The laminar/turbulent transition in a sludge pipeline
Globally, wastewater treatment plants are under pressure to handle high concentration sludge in a sludge treatment line. Unawareness of the non-Newtonian behaviour of the thickened sludge has the potential to cause unexpected problems when the fluid behaviour changes from turbulent to laminar flow. In this study, sludge apparent viscosity was plotted as a function of total suspended solids ...

Energy at Wastewater Treatment Plants - A Short Primer
On the topic of wastewater, most people are understandably of the “flush and forget” variety. But today’s wastewaster professionals recognize that in the long term, our approach to sewage treatment needs to be less about “processing” wastewater, and more about “recovery” of limited resources such as water and energy from the incoming waste. ...

Celdar Technology - N Compounds Speciation Removal in Biogas Wastewater - Case Study
To approach a complex wastewater treatment plant, the customer asked us to evaluate the ELECTROCOAGULATION SYSTEM for the removal of NITROGEN COMPOUNDS and to be able to drain the treated water into the sewer system. Another option required was the ZERO LIQUID DISCHARGE and therefore the possibility of water recycling with the least amount of consumption possible. This option is possible using an ...

Behaviour of Microbial Fuel Cell in a start-up phase
A Single-Chamber Microbial Fuel Cell (SCMFC) was constructed and run in a sequential feed-and-draw cycle operation. Anaerobic mixed bacterial culture and wastewater obtained from a local municipal wastewater treatment plant were used as biocatalysts and media, respectively. The SCMFC behaviour in a start-up phase was examined using the electrical potential (voltage) profiles, and further ...

Biopetrol Rostock - Wastewater treatment for emulsion-containing wastewater from bio-diesel production - Case Study
BIOPETROL Rostock GmbH is owned by the Swiss BIOPETROL INDUSTRIES AG in Zug, and operates a bio-diesel plant in Rostock with an output of 150,000 t/a of bio-diesel and 24,000 t/a of crude glycerine. The emulsion-containing wastewater created during operation was disposed of externally. A more extensive wastewater treatment plant was required to facilitate the discharge of the wastewater into the ...

The Benefits of Biogas Conditioning
Abstract Anaerobic digestion is quickly becoming the choice technology for sewage sludge treatment at wastewater treatment plants, as the methane rich biogas produced is a valuable resource which can be used to generate electricity. In the oxygen restricted environment, a natural by-product of the anaerobic process is hydrogen sulfide, a harmful contaminant. Also present in the biogas are ...

Waternet Amsterdam: First biomethane injected in national grid
Milestone achieved at Waternet Asset Management biomethane project The wastewater treatment plant of Waterschap Amstel, Gooi & Vecht, produces biogas. This biogas is upgraded to biomethane using the DMT biogas upgrading technology. The first cubic meter of biomethane was injected into the national grid on March 19th. By achieving this important milestone, the project enters the third and ...

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 ...

Energy benchmarking of South Australian WWTPs
Optimising the energy consumption and energy generation of wastewater treatment plants (WWTPs) is a topic with increasing importance for water utilities in times of rising energy costs and pressures to reduce greenhouse gas (GHG) emissions. Assessing the energy efficiency and energy optimisation of a WWTP are difficult tasks as most plants vary greatly in size, process layout and other ...

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 ...

Project - Biogas Desulfurization at ETAR do Norte (Portugal)
The Wastewater Treatment Plant (ETAR) do Norte is one of the largest in the central region of Portugal, serving several municipalities. The infrastructure is located in the area of Coimbra, Leiria, occupying 6 hectares of land; it receives effluents from about 250,000 inhabitants of several municipalities. It has the capacity to treat some 38,000 m3 of wastewater daily, of which 77% is domestic, ...

St. Cloud Duel Fuel Engine, USA - Case Study
In 2016, St. Cloud Wastewater Treatment Facility selected GE Jenbacher as the dual fuel engine of choice for their new renewable energy plant. For most cities, wastewater and drinking water treatment plants are major energy hogs so when St. Cloud was looking for ways to reduce its utility bills, it made sense to look at the sprawling wastewater treatment plant on the city’s south side. The ...

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,” ...

Desulfurization and reduction of siloxanes in biogas
Reducing the carbon footprint of our society is essential. This can be achieved by capturing and confining anthropogenic CO2 emissions, as well as by replacing fossil fuels with renewable fuels. MCFCs (Molten Carbonate Fuel Cells) are the only ones capable of doing both. Thanks to their principle of operation, CO2 can be extracted from a gas stream on the cathode side and fuels such as biogas ...
