Electrochemical treatment of problematic water recycle waste streams (2009-2012)
Abstract
To secure future fresh water supplies, indirect potable reuse of treated domestic wastewater is rapidly increasing worldwide. Indirect potable reuse depends heavily on filtration via reverse osmosis (RO) membranes. This produces a concentrate stream, with potentially elevated levels of recalcitrant pollutants (pharmaceuticals, organic nitrogen compounds etc.) which are difficult and expensive to remove using existing technologies. We will assess the hazards posed by this concentrate, and develop an electrochemical treatment that is non-selective and is significantly lower in operating cost than conventional technologies. This treatment will be tested at pilot scale.'',
