The performance of a modified Anaerobic Baffled Reactor (ABR) treating high strength synthetic wastewater
In the present study the overall performance of a modified Anaerobic Baffled Reactor (ABR) treating high strength synthetic wastewater was first described. The reactor differs from the original ABR as follow: a modified internal lamella separator was positioned at top of each up-flow sections to separate the biogas and liquid to reduce the sludge wash out. The initial organic loading rate was ...

Pendleton wastewater treatment plant biogas application - Case Study
About the Project In 2011, the City began work on a cogeneration facility as part of the upgrades at the Waste Water Treatment Plant. The city was given us the ability to convert solids arriving at the Waste Water Treatment Plant into useful energy and high quality fertilizer. The system was designed to generate about 750,000 kWh per year, which translates into about $50,000 annually in saved ...

Biogas Wastewater Treatment Systems by the Philippine Center for Water and Sanitation: A Community-Managed Potable Water Supply, Sanitation, & Hygiene (CPWASH) Project
The Philippines, like many developing countries, has serious sanitation issues for both their urban and rural citizens. Specifically for rural citizens, data from 2008 estimated that 17% of this population still had no access to improved sanitation, with 14% estimated to be practicing open defecation. With much of the Philippine countryside devoted to agriculture, this is a serious concern, as ...

A combined UASB-MBR with shortcut nitrification-denitrification for energy reduction in wastewater reclamation
Shortcut nitrification has been successfully applied in a laboratory scale nitrification-denitrification process consisting of an up-flow anaerobic sludge blanket (UASB) and an aerobic membrane bioreactor (MBR) in treating synthetic and municipal wastewater to simultaneously remove organic carbon and nitrogen. For the treatment of synthetic wastewater, the combined system exhibited a high TOC ...

RHEINISCHE BIOESTER - Anaerobic wastewater treatment in biodiesel production - Case Study
Some processes during the production of biodiesel, such as glycerine evaporation, fatty acid and methyl ester drying (vapour condensate), generate wastewater which is highly contaminated with organic substances. The most significant substances in the wastewater are glycerine, methanol and free fatty acids. EnviroChemie supplies biological wastewater treatment plants with biogas recovery for the ...

Turning whey into energy
Sweden, Umea. Olof Wallin stared at the official letter on the desk in front of him and thought hard. Under his management the dairy in Norrmejerier produced more milk products every year, cheese production too was on the rise, and now this. The public canalization could no longer handle the whey which was a waste product of the daily cheese production and disposed of with the dairy’s ...

Norrmejerier dairies - Use of biological wastewater treatment to generate energy, preserve resources and lower operating costs - Case Study
In June 2005 at the Norrmejerier dairies in Umeå (Sweden), the Swedish environment minister, Lena Sommestad, inaugurated the company’ s first Biomar® plant for the biological treatment of wastewater. The project was supported by the EU. The organic substances left behind by rinsing during milk processing and found in whey and whey permeates are acidified, hydrolysed and ...

Inter-stage thermophilic aerobic digestion may increase organic matter removal from wastewater sludge without decreasing biogas production
Combining aerobic and anaerobic digestion in a two-stage system can improve the degradation of wastewater sludge over the use of either technology alone. But use of aerobic digestion as a pre-treatment before anaerobic digestion generally reduces methane production due to loss of substrate through oxidation. An inter-stage configuration may avoid this reduction in methane production. Here, we ...

Use of Waste-to-Energy Sludge Growing in Europe
This byproduct of anaerobic digestion is fertilizing fields and helping divert waste from landfills Anaerobic digestion (AD) is an important waste-to-energy technology that harvests energy — in the form of biogas — from organic pollutants in wastewater and solid waste. Anaerobic digestion is ideal for challenging wastewater streams that might cause significant public health risk if ...

Life cycle assessment of introducing an anaerobic digester in a municipal wastewater treatment plant in Spain
Anaerobic digestion (AD) is being established as a standard technology to recover some of the energy contained in the sludge in wastewater treatment plants (WWTPs) as biogas, allowing an economy in electricity and heating and a decrease in climate gas emission. The purpose of this study was to quantify the contributions to the total environmental impact of the plant using life cycle ...

Sulfide removal from industrial wastewaters by lithotrophic denitrification using nitrate as an electron acceptor
Sulfide is present in wastewaters as well as in biogas and can be removed by several physicochemical and biotechnological processes. Nitrate is a potential electron acceptor, readily available in most wastewater treatment plants and it can replace oxygen under anoxic conditions. A lab-scale reactor was operated for treatment of sulfide containing wastewater with nitrate as an electron acceptor ...

Quantification of dissolved methane in UASB reactors treating domestic wastewater under different operating conditions
This paper aimed at measuring the concentration of methane dissolved in effluents from different UASB reactors (pilot-, demo- and full-scale) treating domestic wastewater, in order to calculate the degree of saturation of such greenhouse gas and evaluate the losses of energetic potential in such systems. The results showed that methane saturation degrees, calculated according to Henry's law, ...

Potential contribution of the wastewater sector to energy supply
The biological treatment of wastewater could yield high energy fuels such as methane and alcohols, however most conventional treatment systems do not recover this energy potential. With a simple model of the energy yields of various wastewater treatment technologies it is possible to demonstrate how minor shifts in technology selection can lead the industry from being identified as predominantly ...
