NFCDI – Nanomembranes for cost-effective hybrid desalination-filtration of wastewater

The work proposed herein, aims to provide an improved and efficient treatment of brackish water and wastewater using carbon nanomembrane (CNM) multilayers electrodes, answering the increasing regulations that governs the allowable levels of total dissolved solids (TDS) and suspended solid particles (SSP) in potable water, and to assess the potential reduction in initial capital investment as well as the estimation of operating costs of wastewater treatment.

Suggested herein an Innovative route for brackish and wastewater purification technology using of ultrathin (0.5 – 3nm), mechanically robust, large area (CNMs) with tailored pore size and the preparation of CNMs containing charge for efficient and cost effective removal of salt and solid suspended particle from brine feed resources.

In this work, CNM multilayers will be tailored with and without surface functionalization as electrodes in Capacitive Deionization (CDI) process to maximize the efficiency of the water purification technology. In addition, an innovative low energy -hybrid approach for CDI-filtration one step process, for waste water treatment is proposed, taking advantage the ballistic transport and surface area properties of the tailored multilayers CNMs.
