Abstract: Conventional methods used for drinking and waste water treatment and purification require reevaluation and enhancement in order to improve deteriorating water quality and water issues being faced around the globe. Nanotechnology including Carbon nanotubes (CNTs) are emerging technologies that offers operational and economically feasible solutions for treatment of drinking and wastewater. This brief review covers various CNT applications for drinking and wastewater treatment. CNT filters and POU based CNT water treatment can serve as high quality adsorbents for removal of biological as well as heavy metal contaminants commonly found in water treatment plants. On the other side promising applications of CNTs for waste water treatment include membrane processes, disinfection and microbial control, detection of water borne pathogens and monitoring and sensing of wastewater. CNTs are achieving tremendous attention worldwide in water/ waste water treatment and has potential for future implications.
