New technology is needed to ensure water reuse, reduce energy consumption, or energy production and enables the reuse of the components present in water. Only recently, nanotechnology is being explored for application in the water technology area. Current water technology is not adequately equipped to cope with the big challenges of energy and food security. This technology focuses primarily on water purification only and consumes a great deal of energy.
Given the big challenges and the innovative opportunities, nanotechnology seems to be well positioned to deliver breakthrough innovations. Nanotechnology makes it possible to convert contaminated surface water in water of the desired quality, for example. Membranes filter dust particles, micro-organisms and organic material from the water. Nanotechnology enables the production of pores in these ultra-fine membranes with even greater precision, so that almost 100 percent of micro-organisms is removed.
