Removal of Trihalomethanes by Dual Filtering Media (GAC-Sand) at El-Manshia Water Purification Plant.
Prechlorination is used as an initial step in water purification for public supply. One of the drawbacks of the prechlorination is the reaction between natural organic matters with chlorine forming trihalmethanes. This study aims at evaluating the performance of granular activated carbon (GAC) with sand as a dual filtering media with different depths on removal of trihalomethanes (THMs) for imp...
متن کاملExperimental design and response surface modeling for optimization of humic substances removal by activated carbon: A kinetic and isotherm study
The presence of humic acid (HA) in water treatment processes is very harmful and the cause of undesirable color, taste, and smell. Drinking water containing high concentrations of humic substances can be the cause of many health problems. Therefore, the removal of these compounds from water resources is a very important topic. In this research, response surface methodology (RSM) has been used t...
متن کاملModeling and Optimization of Arsenic (III) Removal from Aqueous Solutions by GFO Using Response Surface Methodology
Arsenic is a highly toxic element for human beings, which is generally found in groundwater. Dissolved Arsenic in water can be seen as As+3 and As+5 states. The adsorption process is one of the available methods to remove Arsenic from aqueous solutions. Thus, this papers aims at removing Arsenic (III) from aqueous solutions through adsorption on iron oxide granules. The relation among four inde...

متن کاملThe efficiency of modified powdered activated carbon for removal of ammonia nitrogen from aqueous solution: a process optimization using RSM (Response Surface Methodology), adsorption isotherm and kinetic study
The objective of this study was to determine the performance of modified commercial powdered activated carbon (MCPAC) in removal of ammonia from aqueous solution. The effects of adsorbent dosage (0.5–1.5 g/L), ammonia concentration (100–200 mg/L), pH (3 to 9) and contact time (2 to 120 min) were examined. In this study, experiments were performed based on Response Surface Methodology (RSM). The...
