Treatment and Effective Utilization of Greywater: A Preliminary Case Study

Greywater has been identified as a valuable alternative water source over recent years. Few practices (i.e., recycling and reuse) of greywater have attracted global attention in meeting the future demand. However, essential parameters should be analyzed for reliable reuse treatment. The present study addresses possibilities with treated greywater. Gravity—governed flow methods through column containing gravel, sand, activated carbon was applied. quality from university campus, which included physical, chemical, biological parameters, assessed to check non-potable suitability. reduction percentage organics oxygen demand chemical 64% 42%, respectively. Similarly, obtained at 74% 66% turbidity electrical conductivity. removal efficiency 57%, 77%, 48%, 44% total dissolved solids, alkalinity, chlorides, hardness. pH samples found neutral range suggesting its suitability reuse. Hence, proposed treatment method is cost-effective straightforward approach irrigation, watering lawns, car washing. collected can disinfected immediately reused minimal possibility regrowth microorganisms.
