Simulation Platform
Description
Fit4Reuse simulation platform was designed to simulate simplified models of the Fit4Reuse solutions as a tool mainly for decision making. The simulation platform will be suitable to simulate different scenarios for different cases, applications in different regions with different requirements and obligations. The simulation platform is capable of simulating single units together with the innovative enhancements and also the process trains composed of different units. The simulations will reveal system performance in terms of water quality, energy and carbon footprint.
