Removal of Specific Pollutants during Greywater Recycle

Problem

Grey water treatment provides an avenue for novel techniques to be used to optimize and improve treatment processes that reduce the pressure put on the water cycle. Creating processes to convert grey water to potable water standard efficiently is crucial.

Solution

Greywater is fast becoming a dependable source of water for non-potable uses, reducing the stress placed on fresh water that could be used for potable applications. In parts of the world where water sources are receding increasingly, Greywater recycle and reuse is the most potent way to save water.

Although advanced decentralized systems provide solutions to improve the quality of greywater effluents, they do not meet water standards. My study will focus on the most pertinent issues that need to be solved to broaden the usability scope of greywater from toilet flushing to laundry, floor cleaning, irrigation, and car washing. To achieve this feat, the crucial parameters hindering this water matrix from meeting water standards have to be dealt with, and this is what my research will focus on.
