Moving bed biofilm reactor (MBBR) technology using an eco-friendly carrier has been introduced recently to industrial wastewater to address the difficulties faced by conventional carriers used for wastewater treatment processes. This research examined full-lab scale MBBR systems treating industrial wastewater generated at Paper Manufacturing Industries in Salem, Tamilnadu. The study focused on the carrier, attempting to reduce the secondary pollution footprint in the ecosystem. The experiment varied the carrier fill fraction to 40%, 50%, and 60%. The lab-scale Moving Bed Biofilm Reactor has dimensions of 30 x 30 x 30 cm, and the hydraulic retention time was kept at 15 days. Carrier performance was analyzed on the 7th, 10th, and 15th days with the help of biofilm generation. During operational intervention periods, radical changes were observed in total dissolved solids, biochemical oxygen demand, chemical oxygen demand, and chloride at 50% and 40% carrier fill fractions. The environmental impact potential scale was used to analyze the impact of disposal practices for biofilm-shaped carriers. A cost-benefit analysis was designed for using eco-friendly and conventional carriers by comparing design and functioning efficiency. This is the first report on the design and analysis of an eco-friendly carrier for treating industrial wastewater using the MBBR process, which should provide a basis for optimizing MBBR plants in the future.
