Conversion of grey water to potable water using LDH-Biochar composite

The worldwide freshwater shortage is worsened by the excessive use and contamination of scarce resources. A considerable amount of domestic wastewater is greywater, originating from activities such as bathing and laundry, and can account for as much as 70% of household water discharge. In contrast to black water, greywater contains fewer organic materials and nutrients, making it an ideal candidate for recycling. This research explores a new approach to transform greywater into drinking water using a composite made of Layered Double Hydroxide (LDH) and Biochar. This composite is designed to utilize the combined adsorption abilities of LDH along with the high surface area and filtering properties of Biochar to effectively eliminate pollutants. The study assesses how well this composite purifies greywater to adhere to drinking water regulations, offering a sustainable and creative solution to mitigate water scarcity by allowing safe water reuse.
