Biological phosphorus removal at an experimental full-scale plant in France

Abstract: In France, all phosphorus removal treatment has been based on precipitation by means of chemical reagents. With a view to reducing costs, a series of laboratory experiments was initiated and subsequently followed up by full-scale studies in early 1984 at the Saint-Mars-la-Jaille treatment plant. This is the first biological P-removal plant to be put on line in France.The plant operates at low loading levels with extended aeration. Nitrification-denitrification is achieved in controlled aerobic and nonaerobic z… Show more

“…Where initially it would seem logical to find higher efficiencies at elevated temperatures (20-37 1C) (Yeoman et al, 1988;McClintock et al, 1991;Converti et al, 1995), various researchers report on improved efficiencies at lower temperatures (5-15 1C) (Barnard et al, 1985;Florentz et al, 1987). In particular, when considering EBPR efficiency at different temperatures, results from literature show contrasting observations.…”

“…La liberación de fosfatos empieza a valores entre 0.1 y 0.5 mg/L de O2, pero cuando existe limitación de oxígeno disuelto, la presencia de nitratos reduce la liberación de fosfatos en la zona anaerobia en plantas de baja carga (con nitrificación y desnitrificación) pero no en plantas con alta carga (sin nitrificación) (165). La eliminación de nitratos aumentaba la liberación de fósforo en la fase anaerobia provocando una alta acumulación de fósforo en la fase aerobia (61). Es importante que la zona anaerobia no reciba nitratos, ya que si se añade algún sustrato se oxidará en la reacción de desnitrificación (147).…”
