AbstractThe 2018 edition of the United Nations World Water Development Report
stated that nearly 6 billion peoples will suffer from clean water scarcity by
2050. This is the result of increasing demand for water, reduction of water
resources, and increasing pollution of water, driven by dramatic population and
economic growth. It is suggested that this number may be an underestimation, and
scarcit... hiện toàn bộ

AbstractHigh molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly
used as a flocculant in water and wastewater treatment, as a soil conditioner,
and as a viscosity modifier and friction reducer in both enhanced oil recovery
and high volume hydraulic fracturing. These applications of PAM can result in
significant environmental challenges, both in water management and in
contamination ... hiện toàn bộ

AbstractPepper mild mottle virus (PMMoV) was recently found to be the most
abundant RNA virus in human feces, and is a plant virus belonging to the genus
Tobamovirus in the family Virgoviridae. When in human feces, it is of dietary
origin from peppers and their processed products, and is excreted from a large
proportion of healthy human populations, but rarely found in animal feces. Over
the past ... hiện toàn bộ
AbstractFor communities in developing countries, the majority of drinking
water-related issues are due to pathogens from poor sanitation, resulting in
infection and diarrhea. One cause of this is that these communities often do not
have access to centralized water treatment facilities. Point-of-use (POU)
systems are key solutions for treating water in developing communities; they are
typically use... hiện toàn bộ

AbstractThe chemical regeneration process has been extensively applied to
reactivate biochar, supporting its reusability and leading to significant
operating cost reduction. However, no recent review discusses the effectiveness
of biochar chemical regeneration. Thus, this article comprehensively reviews the
chemical regeneration of biochar contaminated with organic and inorganic
pollutants. Perfor... hiện toàn bộ

AbstractIon exchange (IEX) processes are a promising alternative to remove and
recover nutrients from municipal wastewater. To assess the feasibility and
viability of IEX processes for full-scale application, this study aimed at
providing an evaluation of performance and economics on upscaling these
processes for two different configurations in a 10,000 population equivalent

AbstractIn this study, an electrohydrodynamic atomization or electrospraying
technique is used for the uniform deposition of carbon nanotubes (CNT) on a
commercially available PTFE membrane and employed for Membrane Distillation (MD)
process. Modified PTFE-CNT membrane was characterized for water contact angle,
liquid entry pressure (LEP), pore size distribution, and surface morphology. The
electr... hiện toàn bộ

AbstractHeavy metals (HMs) are highly toxic water pollutants abundant in
industrial wastewater. Herein, a bis[3-(trimethoxysilyl)propyl]amine (BTMSPA)
cross-linked multiwalled carbon nanotube (MWCNT) nanomaterial (CQACNT) was
synthesized by silanization of MWCNT-OH followed by grafting of positively
charged quaternary ammonium groups (glycidyl trimethyl ammonium chloride
(GTMAC)) by an epoxide rin... hiện toàn bộ
