“…In the context of adsorbing contaminant species however, CNTs exhibit a high available surface area due to their nanoscale, as well as a high proportion of accessible micropores in their aggregated form [109]. There is also a large degree of scope for fabricating composite materials of CNTs, including embedded polymers, nanoparticle grafted CNTs and electrospun fibers [110][111][112]. The two main forms of CNTs, namely single walled carbon nanotubes (SWCNTs) and multi walled carbon nanotubes (MWCNTs), also allow further flexibility when designing water filtration and purification materials.…”

Abstract:To ensure the availability of clean water for humans into the future, efficient and cost-effective water purification technology will be required. The rapidly decreasing quality of water and the growing global demand for this scarce resource has driven the pursuit of high-performance purification materials, particularly for application as point-of-use devices. This review will introduce the main types of natural and artificial contaminants that are present in water and the challenges associated with their effective removal. The efficiency and performance of recently developed materials for water purification, with a focus on activated carbon, carbon nanotubes and graphene will be discussed. The recent advances in water purification using these materials is reviewed and their applicability as point-of-use water purification systems discussed.

“…A modern maturation in water treatment is the introduction of membrane filtration to potable water treatment (Rojas et al, 2008;Lin et al, 2006;Williams et al, 2012). Membrane filters have been revised to the level where, in some situations, they are appropriate as stand-alone remediation for small set-ups (Singh et al, 2010;Patsios et al, 2013;Oh et al, 2007;Doederer et al, 2014). To a greater extent, they are utilized in coupling with other treatment techniques to economically enhance the global quality of finalized potable water (Rachwal and Judd, 2006;Guo et al, 2016).…”

Membrane filtration is a physical separation process and eliminates undesirable matters from water without employing chemical products that may conduct to unwanted secondary products (Patsios et al, 2013;Shetty et al, 2003;Rana et al, 2014Rana et al, , 2012Narbaitz et al, 2013;Bolong et al, 2010).…”

The generation, monitoring, and health impacts of disinfection by-products (DBPs) in potable water are problems of worldwide worry. Several nations, besides the World Health Organization, possess regulations and/or guidelines on bearable levels of DBPs in water. Since drinking water is frequently remediated using a chemical killing agent, DBPs are pollutants to which several humans are unprotected. On account of the health impacts linked to subjection to chlorinated water and/or some DBPs, the water manufacturing has performed great endeavors to equilibrate killing pathogens and DBP monitoring. Large survey has been realized on rising DBPs of health and regulatory worry. In spite of the fact that the attention on DBPs was previously on chlorine-and bromine-containing carbonaceous DBPs, appearing DBPs comprise iodine-containing species, also halogenated and non-halogenated nitrogenous DBPs. In addition, latest toxicity experimentation has proposed that certain of the more recent PBPs are of more elevated toxicity than some of the regulated chemical products. Therefore, survey has been realized to better comprehend how to costeffectively monitor a large interval of regulated and appearing DBPs. This comprises the usage of advanced remediation and killing pathogens methodologies. This paper shows certain of the newest research works at comprehending these significant DBP-related problems. Disinfection is killing microorganisms present in water; but, it is as well killing human beings drinking water by poisonous DBPs. Using chemicals for water treatment is finally a lost cause.

Here, for the first time, oxygenated amorphous carbon/graphite (a‐COx/G) hybrid nanofilaments are produced and used as the building blocks of a buckypaper membrane. The nanofilaments are in fact the innovatively chopped version of brittle, highly graphitized polyacrylonitrile precursor nanofibers. The high temperature (1250 °C) graphitization and then fast cooling bring about biphasic nanofibers made of graphite and amorphous carbon, readily reoxidized during cooling. The combination of polar and nonpolar domains in the nanofilaments governs a desirable amphiphilicity, thus selectivity to a variety of polar/nonpolar water pollutants. Through electrostatic and π–π interactions, the membrane efficiently discriminates amphiphilic castor oil as well as cationic methylene blue dye from water. Moreover, the buckypaper‐like structure of the membrane is 100% efficient in depth filtration of colloidal particles from water. The membrane's water flux is 16 times higher than that of commercial microfiltration membranes, promising an advanced energy/cost efficient filtration process. Thus, being multispectrally selective and highly water permeable, the a‐COx/G nanofilamentous membrane is regarded potentially a next‐generation, cost‐effective, and sustainable alternative to the long‐existing thin‐film composite membranes for water treatment.
