Influence of a steam-explosion pre-treatment on the

digestion of the two-phase olive mill solid waste (OMSW) or alperujo. The OMSW was subjected to a steam explosion pre-treatment at 200ºC and 16 kg/cm2 (1.57 MPa) during 5 min. After this pre-treatment a solid fraction (SF) and a liquid fraction (LF) were generated. These two fractions were used to obtain methane through anaerobic digestion

Anaerobic Co-Digestion of Wastewater Sludge A Review of

Anaerobic digestion has been widely employed in waste treatment for its ability to capture methane gas released as a product during the digestion. Certain wastes, however, cannot be easily digested due to their low nutrient level insufficient for anaerobic digestion, thus co-digestion is a viable option. Numerous studies have shown that using co-substrates in anaerobic digestion systems

Anaerobic Wastewater Treatment Evoqua

Anaerobic digestion is a process in which microorganisms convert organic matter into biogas in the absence of oxygen. It is an energy-efficient process that is typically utilized to treat high-strength industrial wastewater that is warm and contains high concentrations of biodegradable organic matter (measured as BOD, COD, and/or TSS).

Anaerobic co-digestion of olive mill wastewater with olive

Anaerobic co-digestion is a well established process for treating many types of organic wastes, both solid and liquid. In this study we have investigated, on a laboratory scale, the anaerobic co-digestion of olive mill wastewater (OMW) with olive mill solid waste (OMSW) using semi-continuous, feeding, tubular digesters operated at mesophilic temperatures.

Olive mill solid waste (OMSW) is a pollutant waste coming from olive oil elaboration by the two-phase centrifugation system. OMSW has a high organic matter content and unbalanced carbon to nitrogen (C/N) ratio, 31/1, which avoids obtaining high methane yields in the anaerobic digestion of this waste.

Anaerobic digestion (AD) is a biological process similar to composting, but without air. As in composting, micro-organisms break down organic matter into simpler smaller compounds and reduce its bulk or "mass". However, unlike composting, which overall always consumes energy, anaerobic digestion can be used to create energy.
