Each year, ethanol production
is increasing in Brazil, consequently, the generation of byproducts as well.
Among these, the vinasse stands out. With polluting power a hundred
times greater than domestic sewage and high concentration of minerals, vinasse is generated in large volumes. Because of these characteristics,
it is widely used in fertirrigation. However, it is composed of about 97% water,
inflating the cost of the transport from the plant to the field. For these reasons,
removing water from the vinasse and the consequent concentration of solids is an
alternative management and application of this by-product. This project aimed to
analyze the efficiency of various physical and chemical processes in the removal
of water from the vinasse.
