Effective utilization of textile waste Abdul Karim Derbas, Racha Àrees temàtiques de la UPC::Enginyeria química Textile waste Sewage disposal plants Textile industrial waste Wastewater treatment plant Sludge Management Effluent Management Residus tèxtils Aigües residuals -- Plantes de tractament Aquest projecte pretén analitzar el millor enfocament dels residus industrials tèxtils de cotó generats a través d'una planta de tractament d'aigües residuals en termes de sostenibilitat i economia circular. Este proyecto tiene como objetivo analizar el mejor enfoque para los residuos industriales textiles de algodón generados a través de una planta de tratamiento de aguas residuales en términos de sostenibilidad y economía circular. Textile industrial process have been increasing along the population’s growth. Water is used as a primary resource in the manufacturing process, being involved in the wet processing stages. The amount of water that goes into the process is considerably high and as a result wastewater is produced. Wastewater treatment plants (WWTP) are responsible for purifying the effluent generated by this industrial sector. Taking this into account, this project aim to analyze qualitative and quantitative a cotton textile company that produces 600 m3 of wastewater and 127.743 kg of dry sludge daily. The effluent treated is dispersed in water bodies and the sludge generated is sent to the landfills. A more sustainable choice of management is proposed for both the treated effluent and the sludge based on the Waste Hierarchy Principle (WHP) imposed by European legislation. The effluent generated from the wastewater treatment plant met the discharge standards, however an additional treatment of disinfection is required for the reuse of this water within the cotton wet processing steps. The study conclude the most feasible sludge management, according to the sludge composition, where it is categorized under material recovery (dewatering, landspreading and composting), energy recovery( thermal processes) and disposal (landfill). Based on the WHP route proposed by the legislation and the composition of the sludge generated by the ETP, it was found that due the low organic material content, the most feasible solution is material recovery. Each alternative is analyzed quantitively and qualitative in order to find the most sustainable route.
