Description

Most technological solutions are developed in isolation of the target population. Water treatment devices are no exception. It is well known that the simplest of water treatment solutions (e.g., chlorine distribution for disinfection) are often not effective to render the benefits that these are intended to deliver. This talk will highlight our recent efforts in developing socially embedded water treatment solutions for inactivation of microbes and removal of contaminants from water for low-income communities in the United States (i.e., those that are living in the U.S.-Mexico border region and in the Navajo Nation) and beyond. In our efforts, nanomaterials are incorporated in treatment devices to address water quality issues that are either challenging to address or are mostly neglected by the current environmental engineering and science research. We are aiming to adopt socially acceptable practices and/or materials as well as are taking advantage of already diffused devices (not necessarily used in water treatment) for development of such solutions. Nano-silver is impregnated into ceramic surfaces with a naturally collected resin for a disinfection application. Nano-silver and other nanomaterials are also utilized to harness microwave radiation for inactivation of Legionella pneumophila. Field surveys and water quality assessment have been conducted to identify the social drivers for water use. In addition to discussing the technical results on these projects, this talk will also highlight our efforts in device engineering for safely utilizing nanomaterials for water treatment.

Nano-enabled Water Treatment: Socially Embedded and Safe Routes of Application
