Biography
Kailas Malwade is, a lecturer and researcher, working at the University of Aruba, in collaboration with KU Leuven within the SISSTEM program. He is an environmental engineer with professional experience of eight years with government agencies in India and the US. He earned his Ph.D. in Environmental Engineering from Texas A&M University Kingsville in August 2017. His current research is focused on the numerical modeling of a solar food dryer and thermal energy storage system. In the past, he worked in the field of air and wastewater pollution and researched the aqueous-phase and gas-phase adsorption of single and multicomponent contaminants using carbon-based adsorbents.

    Application of carbon nanotubes for removal of emerging contaminants of concern in engineered water and wastewater treatment systems
    (Springer Nature, 19-Apr) Kurwadkar, Sudarshan; Hoang, Timothy V.; Malwade, Kailas; Kanel, Sushil R.; Struckhoff, Garrett; Malwade, Kailas
    Pharmaceuticals and personal care products (PPCPs) and endocrine disrupting compounds (EDCs) have been detected in wastewater effluents and surface water bodies at concentrations ranging from parts per trillion levels (ng L−1) to parts per billion (µg L−1) levels. Currently, engineered wastewater treatment plants are unable to remove PPCPs and EDCs completely, resulting in the treatment plants becoming a source of secondary pollution. Research on carbon nanotubes (CNTs) has shown that the tubular cylinders of carbon atoms due to their large specific surface area and developed pore structure are capable of adsorbing and remediating PPCPs and EDCs. They also possess excellent photocatalytic activity and high mechanical strength. When combined with membrane filtration, CNTs demonstrate excellent removal of PPCPs and EDCs with removal up to ~ 95% in optimum experimental conditions. Nanocomposite membranes containing CNTs have shown promising results in the removal of triclosan, acetaminophen, and ibuprofen. In addition to its proven potential in adsorption and membrane filtration, CNTs can also be used in photocatalytic degradation of a variety of organic compounds including PPCPs and EDCs. When CNT is used as a photocatalyst, it generates reactive oxygen species that can oxidize contaminants to CO2, and H2O. This study provides a comprehensive literature review of the application of CNTs for removal of the emerging contaminant of concern from water and wastewater. Their application, particularly in the areas of adsorption, filtration and photocatalytic degradation of PPCPs and EDCs, is discussed in detail. Also, the feasibility of a full-scale implementation of CNTs in existing water and wastewater treatment plants is discussed.
