Resumen
Stabilisation ponds are the most frequently used wastewater treatment technology in Argentina. This study focuses on the performance of two maturation ponds (MPs) that are part of the full-scale sewage treatment system of Puerto Madryn. Seventy-seven shots of surface water were analysed for organic matter, inorganic nitrogen, phytoplankton dynamics and bacterial removal. The system presented a clear evolution with respect to oxygenation and phytoplankton development. The treated wastewater reached values above 8 mg-O2/L, an important organic matter removal, and this was accompanied by a strong increase in pH. NH4 + removal and oxidation, was active even during winter in the MPs, with average concentrations below 10 mg - NH4 + /L. Bacteriological removal resulted in a liquid that approached the WHO recommendations for unrestricted irrigation. These results show that is possible to generate treated wastewater in stabilisation ponds working in a semiarid and temperate region, with bacterial content and conductivity suitable for irrigation.
