Assessment of the start-up of tubular reactors on a laboratory scale for the anaerobic digestion of slaughterhouse wastewater.

Abstract:

Slaughterhouse wastewater is a source of contamination due to its high content of organic matter, nutrients, and suspended solids. Anaerobic digestion (AD) is a biological treatment that reduces the organic load of liquid effluents and generates biogas. Plug flow reactors (PFR) are a technological alternative to simple design and implementation for continuous treatment. The research aims to compare the removal of chemical oxygen demand (RCOD) in the initial stage of anaerobic treatment of liquid waste in tubular reactors (TR) designed using the data of methane production kinetics. The slaughterhouse wastewater presented a methane yield of 468.21 NmLCH4.gCOD−1 during the methane biochemical potential assay. The volume of the TRs was 4.69 L (effective volume 3.51 L) and built-in PVC. The design of the considered 0, 2, and 4 baffles section to study their influence on the reactor start-up. The …
