The main objectives of this review study are to assess the technical attributes, ecological impacts, and cost-efficiency <br>of Moving Bed Biofilm Reactor (MBBR) water treatment technology compared to similar available technology for small to medium-sized, <br>decentralized applications in residential and commercial settings such as home gardening, sanitation, and landfills. Previous studies <br>indicate that hybrid technologies such as MBBR are the most promising methods for the total removal of contaminants in wastewater in a <br>decentralized setting. However, the initial capital cost of this technology for small and medium-scale domestic applications worldwide is <br>high and so is a limiting factor in the expansion of its utilization. Expansion of domestic use of such Decentralized Wastewater Treatment <br>Systems (DWTS) could increase the economies of scale and therefore reduce the initial capital costs for this useful water treatment. For <br>the MBBR system, Chemical Oxygen Demand (COD) removal efficiency was found to be 70%, Total Suspended Solids (TSS) removal <br>was found to be 97%, and turbidity removal was 98%</p> ER -
