The Biodynamic Treatment of Wastewater

Abstract

A wastewater treatment is proposed. It is based on: 1. The assumption that the changes taking place during the transformation of wastewater into effluent are unidirectional processes, entailing a number of well- defined sequential stages, and 2. The knowledge that the aerobic bacterial populations present in wastewater are able to decompose efficiently the organic matter in the wastewater, given optimal conditions for their development. Preliminary experiments in which these assumptions have been tested showed the production of a high quality effluent, as measured by the conventional chemical, physical and public health standards. No pathogenic bacteria or human enteric viruses have been recovered from the effluent so produced. A comparison between the processes of the "conventional biological" and a "biodynamic" treatment will be presented.
