  • The whey to renewable energy

    When Tom Wilson with the Pennsylvania State University Cooperative Extension set out to study the feasibility of a community-based anaerobic digester in Mercer County, he initially analyzed processing manure collected from area dairies and food wastes gathered from the local college, nearby prisons and industrial food processors. But the economics of transporting the materials just did not make ...

  • Biogas production and potential from U.S. Wastewater Treatment

    How many wastewater treatment plants (WWTPs) have anaerobic digestion? How many are utilizing the biogas? What percentage of these facilities are feeding additional substrates into their digesters? How is the biogas being used — is it flared, used to drive process machinery, heat the digester, or injected into a natural gas pipeline? These are some of the questions asked of the ...

  • How big is the distributed energy opportunity for water and wastewater utilities?

    Energy costs for water utilities are large, and growing Energy is a significant cost for many water utilities, and costs are growing as more energy-intensive forms of water supply, including desalination, are being used. Energy is typically the second-largest utility budget item in developed countries, after labour. In many developing countries, energy can account for 70% or even more, of ...

    Untitled Document ABSTRACT 1. One of the most important environmental problems faced by the world is management of wastes. Industrial processes create a variety ...


  • Phosphorus and Heavy Metal Extraction from Wastewater Treatment Plant Sludges Using Microwaves for Generation of Exceptional Quality Biosolids

    ABSTRACTThe objective of this study was to evaluate how much phosphorus and metals in sludge can be released into solution by microwave irradiation when applied to sludge prior to anaerobic digestion, and to determine the effectiveness of subsequent lime precipitation. For thickened sludge, the fraction of phosphorus in the soluble form increased to 23%~28% while for unthickened sludge, to ...

  • Microalgae as a sustainable alternative for wastewater treatment

    Thanks to the threats posed to human health and the environment, and the economic costs of its treatment, wastewater from domestic, industrial and agricultural processes has been considered a serious problem for a long time. However, a paradigm shift in the past few years has led to a new concept of wastewater, not as a problem but as a source of energy and other precious resources, including ...

  • Electrocoagulation Wastewater Treatment: Specialized Technology to meet the needs of food & beverage wastewater

    The effects of water scarcity and stricter environmental regulations placed on water usage are increasing the cost of using freshwater globally. The consequences of these increasing costs on food and beverage companies are twofold, since the companies are charged for both the water that they utilize in their processes and on their wastewater discharge. Additionally, the food and beverage industry ...

  • Bolivar wastewater treatment plant cogeneration facility to be Installed by Clarke Energy - Case Study

    The Bolivar Wastewater Treatment Plant (WWTP) is the largest wastewater treatment plant in the Adelaide region, processing almost 70% of Adelaide’s metropolitan wastewater. The South Australian Government has approved a $25.8 ...

  • National brewery benefits from biogas

    Anheuser-Busch has installed anaerobic digestion systems at 10 of its 12 large breweries in the U.S., with an 11th system in design. Primary drivers are cost-avoidance for wastewater treatment fees and fossil fuel purchases. ANHEUSER-BUSCH, owner of 12 large breweries in the U.S., has committed to reduce its greenhouse gas emissions 5 percent from 2005 levels by 2010. The company is well ...

  • Climate change mitigation by recovery of energy from the water cycle: a new challenge for water management

    Waternet is responsible for drinking water treatment and distribution, wastewater collection and treatment, and surface water management and control (quality and quantity) in and around Amsterdam. Waternet has the ambition to operate climate neutral in 2020. To realise this ambition, measures are required to compensate for the emission of 53,000 ton CO2-eq/year. Energy recovery from the water ...

  • Promoting Wastewater Reclamation and Reuse in the Kingdom of Saudi Arabia

    Water reclamation and reuse has become an important worldwide total water management topic as the limitations of freshwater resources have come into sharp focus. In the Kingdom of Saudi Arabia (KSA), potable water is produced from either non- or very slowly renewable water resources such as groundwater, or capital- and energy-intensive seawater desalination. The KSA also lacks sufficient water ...

  • Biomethane production at Ontario wastewater treatment plant

    The City of Hamilton is purifying biogas and injecting it into the grid, while continuing to generate power and recover heat from its CHP system. Hamilton, Ontario, has long been a leader in producing biogas from its sewage and storm water wastes. Half a century ago, the city of 520,000 began processing sludge from its sprawling Woodward Avenue Wastewater Treatment Plant through anaerobic ...

  • Closing the last Energy Leak

    The heat contained in wastewater is one of the last major untapped resources in the field of renewable energies, despite the fact that it may some day provide some 20% of the heating energy we need. This huge potential has been addressed by a Swiss engineering office, Rabtherm AG, which now supplies patented technology for generating energy from wastewater, used for heating or cooling buildings. ...

  • Water recovery from sewage using forward osmosis

    This research is part of the Sewer Mining project aimed at developing a new technological concept by extracting water from sewage by means of forward osmosis (FO). FO, in combination with a reconcentration system, e.g. reverse osmosis (RO) is used to recover high-quality water. Furthermore, the subsequent concentrated sewage (containing an inherent energy content) can be converted into a ...

  • Digestion of wastewater pond microalgae and potential inhibition by alum and ammoniacal-N

    Algae are produced in considerable quantities in oxidation ponds, and may negatively affect receiving waters when discharged at high concentration. Thus in some instances they require removal prior to effluent discharge, which may be enhanced using flocculants such as alum. Harvested algal biomass could be anaerobically digested to methane for use as a renewable energy source, however, alum, has ...
