Advancing Water Treatment Technologies to Impact the Water-Energy Nexus

International Society for Water Solutions - ISWS
Originally delivered Oct 8, 2013

Clean water and on-demand energy are intimately intertwined. This talk covers technical challenges and solutions for water treatment across broad component technologies (reverse osmosis, ultrafiltration, ion exchange, and macrofiltration). Case studies with a global focus are presented on minimizing natural water withdrawal and wastewater disposal, as well as minimizing energy consumption in several end-use applications. 

Water is required to make use of energy and energy is required to make use of water. Globally, water is required in virtually everything we touch from growing and processing food to industrial processes that require energy.  Energy production relies on large amounts of water. Alone in the U.S., electricity production from fossil fuels and nuclear energy requires 190,000M gal/d, accounting for 39% of all freshwater withdraws. In industrial applications, water is used in products itself or used for washing, cooling, heating or steam generation within various industry types such as steel, automotive, textile, beverage, electronics, pulp and paper, refining, and chemical. Common to these processes is that they are large water consumers and depending on the process, the water needs can vary greatly. The need to increase the efficiency of water treatment systems is driven both from economical and sustainability aspects. The drivers for change are increasing price of water and the access to good quality water in close proximity to factories, especially in areas suffering from natural water scarcity.
