Resumen
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.
