Methods for anaerobic digestion model fitting—comparison between heuristic and automatic approach

Meta Heuristic Approach for Automatic Forecasting Model Selection

Selection of appropriate forecasting models with their optimized parameters for a given business scenario is a challenging task and requires reasonable expert knowledge and experience. The problem of selecting the best forecasting model becomes computationally complex when the business needs forecasts on thousands of time series at a given time period. Many a times business users are interested...

Pretreatment Methods in Anaerobic Digestion for Biogas Generation: A Review

Biogas energy has got importance in the field of energy engineering because of its attractive features. Biogas is produced from different types of waste materials by the process of Anaerobic Digestion. This paper gives the insight of Anaerobic Digestion process and different pretreatment methods used in various experimental research works. Flower waste is also a potential source of biogas energ...

Anaerobic digestion

Application of Anaerobic Digestion Model No. 1 for describing anaerobic digestion of grass, maize, green weed silage, and industrial glycerine.

Anaerobic digestion of organic waste plays an important role for the development of sustainable energy supply based on renewable resources. For further process optimization of anaerobic digestion, biogas production with the commonly used substrates, grass, maize, and green weed silage, together with industrial glycerine, were analyzed by the Weender analysis/van Soest method, and a simulation s...

Automatic control of VFA in anaerobic digestion using a fuzzy logic based approach

A control law based on Fuzzy Logic was developed and validated for an anaerobic wastewater treatment process. The controlled variable was the concentration of Volatile Fatty Acids (VFA) in the reactor and the manipulated variable was the input flow rate. In order to use it as the input of the fuzzy sets, the controlled variable was treated using an algorithm of interpolation, extrapolation and ...
