Abstract
Grey water footprint was figured out for five scenarios and existing treatment process without reuse and with reuse process for a dye industry wastewater treatment plant. In this study, five treatment scenarios that include an electrocoagulation process (scenario-1), a Fenton process (scenario-2), a membrane distillation process (scenario-3), a reverse osmosis (scenario-4) and an ozonation process (scenario-5) were studied. Grey water footprint assessment was undertaken using Water Footprint Network method without reuse process. Then, Monte Carlo simulation was applied for the minimum grey water footprint. Finally, the grey water footprint was assessed with the reuse process. According to the results, the grey water footprint was found to decrease upon applying the reuse process. A significant reduction was approximately 182.5% with the reuse process for existing process. The results revealed that scenario-4 has the smallest grey water footprint value and scenario-1 has the highest grey water footprint value, after the reuse process.
