Improvement of Anaerobic Digestion of Sewage Sludge, Using Combined Hydrogen Peroxide and Thermal Pre-Treatment
The present study investigates the influence of individual and combined hydrogen peroxide and thermal pre-treatment of waste activated sludge on anaerobic digestion. For so doing, it employs anaerobic batch reactors in the mesophilic conditions. For comparison, soluble fractions of organic matter, biogas production, biochemical methane potential, removal of chemical oxygen demand (COD), and vol...

متن کاملEvaluation of pre-treatment efficiency of fats, oils and greases using low frequency ultrasonic waves to accelerate the process of anaerobic digestion
Background and Objective: Hydrolysis of fat, oil and grease by ultrasonic waves is a pre-treatment method before anaerobic digestion which can change their physical, chemical and biological properties. The main purpose of this study was to investigate the efficiency of ultrasonic waves to improve the hydrolysis process and its use as an auxiliary substrate to increase the efficiency of anaerobi...
متن کاملComparative assessment of single-stage and two-stage anaerobic digestion for the treatment of thin stillage.
A comparative evaluation of single-stage and two-stage anaerobic digestion processes for biomethane and biohydrogen production using thin stillage was performed to assess the impact of separating the acidogenic and methanogenic stages on anaerobic digestion. Thin stillage, the main by-product from ethanol production, was characterized by high total chemical oxygen demand (TCOD) of 122 g/L and t...
متن کاملTwo-step Parameter and State Estimation of the Anaerobic Digestion
Abstract: This paper is devoted to the state and parameter observation for anaerobic digestion process of organic waste. The observation has a two-step structure using separation of acidogenic stage from the methanogenic phase. Two observers and one estimator are built on the basis of a mass-balance nonlinear model of the process, involving a new control input, which reflects the addition of a ...
