The relationship between the production of biogas and biol from trout waste and cow manure

Abstract

This study analyzed the relationship between the production of biogas and biol from trout waste and cow manure. The treatments evaluated contained different amounts of manure, T1 (6 kg), T2 (12 kg) and T3 (24 kg), of which the treatments which produced the highest quantity of biogas and biol were T3>T2>T1>Control, in descending order. Therefore, it was shown that the T3 treatment produced the best results for both variables. With regard to the amount of accumulated biogas for this treatment, total production was 159.3 l. The composition was defined by concentrations of nitrogen, potassium, calcium, magnesium and sodium (6600, 565.89, 1136.67, 1603.33, 563.33 and 408.33 mg.l-1, respectively), while the percentages of humic and fulvic acids, and humins were 1.06%, 1.39%, 0.48%, respectively.
