    Encuesta sobre Plantas de Tratamiento de Efluentes Líquidos en Argentina: Aspectos Socio-Culturales
    (XXXVII Congreso Interamericano Virtual de Ingeniería Sanitaria y Ambiental, 2021-04) Nizza, C. ; Lee, H.; Sabels, M. ; Burlaka, M. ; Calvo, D. ; Affranchino, G. ; Rossen, A.
    The present work belongs to an interdisciplinary research project carried out collaboratively between the Technological Institute of Buenos Aires and the National Water Institute, regarding the evaluation of the current operative situation of the effluent treatment plants in Argentina. Different aspects of the performance, innovation and technical capacities were revised in a carefully-designed survey. Besides, a sociological section, presented in this work, was included so as to generate evidence about their operational and cultural modalities of the wastewater treatment sector. From the surveys received (65), 41% of the cases are registered in two or more environmental control agencies, and there is a widespread overlap among different agencies responsible for wastewater discharge quality values measurements ​​(58%). Around 57% of the cases carried out significant technological innovations during the last 10 years, and only 15% required specific knowledge from their operators to perform specific tasks. Smaller percentages were obtained regarding capacitation plan to new employees (36%), and the incorporation of specific training and / or updating courses (29%). Considering issues related to environmental protection, the compliance percentages are far from the total, with 40% of the plants reporting an insufficient budget. Given these results, and within the framework of the Sustainable Development Goals of the UN 2030 Agenda, the challenge will be to form a permanent matrix of interrelationships between scientific evidence, professionalism and the role of stakeholders of the industrial sector and the State, in order to promote policies that guarantee a greater efficiency and environmental commitment of the sector.

    Encuesta sobre plantas de tratamiento de efluentes líquidos en Argentina: aspectos técnicos
    (XXXVII Congreso Interamericano Virtual de Ingeniería Sanitaria y Ambiental, 2021-04) Affranchino, G. ; Hyo Jee, L.; Sabels, M. ; Nizza, C. ; Burlaka, M.; Calvo, D. ; Rossen, A.
    Wastewater discharges represent one of the most relevant sources of water pollution. Different operation problems at WWTPs (Wastewater Treatment Plants), can reduce the effectiveness of depuration processes. These problems are preventable with correct monitoring and analysis techniques that operators must implement. We conducted a complete survey to collect information on WWTPs in Argentina. Some of the topics were related to different types of effluent treatment, management strategies, fundamental analysis protocols and recurrent operation troubles. The main difficult referred for activated sludge plants, is the escape of solids caused by clumping and foaming phenomena. For anaerobic treatments, the lack of adequate biomass predominates in addition to low pH situations. For lagoons, the main issues are excess of organic load and sediment clogging. Bad quality treated water, usually responds to high levels of COD and BOD, too much phosphorus and –frequently mentioned– poor organoleptic properties.
