Production and characterization of H2S and PO43− carbonaceous adsorbents from anaerobic digested fibers

Anaerobic digestion (AD) is an important technology to produce biogas from dairy manure. Although the AD of dairy manure results in the harnessing of the energy contained in manure, most of the nutrients (phosphorous and nitrogen) remain in the liquid effluent, representing an important source of pollution. Additionally, the biogas produced contains H2S and CO2, limiting its practical use as fuel. In this paper, we report the production and use...
