Application of super-twisting observers to the estimation of state and unknown inputs in an anaerobic digestion system
This paper presents the estimation of the unknown states and inputs of an anaerobic digestion system characterized by a two-step reaction model. The estimation is based on the measurement of the two substrate concentrations and of the outflow rate of biogas and relies on the use of an observer, consisting of three parts. The first is a generalized super-twisting observer, which estimates a ...

Modelling start-up performance of anaerobic digestion of saline-rich macro-algae
Some of the key factors affecting the adaptation of anaerobic digestion processes to increasing levels of salinity were determined in batch tests using brown seaweed as a feedstock. It was found that cultures seeded with non-saline anaerobic inoculum required an adaptation period of up to two months to reach the same level of methane production rate as in those cultures seeded with ...

Feasibility of high solid anaerobic digestion: option for treatment of distillers grains from cassava ethanol production
This research article mainly focused on the feasibility and management of distillers grains produced from ethanol industries using high solid anaerobic digestion systems. A significant barrier for distillers grains in the anaerobic process are its low pH (3.80–4.16) and high C/N ratio (37/1–42/1). According to distillers grains characteristics, the stillage investigated was in dry form (TS 23% to ...

Fate of pathogen indicators in a domestic blend of food waste and wastewater through a two-stage anaerobic digestion system
Anaerobic digestion is a viable on-site treatment technology for rich organic waste streams such as food waste and blackwater. In contrast to large-scale municipal wastewater treatment plants which are typically located away from the community, the effluent from any type of on-site system is a potential pathogenic hazard because of the intimacy of the system to the community. The native ...

Modelling of anaerobic digester biogas production: case study of a pilot project in Morocco
An anaerobic digestion pilot system was implemented in June 2010 in the Moroccan village of Dayet Ifrah. The input material consists of toilet wastewater and cattle manure. Biogas is produced under anaerobic conditions. It is used for heating and cooking. This biogas system could be an useful sanitation technology due to its ability to treat wastewater. The biogas system was monitored over 86 ...

Turning waste into power
Economic, social and environmental factors dictate the necessity to manage waste to a new level. Wastewater plants, landfills, farms and food plants are all the owners of biomass that can be digested to produce biogas and turned into power. Biogas can be burned directly in boilers for heat recovery and used for manufacturing, heating or cooling; this is the simplest method of direct biogas ...
