Abstract

More and more interest is being dedicated to anaerobic processes in the scientific literature; in particular, high velocity reactors, such as the Up-flow Anaerobic Sludge Blanket reactor, are able to reduce the required HRT and to optimize biogas production. This kind of reactors is particularly indicated for high concentrated wastewaters, in which the soluble fraction is prevalent over the suspended one. In this cases, the anaerobic process can achieve high efficiencies, in terms of COD removal, with low energy requirements, if compared to a traditional activated sludge process. This work is focused on Tolmezzo wastewater treatment plant, because it contains a UASB reactor, that is inactive since 2007, and so it is, potentially, a source of clean energy. It is supposed to feed the reactor with the liquid fraction of Organic Fraction of Municipal Solid Waste (OFMSW), separately segregated in the local geographic area, while the solid fraction, residual from the separation process, is suitable to be sent to a composting plant.
