Estimación de curvas de caudal para el diseño de sistemas de tratamiento de aguas residuales

Abstract

This article presents eight curves of waste water generation, 2 in commercial buildings, 2 in office buildings, 2 in residential establishments, 1 in food industry, and 1 in a university. Curves are presented in terms of percentage of the total flow in a day. They were estimated by measuring instantaneous flow every 5 minutes during 24 hours, in order to establish the difference in the wastewater flow that enters to wastewater treatment plants of each kind of wastewater generator. Values obtain were processed to produce graphics in 30 minutes range time. In every case, average flow is equivalent to 2.1% of the total flow in a day. Commercial discharges present peak flow of 2.4 to 3.6 times average flow; office buildings discharges present peak flow of 2 to 2.1 times average flow; and residential discharges presents peak flows of 1.9 to 2.2 times average flow.
