Smart Adsorption Greywater System

Abstract

Water scarcity is a rising issue world-wide that has been accelerated by population increase, rapid urbanization, and unavailability of fresh water, and therefore wastewater reuse is a key factor for proper water management. Laundry wastewater constitutes a substantial proportion of household wastewaters and can be reused safely for other uses following proper treatment. This study focuses on the Smart Adsorption Greywater System that can treat and recycle laundry wastewater at a household treatment. It employs a filtration and adsorption process using natural and low-cost material such as cotton, gravel, sand, micro-filter paper, and natural adsorbents like activated charcoal, activated Mahogany powder for the removal of suspended solids, clarification, adsorption of color and odor, and removal of detergents and dissolved organics, reduction of TDS, Turbidity, Conductivity, and pH. A disinfection stage is also provided at the end for ensuring the suitability of the treated water for use as non-potable water for irrigation practices, flushing of toilets, and other cleaning purposes. The project proves the ability for a low-cost water recycling conservation technology.
