TAILIEUCHUNG - Quantification of pollutants mass and energy consumption as a tool for industrial wastewater pollution control in steel industry

Quantification of mass flows in production lines and waste treatment lines, as well as quantification of energy consumption at a factory is always challenges in cleaner production and pollution control decision making. The case study has conducted at a representative steel making complex in Vietnam, simulating the material flows of water and waste streams, and energy balance (EB) for water production and wastewater treatment processes, by using STAN (subSTance flow ANalysis) and SANKEY software, respectively. Input data were taken from secondary data sources, and additional monitoring of wastewater flows at the complex. COD was a selected parameter for material flow analysis (MFA) for evaluation of performance of wastewater treatment plants. Further, two scenarios were given for comparison of water and energy consumptions at existing and upgraded wastewater treatment plants. The results have shown that scenario 2, using disc filter (DF) and ultrafiltration (UF) membrane in combination with ultraviolet (UV) for improving quality of treated wastewater, could allow factory to reuse wastewater for production purposes. At the saved amount of fresh water 10,000 m3 /day by reuse of treated wastewater, the saved energy was 1, kWh/day. The quantitative flows of MFA and EB were clearly presented in STAN and SANKEY diagrams. | Quantification of pollutants mass and energy consumption as a tool for industrial wastewater pollution control in steel industry
