MICROBE-LIFT Technology Improves Efficiency of Anaerobic Digesters in Columbia - Preventing Costly Expansion - BIO-GAS
Location: Empresas Publicas, Columbia Background: Ecological Laboratories Inc. was contacted by Empresas Publicas to determine if bioaugmentation with MICROBE-LIFT® technology could assist in the operation of their anaerobic digesters. The facility consisted of two anaerobic digesters of 7,900 m3 each. The average flow rate was 1.8 m3 per second giving an average hydraulic retention time ...

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 ...

HRS helps AD plant tap into additional heat from existing CHP
Operators of anaerobic digestion (AD) plants know how important it is to optimise energy use across all stages of the process. That is why many recapture as much heat as possible for reuse elsewhere, including from the hot exhaust gases generated by the combined heat and power (CHP) engines which turn the biogas from the AD plant into useful heat and electricity. Heat exchangers used for exhaust ...

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,” ...

Solutions for sludge and biomass drying
Sludge is mostly water with some amounts of solid material removed from liquid sewage. Primary sludge includes settleable solids removed during primary treatment in primary clarifiers. Secondary sludge is sludge separated in secondary clarifiers that are used in secondary treatment bioreactors or processes using inorganic oxidizing agents. In intensive sewage treatment processes, the sludge ...

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 ...

Modified ADM1 for high-rate anaerobic co-digestion of thermally pre-treated brewery surplus yeast wastewater
Co-digestion of surplus yeast with brewery wastewater is a potentially economical method for recovering energy, in the form of biogas, from this difficult to dispose of by-product. In this work a modified version of the ADM1 (Anaerobic Digestion Model No. 1) was calibrated for an anaerobic digester fed with thermally pre-treated brewery yeast surplus wastewater. The model could predict ...

Assessing the Market for Anaerobic Digestion
The anaerobic digestion (AD) industry is growing rapidly. In the UK there are over 215 anaerobic digesters in operation and more than 100 in planning. Understanding how a market will develop is crucial to any successful venture. A client came to us looking to improve their understanding of the current status and future potential of the AD market in the UK and Ireland. In order to progress ...

Generation using gas-fuelled engines in South Africa – an overview
Most gas engines are Otto cycle spark ignition internal combustion reciprocating engines using natural gas as the primary fuel. Smaller models utilise stochiometric combustion while the larger engines are lean burn engines with pre-chamber ignition systems. The engines are coupled with packaged generator sets, cogeneration and, even, trigeneration units to optimise energy utilisation in the fuel ...
