WAITSFIELD, VT -- The New York Power Authority (NYPA) has commissioned Northern Power Systems, a subsidiary of Distributed Energy Systems Corp, to design and install a 165- kilowatt power generation system for the New York City Department of Environmental Protection (NYCDEP) at its Owl's Head Wastewater Treatment Facility in Brooklyn, New York.

The water treatment site will be the first wastewater facility in the country to install multiple Stirling engines to generate its own electricity. Manufactured by STM Power, the three 55-kilowatt Stirling external combustion engines are designed to burn anaerobic digester gas, a byproduct of the wastewater treatment process that is currently "flared" into the atmosphere.

By burning digester methane, the Owl's Head facility will experience several benefits. First, by converting a waste byproduct of its process into a free, renewable fuel source, the facility is expected to lower its energy costs. Second, the system will create an environmental benefit by providing an overall net reduction of up to 765 tons of CO2 per year as well as significant reductions in NOx and SO2 emissions. Finally, by generating its electricity onsite, the facility will help reduce congestion on the area's over-stressed utility grid.

Because it is designed to capture waste fuel at the site and generate electricity while simultaneously reducing emissions, the system qualifies as a renewable power source. The New York State Energy Research and Development Authority (NYSERDA) is supporting the project with a grant of $250,000 in recognition of the energy and environmental benefits that the system is expected to deliver.

Drawing from experience with other wastewater treatment facilities, Northern Power designed an optimal technology solution for the Owl's Head site. Because Stirling external combustion engines require less frequent maintenance than microturbine or reciprocating engine technology, the facility is expected to experience increased uptime and reduced parasitic system loads. The engines also offer the potential for reduced gas cleanup and less gas compression than other technologies, which can reduce installation costs.

The project is also part of a larger initiative on the part of the City of New York to voluntarily increase renewable energy capacity in an effort to reduce overall greenhouse gas emissions.

"This project demonstrates a new technology option for wastewater treatment plants, making it an exciting development not only for Owl's Head, but for treatment plants throughout the country," stated Jim Stover, Project Manager at Northern Power. "More and more businesses and public entities are taking advantage of their existing waste streams to create green energy; systems like this one can allow plants to reduce costs and achieve energy objectives simultaneously."

Northern Power Systems designs, builds and installs reliable power solutions for commercial, industrial, government, and military customers. The company also conducts research and development in the areas of renewable energy, distributed generation and hydrogen technology.

Biosolids Research : Request For Proposal Released

Alexandria, VA -- The Water Environment Research Foundation (WERF) is soliciting proposals from researchers who can help develop a protocol that will allow for collecting, acting on, and maintaining data on reports of alleged health symptoms by people living near municipal wastewater treatment biosolids land application sites.

This research responds to a July 2002 report from the National Research Council (NRC) of the National Academy of Sciences. Although the NRC report found no documented scientific evidence that the part 503 rules have failed to protect public health, it did recommend that U.S. EPA update the scientific basis of regulations governing biosolids, improve knowledge of chemicals and pathogens, and evaluate concerns about health effects and exposure. WERF will play a role in helping to fill these scientific gaps and will provide its findings to U.S. EPA.

The WERF funding for Phase 1 of this program is $150,000. The complete research program includes the development of a protocol (Phase 1), the pilot testing and refinement of the protocol (Phase 2), and a methodology for its implementation and use by the appropriate agencies (Phase 3). The funding amounts for Phases 2 and 3 will be established while Phase 1 is underway.

WERF has committed nearly $1 million in funding for research related to biosolids this year; an additional $1.5 million in funding has been committed by WERF subscribers and other organizations over the next five years.

This project, along with two other projects WERF has started work on, was ranked highly at the 2003 Biosolids Research Summit, during which a group of nearly 75 individuals representing agencies, conservation groups, wastewater facilities, academia, and citizens identified their most pressing research needs regarding land application of biosolids. Overall, WERF's biosolids research is valued at nearly $20 million.

Victor, NY -- Ecovation, Inc., a leading provider of customized wastewater treatment solutions, today announced it has acquired the business and assets of Krofta Technologies Corp. Based in Dalton, Massachusetts, Krofta is a worldwide leader in high-performance dissolved air flotation (DAF) and integrated DAF and filtration (DAFF) water and wastewater treatment systems. Krofta will operate as a wholly-owned subsidiary of Ecovation, expanding the company’s offerings beyond its cornerstone anaerobic biological treatment product, Mobilized Film Technology (MFTSM).

“This acquisition adds technical strength in our quest to provide more full-service solutions to our clients,” said Ecovation’s chairman and chief executive officer, Diane C. Creel. “Krofta is the perfect fit because their technologies are extremely compatible with our patented MFT.”

The companies’ technologies can be used together to provide complete treatment for a large number of wastewaters from the food and beverage and allied industries. Krofta’s equipment provides front-end removal of suspended solids, and fats, oils and grease, while Ecovation’s MFT process is used to remove dissolved organics from the wastewater. In addition, Krofta’s equipment can be installed as post treatment for the MFT to further polish the wastewater for potential reuse. Clients also will benefit from space savings and the scalability the combined technologies provide.

“The market is already taking notice of the benefits and reliability of our combined capabilities,” said Mike Noyes, president of Krofta. “Overall, we’re increasing our ability to tailor solutions for a very diverse set of clients. Together, we’ll continue to expand our offerings and develop new treatment solutions and patents for related technologies.

Krofta's patented advanced dissolved air flotation technologies are used to treat industrial and municipal process water and wastewater. More than 3,000 Krofta designed units have been successfully installed around the world treating wastewater from food, dairy, pulp and paper, municipal, automotive, resort, refinery, tannery and petrochemical operations.

Mr. Hoffmaster wants an alternative to evaporation beds:

I am looking for alternative methods of evaporation technology. And any standards to set up an area for evaporation beds. I am dealing with 85,000 gpd of flow with a TDS of 5700 mg/L.

I was thinking reed beds but have been told the average life is only about 10 years. My client had asked about covered evaporation beds, but I have no knowledge of these or design specs.  (Click here to post a reply)

Any help would be great,

Mr. Vallentgoed needs help with floating sludge:

I am suffering with floating sludge on the 2nd clarifier. Reading former messages on this topic in this forum could not help me. So here is the situation:

We are treating a mix of glycol and formic acid in 750 m3 reactor, 8 meters high. Air is used to an internal sludge recycle system on the bottom of this vessel. Between the reactor and clarifier a cyclone system is placed for degassing of the mixed liquor. The clarifier shows very often floating sludge without visible bubbles. There is no denitrification as we measure no nitrate outlet reactor. The formation of the layer is higher incase the COD load increases.

The pH outlet is 7.5. There are carbonates in the influent (1.5 g/ltr). If I take a sample of the mixed liquor it directly floats completely in a 1 liter cylinder.  Very fine bubbles can be observed. I think it is CO2. I must say the sludge age is poor controlled.

I have 2 measurements in my mind: increase the pH in the reactor and strip more CO2 from the reactor by putting more air on it. What do you suggest?  Thank you very much in advance for your answer.  (Click here to post a reply)
