Treatment of wastewater from anaerobic digestion
The Client The customer is power plant which produces biogas from biomass and sewage farm, through anaerobic digestion and thermal recovery, located nearby Munich in Germany. The Client’s needs Biogas is produced by the fermentation of organic substances of animal and vegetal origin in absence of oxygen (anaerobic process). This process produces a stream called digestate which is an ...

Anaerobic co-digestion of surplus yeast and wastewater to increase energy recovery in breweries
Surplus yeast is a residue produced during brewery process, which presents high contents of organic matter. Biogas production from yeast could significantly contribute to bioenergy production in breweries, via biogas generation. Co-digestion of surplus yeast and brewery wastewater in a single treatment step would simplify the technical and economical requirements for the transformation of both ...

Treatment of corn ethanol distillery wastewater using two-stage anaerobic digestion
In this study the mesophilic two-stage anaerobic digestion (AD) of corn bioethanol distillery wastewater is investigated in laboratory-scale reactors. Two-stage AD technology separates the different sub-processes of the AD in two distinct reactors, enabling the use of optimal conditions for the different microbial consortia involved in the different process phases, and thus allowing for ...

Where To Find Money In Biogas
On the surface, wastewater treatment operations don’t appear to be handling precious material. But these facilities are actually processing a great deal of value every day. Sludge, a byproduct of wastewater treatment, turns out to be an entity worth cherishing. “Depending on treated sludge quality, the final product can be land applied, landfilled, incinerated, or composed,” ...

Q-Calc: A new App for managing food waste
Many wastewater treatment plants are intrigued with the idea of increasing biogas production by accepting food waste, but are concerned with process stability. As part of a Phase I SBIR from the USDA, Quantalux is developing a software decision tool called Q-Calc that provides operators with the ability to predict the digester’s health and stability when adding food waste to manure or ...

The elimination of siloxanes from the biogas of a wastewater treatment plant by means of an adsorption process
Siloxanes present in the biogas produced during anaerobic digestion in wastewater treatment plants (WWTPs) can damage the mechanism of cogeneration heat engines and obstruct the process of energy valorization. The objective of this research is to detect the presence of siloxanes in the biogas and evaluate a procedure for their elimination. A breakthrough curve of a synthetic ...

SENTRY-AD: Real-time Monitoring of the Impact of Cleaning Agents on Performance of Anaerobic Digestion Systems Case Study
SENTRY-AD bio-electrode sensor that allows for the monitoring of microbial metabolic activity in the anaerobic digestion (AD) wastewater treatment process. The data generated by the bio-electrode sensor allows operators to monitor the impact of toxic chemicals on microbial health in the AD system. Cleaning agents, biocides, are used for equipment and container sterilization in the food and ...

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 ...

Increased biogas production in a wastewater treatment plant by anaerobic co-digestion of fruit and vegetable waste and sewer sludge – A full scale study
Anaerobic digestion is a well established technology for the reduction of organic matter and stabilization of wastewater. Biogas, a mixture of methane and carbon dioxide, is produced as a useful by-product of the process. Current solid waste management at the city of Prince George is focused on disposal of waste and not on energy recovery. Co-digestion of fresh fruit and vegetable waste with ...

Saving energy and eating better
The US consumer wants food to be fresh, local and organic. But that means larger grocery bills in an economy where most people need them to be smaller. As the New York Times tells it, 20-somethings, just out of college, feel the squeeze the most. They are more intent on Whole Foods-style eating than their predecessors, but less able to afford it. (See “The Unaffordable Luxury of ...
