The problems concerned with waste management abound in most regions of the world, and so, efforts must be made to assess the global level of pollution and to understand the major factors involved in order to propose efficient waste treatment technologies. This must be compatible with environmental and economic conditions and appropriate to semi-urban settlements, isolated communities and a variety of industrial situations.
The main purpose of this paper is to present recent waste management technology as an alternative solution to traditional treatment systems in regions where those systems are not economically or technically feasible, using for this purpose the advantages of climatic conditions (air temperature, relative humidity and wind speed).
This integrated technology combines two different processes: optimization of the solid/liquid separation, using a decanter, followed by the utilization of evaporation panels to eliminate the liquid fraction of the effluent, optimizing by this way the evaporation phenomenon, which is so important and resolute in certain cases, that it is absurd not to exploit it intensely.
The technology presented was followed by a research programme developed in the last three years, implemented in an agro-industrial unit located in a high polluted area of Portugal, with the aim to evaluate its efficiency and optimize the performance parameters. The conclusions of this research programme emphasized the importance of the evaporation phenomenon as a simple solution to deal with complex environmental problems.
