Peter Goethals, Ghent University: “What we are going to do is combine different filtration methods and see what works best. And in this way, with as few resources as possible, the water efficiently purifying.”

Franky Demon, ships of Public Domain Bruges: “If the filter runs, thousands of liters of water can pass through it per hour. But that is of course a huge consumption, a huge cost price. We have to see: what is the cost price compared to the return?”
