AQUAFIT4USE is a large-scale project funded under the 7th Framework Programme (FP7), a grant funding programme of the European Commission. It aims to make industries more independent of the supply of water for their production processes. The initiative aims to develop new technologies, tools and methods for sustainable water supply, use and discharge in the main water consuming industries: in other words “water fit-for-(re)use”. These new techniques encompass innovative technologies or applied technologies dealing with water looping in the four following industries: paper, food, chemistry and textile.
