Assessment of physiochemical properties of grey water

Abstract

Greywater, a type of domestic wastewater, is a potential solution to global water shortages, which are expected to affect 2.7 billion people by 2025. Greywater is safer to handle and treat than black water, making it suitable for non-potable uses like toilet flushing and landscaping. It also promotes ecologically sustainable development by reducing freshwater extraction, energy use, and chemical pollution. The process of processing greywater involves considering factors like biological oxygen demand, surfactants, oil and grease, and detergent residues. This study was evaluated greywater’s physical and chemical parameters in accordance with Indian standards.
