Access to clean water, the essence of life, faces an alarming scarcity that poses a critical threat to humanity. Urbanization's surge and population growth have exacerbated the strain on clean water availability, heightening the imperative for wastewater treatment and recycling. Innovative green wall systems, representing on-site technologies for greywater treatment and reuse, hold immense promise. These systems offer an array of benefits to the environment, encompassing cooling, noise reduction, aesthetic enhancement, and more, while concurrently serving as a dependable alternative water resource. Yet, a formidable challenge emerges in the need to ingeniously engineer green wall systems capable of efficiently removing an extensive array of pollutants, including pathogens, nutrients, microplastics, and emerging contaminants originating from household chemical use, such as dyes, detergents, and personal care products.
