Moving Bed Biofilm Reactor (MBBR) for Decentralized Grey Water Treatment: Technical, Ecological and Cost Efficiency Comparison for Domestic Applications

The reuse of greywater has several advantages, including reduced freshwater extraction from rivers, aquifers, and groundwater; need for desalination; less environmental impact septic tanks water treatment plants; decreased energy consumption; chemical pollution. main objectives this review study are to assess the technical attributes, ecological impacts, cost-efficiency Moving Bed Biofilm Reactor (MBBR) technology compared similar available small medium-sized, decentralized applications in residential commercial settings such as home gardening, sanitation, landfills. Previous studies indicate that hybrid technologies MBBR most promising methods total removal contaminants wastewater a setting. However, initial capital cost medium-scale domestic worldwide is high so limiting factor expansion its utilization. Expansion use Decentralized Wastewater Treatment Systems (DWTS) could increase economies scale therefore reduce costs useful treatment. For system, Chemical Oxygen Demand (COD) efficiency was found be 70%, Total Suspended Solids (TSS) 97%, turbidity 98%
