Abstract
Many industrial activities generate a significant amount of heavy metal and other pollutants ions in water via their wastewater effluents, which negatively impact the environment, aquatic life, and human health. Social pressure for a safe environment has forced governments to legislate more stringent measures for wastewater treatment especially for non-biodegradable pollutants, such as heavy metals to avoid contamination of the water body (river, ocean and sea). According to this policy, the present work is concerned with (Cu2+, Fe2+ and SO4 2- ) removal from wastewater. Copper and Iron are found with a variable concentration in several industries such as metal finishing industry, printed circuit industry, and the wastewater of mining industry while sulfate could be found from textiles, dyes, fertilizers industrial wastewater. Several different methods for the removal of heavy metal ions and other pollutants from wastewater have been studied over past decades such as chemical precipitation, electrodeposition, membrane filtration, liquid-liquid extraction, ion exchange process, electrocoagulation…etc The ion exchange process was found to be the most suitable method for wastewater containing low to moderate amounts of heavy metal ions due to its high removal efficiency in addition to its reasonable cost. This present work is dedicated to figure out the rotation effect on the removal rate of (Cu2+, Fe2+ and SO4 2- ) ion and the effect of resin height inside the basket to the basket diameter ratio (l/d) on the (Cu2+, Fe2+ and SO4 2- ) ion removal rate using a new design perforated rotating cylinder with aspect ratio (l/d) packed with a cation exchange resin for (Cu2+, Fe2+) and with an anion exchange resin for (SO4 2- ). Knowing that all experiments were done for each of the tested ions (Cu2+, Fe2+ and SO4 2- ) with its corresponding used resin separately. Previous studies proved that using either fluidized bed (Agitation of resin freely in solution) reactor or fixed bed reactor have drawbacks, where mass transfer of fluidized bed is low because of low slip (relative) velocity between the resin particles and the solution while fixed bed shows high-pressure DROP which would increase the pumping power and the operating costs of the process. The obtained experimental data was treated mathematically using dimensionless groups, from which an overall mass transfer correlation was obtained for each ion removal system; also the effect of different parameters on the rate and percent of removal was iv tested. Both Langmuir and Freundlich isotherm models were tested for the experimental data to determine the best fit model. The experimental results revealed that both the percentage of removal and the rate of removal of (Cu2+, Fe2+ and SO4 2- ) decreases as their initial concentration in the solution increases, while it increases as the contact time, rotation speed and (l/d) increases. Both Langmuir‟s and Freundlich‟s adsorption isotherms were examined, it was found that Langmuir‟s adsorption isotherm gives a better fitting for the obtained data than Freundlich‟s. Reliability of the (TRILITE MC-10H) was tested by reusing the same amount of resin for several cycles after regeneration for the removal of (Cu2+) ion, the resin showed a great performance ability up to 5 consequent cycles or adsorption and desorption.
