LITTLE ROCK, AR -- ThermoEnergy Corp. was recently notified the European patent application on the Ammonia Recovery Process (ARP) has been allowed. The claims included in the ARP patent cover key process areas for nitrogen / ammonia removal and control in municipal and industrial wastewater facilities, as well as large pork and dairy confined farming operations.

ARP offers European wastewater treatment plant operators a reliable, low-cost and environmentally responsible method of treating waste streams containing nitrogen in the form of ammonia. Conventional nitrogen treatment technologies necessitate an increase in the overall size of the existing plant. However, most of these plants, once located on the outskirts of town, now find themselves surrounded by commercial and/or residential populations, leaving little or no room for such expansion. This situation is further complicated by increasingly more stringent federal and state clean water regulations, designed to protect human health and the environment.

ARP is especially effective in treating a particularly high concentrated ammonia stream called centrate; a liquid product resulting from dewatering anaerobically digested sewage sludge or animal waste. The recovery and recycling of this ammonia stream not only reduces odors, but eliminates greenhouse gas emissions associated with making new ammonia and treating the waste water. In this manner, every ton of ammonia recovered saves the equivalent of 6 tons of carbon dioxide emissions.

"Europe is a key target market for the Company's wastewater treatment technologies," said Dennis C. Cossey, CEO of ThermoEnergy Corp. "Receiving notice that the ARP patent will issue with substantial claims represents a key milestone in pursuing wastewater opportunities in Europe," added Cossey. As emission limits tighten, wastewater treatment plant operators are looking for ways to both improve plant process performance and meet regulatory requirements at the lowest possible cost. "One of the best ways to achieve this goal is with the ARP process," said Cossey.

While the Company prefers to design, build and operate ARP systems for larger plants, it is in the process of developing a model line for direct sale to smaller municipal and industrial operations. "Although marketing studies have yet to be done for direct sales of the smaller models, industry trends suggest a potential overall annual market of $840MM for the Build/Own/Operate segment by 2010," says Cossey.

LOVELAND, CO -- The Hach Company, the world's largest water and wastewater instrumentation manufacturer, announced that its Homeland Security Technology unit is in the final stages of testing a revolutionary new technology designed to detect terrorist attacks on water distribution systems. Hach has signed a cooperative research and development agreement with the United States Army. The Army's Edgewood Chemical Biological Center (ECBC) and the Corps of Engineer's Construction Engineering Research Laboratory will work with Hach to conduct live-agent testing in secure government laboratories.

"We're in the final stages of verifying the world's first working, reliable real-time detection technology -- capable of discovering adverse attacks and managing the quality of drinking water," commented Jeff Throckmorton, Ph.D., president of Hach Homeland Security Technology. "We're proud to be the first to create this homeland security solution."

Based on the Hach Event Monitor Trigger System, the new technology uses smart instrumentation and advanced interpretation techniques to detect the presence of water contaminants or poisons. A secondary benefit is that it allows drinking water providers to manage water condition and quality on an ongoing basis. Pending successful verification testing and receiving necessary Federal liability protections, the new technology is scheduled for commercial release in 2005.

Under terms of its cooperative research and development agreement, Hach is paying to test its detection/response system at the Aberdeen Proving Ground, one of the few sites in the country where chemical and biological agent testing can legally take place. Aberdeen is part of ECBC. The Army and Hach will construct real-time drinking water systems in secure laboratories using strict environmental and safety procedures.

In addition, the Corps of Engineers is conducting parallel studies with Hach to better understand the dynamics of chemical transport. This information will allow the corps to better understand and monitor water distribution systems and predict the impact of terrorist attacks on those systems.

Hach Company is based in Colorado and Iowa, and is the World's largest water and wastewater instrumentation manufacturer. A part of the Danaher Corporation, Hach manufactures and markets over 3,000 products for water analysis in drinking water, wastewater and industrial applications.

Mr. Sergeant wants to seed an activated sludge plant:

I am part of a team operating a large sludge processing plant. All our plant liquors are treated in a nitrifying membrane bioreactor facility. As part of our contingency plans we are investigating methods to quickly reseed our plant in the event of an emergency.

Therefore I was wondering if anybody could share experiences they may have using pre-prepared bacterial cultures to speed up seeding of activated sludge plants and of contacts with any suppliers especially in the UK or Europe.

It took us 6 weeks to build up the correct amount and species of biomass when we commissioned the plant but we no longer have the luxury of that sort of time scale. (Click here to post a reply)

Peter needs help optimizing MLSS:

I have question about the optimizing MLSS. Our plant wants to figure out an appropriate MLSS for winter operation with nitrification. Do you guys have any suggestions about how to do that? We try to keep our MLSS low enough for the solids handling purpose.  (Click here to post a reply)
