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 ...

GTI’s cover for the town of Creston lasts 20 years - case study
The Town of Creston, British Columbia, Canada, operates an anaerobic digester to treat brewery wastewater. Biogas is used to fuel a boiler for process heating. The system was approaching 20 years old and the cover, originally built by GTI, required replacement. The anaerobic digester had to remain in service while the covers were changed. The cover was replaced with an updated GTI gas collection ...

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 ...

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 ...

Modelling anaerobic digestion of concentrated black water and faecal matter in accumulation system
A dynamic mathematical model based on anaerobic digestion model no. 1 (ADM1) was developed for accumulation (AC) system treating concentrated black water and faecal matter at different temperatures. The AC system was investigated for the treatment of waste(water) produced from the following systems: vacuum toilet for black water (VBW), vacuum toilet for faeces with urine separation (VF), dry ...

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 ...

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 ...

Anaerobic digestion of post-hydrothermal liquefaction wastewater for improved energy efficiency of hydrothermal bioenergy processes
Hydrothermal liquefaction (HTL) is a promising process for converting wet biomass and organic wastes into bio-crude oil. It also produces an aqueous product referred to as post-hydrothermal liquefaction wastewater (PHWW) containing up to 40% of the original feedstock carbon, which reduces the overall energy efficiency of the HTL process. This study investigated the feasibility of using ...

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,” ...

Case study - Grand Junction Sets the Pace with Colorado’s First Biogas-to-Vehicle Fuel Project at the Persigo Wastewater Plant
The first biogas-to-vehicle fuel project in Colorado converts wastewater-derived biogas mto renewable natural gas (RNG) to fuel city and county fleet vehicles Summary: The Per si go wastewater treatment plant in Grand Junction, Colorado, a city of about 60,000, processes upwards of 8.2 million gallons per day of wastewater in two anaerobic digestion tanks (primary and secondary). The facility ...

Biogas Treatment in WWTP
Wastewater treatment plants (WWTPs) are facilities that consume large amounts of energy (thermal and electrical), as a result of their operation, they produce large amounts of sludge. The anaerobic digestion of these sludges from wastewater treatment produces biogas, which, due to its concentration in methane (CH 4 ), constitutes a biofuel that can be used for energy production. The best ...
