed with cation-exchange resin (CIX). CEDI process usually operates in two regimes of enhanced transfer and electroregeneration. The current efficiency decr

Major municipal wastewater reclamation plants in California, USA, Singapore, and many built or planned for other regions of the world use the high pathogen reduction properties of microfiltration/ultrafiltration (MF/UF) membranes followed by reverse osmosis (RO) membranes. Operational experiences in

High strength industrial wastewater was treated using a pilot scale submerged membrane bioreactor (MBR). The MBR was maintained at higher sludge concentration of 14,500 mg/l at prolonged sludge retention time (SRT). It was found that the prolonged SRT MBR could achieve both COD and TOC overall remov

MSF desalination plants occasionally experience interruption of antiscalant dosing or circulation of cleaning balls. The interruption may be either due to sudden system failure or the system is to be isolated for maintenance works. In such situations, specific operational procedures are normally ado

Development of systems with reduced emission of pollutants is one of the major challenges of this century. Fuel cells promise to provide clean and renewable source of energy, which can operate on many fuels. They are promising candidates for transportation and portable power source applications. The

A distribution function to predict the hourly global solar irradiance is suggested fitting with published experimental meteorological data in Jeddah, Saudi Arabia, and Hong Kong in China. The predicted formula is used as a source function together with heat diffusion equation and heat balance equati
