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 ...

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 ...

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 ...

A critical review of experimental and predicted methane generation from anaerobic codigestion
Anaerobic digestion is increasingly being considered as a treatment option for an extensive range of waste biomass, due to the potential for energy recovery, in the form of methane production, and lower sludge volumes relative to aerobic treatment processes. Furthermore, when two substrates are codigested (i.e. digested together), added benefits are foreseeable, such as increased methane ...

Anaerobic treatment of a medium strength industrial wastewater at low-temperature and short hydraulic retention time: a pilot-scale experience
The aim of this work was to evaluate the performance of a pilot-scale upflow anaerobic sludge blanket (UASB) reactor during the treatment of cereal-processing industry wastewater under low-temperature conditions (17 °C) for more than 300 days. The applied organic loading rate (OLRappl) was gradually increased from 4 to 6 and 8 kg CODsol/m3d by increasing the influent soluble chemical oxygen ...

Effects of influent fractionation, kinetics, stoichiometry and mass transfer on CH4, H2 and CO2 production for (plant-wide) modeling of anaerobic digesters
This paper examines the importance of influent fractionation, kinetic, stoichiometric and mass transfer parameter uncertainties when modeling biogas production in wastewater treatment plants. The anaerobic digestion model no. 1 implemented in the plant-wide context provided by the benchmark simulation model no. 2 is used to quantify the generation of CH4, H2 and CO2. A comprehensive global ...

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 ...

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 ...

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 ...

Make it stick!
The Water and Sewerage Works in Oslo, Norway was recently awarded the Global Award in Communications by the International Water Association for their information campaign about the use of biogas for city buses. The campaign’s goals to be seen and to be remembered had two objectives: 1. Inform the public about biogas. It is a by-product from wastewater that is environmentally-friendly ...

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 ...

Wastewater Pre-Treatment for the food industry (vinegar and dressings)
Description of the plant Highly polluted wastewater arises from the production of high-quality vinegar, delicatessen and mustard products. Most of the COD load here is formed by lipophil substances which have to be decreased before to municipal sewer net. Peaks of load and flow are buffered in a mixing and balancing reactor to achieve an homogenised flow to the chemical-physical pre-treatment ...
