Metodologia analítica para a determinação de sulfato em vinhoto When sulfate is present in high concentrations, it acts as an inhibitor in the production of methane (biogas formation) in anaerobic biodigestion processes

Química Nova, 1998
In this way it is very important to know the sulfate concentration in vinasse samples before to make the biodigestor design. A previous developed and indirect method (Anal. Chim. Acta. 1996, 329, 197), was used to determine sulfate in samples of vinasse,

Mathematical models of anaerobic digestion for the treatment of swine effluents

Pesquisa Agropecuária Tropical, 2015
Pig breeding results in the production of large amounts of waste, which can cause serious environmental problems, when handled incorrectly. This study aimed at testing mathematical models to estimate the parameters of anaerobic biodigestion in ...

PRODUKSI BIOGAS DARI KOMBINASI KOTORAN KAMBING DAN LIMBAH IKAN DALAM BIODIGESTER ANAEROB

Envirous, 2023
Penumpukan limbah ikan pada pembuangan di pasar ikan mencemari lingkungan dan mengurangi estetika lingkungan. Pengolahan limbah ikan secara anaerob merupakan cara yang efisien karena mengandung protein, lemak dan konsentrasi bahan organik tinggi. Dengan nilai rasio C/N yang rendah limbah ikan harus dicampur dengan kotoran ternak atau tumbuhan hijau ...

Optimizing food waste biodigestion: pre-selection of microbial groups and isolated enzymes using the plackett-burman experimental design

Observatorio de la Economía Latinoamericana, 2023
This study investigated the use of anaerobic biodigestion as an ecological technique for treating organic waste in urban solid waste. Biogas production is carried out through the action of microorganisms, and the use of enzymatic hydrolysis can increase ...

Agricultural recycling of biodigested vinasse for lettuce production

Revista Ambiente & Água, 2014
The agricultural use of waste products represents an interesting alternative for nutrient cycling. Biodigested vinasse, the final waste product of vinasse biodigestion and biogas production, can be reused for agricultural purposes.

Biogas production and electricity generation from a quail manure wastewater treatment system per water depth [PDF]

, 2023
Coturniculture, as an activity which demands low investment and quick return, is shown to be a possibility for the rural family producer. Concomitant to this, we highlight the fact that the use of liquid quail farming waste, aimed at generating energy by

Biogas Production Using Anaerobic Biodigester from Cassava Starch Effluent

International Journal of Science and Engineering, 2010
IKMs’ factory activity in Margoyoso produces liquid and solid wastes. The possible alternative was to use the liquid effluent as biogas raw material. This study focuses on the used of urea, ruminant, yeast, microalgae, the treatment of gelled and ungelled feed for biogas production, pH control during biogas production using buffer Na2CO3, and feeding ...
