EFICIENCIA EN LA REMOCIÓN DE NITRÓGENO Y FÓSFORO EN LOS FILTROS PERCOLADORES DE LA PLANTA DE TRATAMIENTO DE AGUAS RESIDUALES DE LA UNIVERSIDAD DE SAN CARLOS DE GUATEMALA – USAC –

Abstract

In this article it is show the efficiency gains obtained in the system of trickling filters for removal of total nitrogen and total phosphorus, as well as some its forms. In the Wastewater Treatment Plant of University of San Carlos of Guatemala the average flow is 3,92 l/s between the months of october 2012 to January 2013, with an average rate of 0,55 biodegradability. It is important to evaluate the cycle nitrogen and phosphorus results were achieved which indicated that between stage I and stage II occurs nitrification and between stage II and III gives the denitrification step, which helps to reduce nitrogen values total an average of 20,5%. In the case of total phosphorus is removed 11,5% of its initial value.
