Abstract Three pilot systems of a constructed wetland were assessed to advance the urban reuse greywater for household gardening in areas world representative Africa's Sahel (one unplanted and two planted with local species, namely Andropogon gayanus Chrysopogon zizanioides). Principal component analysis showed provided higher removal efficiencies than system A. performed better treating most w...

The treatment of greywater (GW, wastewater share excluding toilet flush) through green walls can be beneficial for urban areas, favouring the diffusion vegetation and reducing potable water consumption. Multiple challenges hinder performance walls, including composition filtering material, number levels—i.e., rows—and age system. This study investigated graphene as an additive (5%v) to a medium...

The reuse of treated greywater in a residential setting could contribute substantially to easing problems with water scarcity. This paper argues that preferences relation reusing for different uses within the home vary across households and can be driven at least part by psychological constructs, such as attitudes perceptions, which might appear irrational face value from an economic perspectiv...

The reuse of household greywater is increasing globally. Wastewater and treatment processes are not fully effective in removing all contaminants, such as emerging micropollutants, antimicrobial-resistant bacteria, antibiotic resistance genes. dynamics between micropollutants genes systems complex. Thus, this review aims to analyze the current knowledge on sources, spread, fate antibiotic-resist...

In the effort to de-carbonize building stock, heat pumps are increasingly utilized in Switzerland, with 70% of fast-growing pump market using ambient air as source. Inexpensive and easy implement, these are, however, less efficient than their ground- or water-source counterparts. this modeling study, we aim at increasing efficiency air-source domestic greywater-contained heat. We assess perform...

Interest in greywater reuse is increasing South Africa, because of the potential to supplement scarce freshwater resources face demand and aridity. This paper aims inform water saving–risk trade-off associated with residential untreated use, through a statistical analysis quality results as sourced from prior African studies. Greywater sources included this review were bathroom, kitchen, laundr...

Abstract Potable water scarcity is a global issue. Recent and ongoing droughts in the Western United States make residential conservation crucial. Several agencies have invested programs that educate residents on non-traditional sources, such as laundry-to-landscape (L2L) greywater systems, which reuse washing machine for outdoor irrigation. This study analyzed landscape vegetation 21 character...
