Abstract
Thesis Title : Using Glauconite in Wastewater Tertiary Treatment : Summary : The presence of phosphate and RY160 dye in the water is a great challenge because of its many disadvantages such as the negative affect on the environment, which requires the need for appropriate technology to remove these pollutants and reduce their impact on the surrounding environment. There are many techniques and methods used to remove phosphate and RY160 dye from water, but there are many disadvantage that require additional treatment work, such as the wastes resulting from the removal process, which contain high concentrations of pollutants and need additional treatment before disposal to reduce or eliminate their negative impact on to environment and also the high cost of removal work due to the use of chemicals such as what is used in chemical methods, as well as the low removal efficiency because the removal work is affected by the quality of the water being treated, as evidenced by biological treatment. The process of removing pollutants such as phosphate and RY160 dye using adsorption is considered as a promising method due to its high removal efficiency of pollutants, simple operation, the low costs required for the treatment process, in addition to the fast removal of pollutants in a short time, but the biggest challenge is how to dispose of waste resulting from removal process and reduce the negative effect to the environment before disposal. But the main disadvantage of adsorption of phosphate and RY160 ye in many previous research is the use of manufactured adsorbent materials, which requires high costs to prepare and activation of these materials to allowing them to be suitable for use in the adsorption process of phosphate and RY160 dye. To improve the adsorption process of removing phosphate and RY160 dye using cheap, effective and available materials with increasing adsorption capacity, glauconite was used in its natural form and after modification due to its high surface area, the presence of many functional groups on the surface, and also the presence of many elements in the composition of glauconite especially the main presence of silica with high ratio. In this study, the performance of adsorption of phosphate and RY160 dye from wastewater was studied using natural clay glauconite as low cost adsorbent and ecofriendly material. To enhancement the removal efficiency and adsorption capacity, modifications methods for the natural glauconite samples were applied using thermal activation (TAG) and acid activation (AAG). characterization of glauconite samples was done to study the effect of modification methods on to glauconite structure and surface area to evaluate the modification effect on to the adsorption removal ratio and adsorption capacity. The effect of different operational parameters such as contact time, pH, initial pollutants concentration, glauconite dose, and temperature was study regarding the adsorption of phosphate and RY160 dye. The study showed that glauconite samples after adsorption of RY160 dye, can reuse many times after regeneration or desorption of RY160 dye. Also glauconite considered as a natural and low cost material for phosphate and RY160 dye removal. >Furthermore, Artificial neural networks (ANNs) model of RY160 dye removal using natural and modified glauconite was conducted and yielded a high coefficient of determination (R2 of 0.99).
