TITLE:

USE OF ELECTROMETHANOGENESIS AS A STRATEGY FOR pH CONTROL IN ANAEROBIC BIODIGESTION

KEY WORDS:

Electromethanogenesis; anaerobic digestion; electrolysis.

BIG AREA: Ciências Biológicas
AREA: Biotecnologia
SUMMARY:

It is more and more it is essential that we start to observe and take care of the environment in which we live, nature has repeatedly signaled that the exacerbated use of fossil fuels and waste disposal irresponsibly has been extremely harmful to our biodiversity, it is crucial that we increasingly seek sustainable alternatives for the use of natural resources in addition to using systems that promote the treatment of disposal waste. In that regard, The present work aims to present the development of a bioreactor capable of automatically controlling the pH of the waste through an electrolysis system. Therefore, this research aims to investigate how microbial electrolysis behaves as a pH control agent in anaerobic digestion. At first, a bioreactor was established to start the analysis of methanogenic activity, subsequently, the procedure for measuring the pH and the volume of biogas produced will be carried out, therefore, will be measured using a dome gasometer, therefore, a control system based on electrolysis cells will be inserted in order to promote electromethanogenesis in the reactor, this process aims to increase biogas productivity in addition to controlling the pH, increasing the organic rate and decreasing the hydraulic detention time, consequently increasing the efficiency of the reactor. Therefore, a control system with a microcontroller will be used “Arduino” which will enable the automation of a potentiostat device responsible for applying a certain voltage/potential level in the bioreactor.
