tailieunhanh - Material flow analysis and energy balance analysis as technical tools for wastewater pollution control in textile and dyeing industry – A case study

Quantification of material flows and energy balance in production lines as well as in waste management systems and illustrative presentation of the flows are useful tools for decision making in both cleaner production and pollution control. In this study, using STAN software, the authors have analyzed the material flows, and, using SANKEY software, the authors have analyzed the energy balance of the main production lines and the wastewater management system of a selected textile company in Vietnam. Comparing with “business as usual” scenario, a new scenario with reuse of treated wastewater has been introduced. Loadings of the main pollutants in wastewater as Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), Total Phosphorus (T-P) and Total Nitrogen (T-N) were , , and ton/year, respectively. One meter of produced fabric consumed m3 of water. The energy consumption rate was kWh per m3 of wastewater treated. Ultrafiltration and ion exchange could enable reuse of wastewater. It could save kWh per day of electricity and 1, m 3 per day of fresh water to be taken from the river. Ozonation was the most consuming energy process at the wastewater treatment station, accounting for % of total wastewater treatment energy consumption. | Material flow analysis and energy balance analysis as technical tools for wastewater pollution control in textile and dyeing industry A case study
