Abstract
Brazil is the largest sugar and alcohol producer in the world, consequently, it is also a major vinasse producer, which is a problem, as it has a high potential for pollution, severely impacting the soil and water, despite being used in fertigation of cane fields. When treated in anaerobic conditions, however, it can produce energy and be used as a biofertilizer for the soil. This treatment can be performed by an Upflow Anaerobic Sludge Blanket (UASB), considered efficient by the literature. Based on this, this article tries to gather equations and collect data, reviewing the scientific literature with the objective of designing an UASB for the treatment of vinasse, exposing an alternative of suitable final disposal for this by-product. The results show good opportunities, with a great potential for reducing BOD and COD and producing biogas, electricity and biofertilizer, in addition to providing a compilation of equations and important data for future calculations.
