Lagunas de estabilización para tratamiento de aguas servidas

Abstract

This article describes a system for the treatment of sewage by means of a stabilization pond for anaerobic treatment at the lower level and aerobic treatment at the upper level, preceded by simple mechanical aeration. The author points out the ability of this process to tolerate great differences in organic loads which are so frequent in industrial sewage

Everything possible has also been done to take into account the economic and climatic conditions of communities in which treatment plants are constructed as well as local practices and methods of managing and operating such systems which will be later reflected in their actual operation. Prior examination will make it possible to adopt the most realistic solutions and the result will be more efficient use of available resources

The author also points out that in principle, because of their low initial cost, low cost of operation and maintenance, and high degree of efficiency, stabilization ponds can be successfully employed for the treatment of effluents from factories and communities in different parts of Mexico whose organic load is less than 30 mg/1

Anaerobic or aerobic stabilization ponds, whether constructed to work in series or in parallel, can be successfully used as the sole means of treatment or in combination with simple aerators. As a rule, the most important construction items such as the purchase of land and labor costs do ...(AU)
