Biodigestores por bombonas para tratamento de esgoto doméstico.

Abstract

Access to basic sanitation is still very precarious in Brazil, due to the lack of water treatment, and inadequate sanitation and hygiene, in a scenario like this, biodigesters present themselves as a low-cost alternative to minimize soil contamination, wells and hydrographic basins, and thus improve the lives of Brazilians and consequently the country's economy. The objective of this work was to demonstrate the environmental and economic viability of the use of biodigesters reusing canisters. A bibliographic research was carried out on the use of low-cost biodigesters, manufactured with recycled drums, for the treatment of domestic sewage. the use of recycled drums is sustainable, in addition to being economically viable, when compared to the cost of implementing and maintaining a septic tank made of concrete, masonry and prefabricated biodigesters supplied on the market.
