Abstract

This paper presents the basic technology developed for a cylindric pilot reactor with 80 cm long and 70 cm of diameter. The reactor ís a closed system, equipped for total control of the aeration process during the aerobic degradation of the solid organic residues. The automatisation of air flow is done by a PLC, connected to a computer which stores data on temperature, air flow, 02 level in exit gases and increments of air flow. As an illustration, the data of an experiment using sewage sludge and wood residues, are presented. The purpose of this pilot reactor is to study the biodegradability of organic residues and to determine project  parameters for real scale composting plants.
