Abstract:

Wastewater treatment technology has been improved and modified to get higher removal efficiency and to meet the stringent effluent regulations. However, from a worldwide perspective, wastewater treatment process is facing many challenges, especially nutrients removal, thereby resulting in the serious concern for enhancement and modification of the existing wastewater treatment processes to achieve better removal efficiency. Nutrient and organic removal from wastewater is becoming an important priority for wastewater treatment plants due to the detrimental impact of these components on the receiving bodies. Therefore my research study aims to evaluate a moving bed biofilm reactor (MBBR) system for effective nutrient and organic removal from municipal wastewater which has promising prospects in terms of achieving high nutrient removal efficiency by reducing the operating cost. This study puts forward a systematic study on the effect of polyethylene (PE) carriers filling rates, the influence of aeration rate and different hydraulic retention time (HRT) on the organic and nutrient removal from municipal wastewater using continuously operated MBBR system in order to determine the optimum operating condition. To further verify the feasibility of MBBR system operated at optimum condition, this system was combined with a membrane filtration system to investigate the performance of the combined system in terms of organic and nutrient removal efficiency. My research activities during my research period were mainly focused on literature review in this field and lab scale investigations. This report compiles introduction of the study, literature review, materials and methodologies used, all the specific experimental results, findings and conclusion drawn from the whole study period.
