Membrane System Design Software


The Winflows design software is an intuitive and user-friendly simulation program that allows users to quickly design simple or complex reverse osmosis (RO), nanofiltration (NF), and electrodeionization (EDI) systems. The software provides exposure to Veolia’s spiral wound RO/NF membranes and E-Cell EDI stacks along with extensive cartridge filters products as well as pre-engineered NF and RO systems.
