| Sumario: | The environmental crisis in our contemporary, globalized world, is facing a paradigm: the company now has a major technological development, and is also a society that destroys most in history. All the achievements of our civilization provide various negative factors, such as fast-paced population growth, depletion of natural resources, expansion of consumption of materials and production systems that use polluting production processes and waste, which if not treated and/or properly designed produce imbalances in the biosphere, changing vital ecosystems. In seeking solutions to the disposal of waste organic solids, we find that the composting process can be considered one of the most appropriate alternatives in the environmental point of view, promoting greater recycling and more appropriate in terms of material and energy when compared with other methods. This search of the society for better environmental conditions, points to a tendency to experience a substantial increase in the amount of sludge to be disposed of in the coming years, it appears, therefore, need to be presented techniques that allow an efficient and adequate treatment of them. The use of the composting process in Brazil is still very limited, the high degree of empiricism used in the control and evaluation process for lack of more indepth technical knowledge, not giving rise to the implementation of new forms of analysis and effective control. In the evaluation process called the method "respirometric", uses a new methodology in which the parameters of biological degradation of waste is not measured in the solid phase, but in the gas phase. The analysis in the gas phase has the advantage of greater representativeness, precision and reliability, to be totally homogeneous. The parameters measured in the gas phase of the composting process of sewage sludge, determine the temporal evolution of O2 consumption and CO2 and their generation, these gases are analyzed, recorded, the data are sent to a computer that displays the results instantly. |
