Water network optimisation in the process industry—case study of a liquid detergent plant

The main target of this research project is the optimisation of the water management in a liquid detergent production plant according to the concept for retrofit optimisation of water networks (CROWN) strategy in order to reduce freshwater consumption and the costs for wastewater disposal. A membrane process and a disinfection step are integrated into the water network in order to recycle process water and to recover concentrated product solutions.
