Pulsar Process Measurement (UK) have launched Flow Pulse, a compact and cost-effective pipe flow monitor that promises exceptional repeatability, accuracy and simple installation with no down time. Flow Pulse is perfect for monitoring flow rate in fluid distribution systems, for pump efficiency checks, in process plant or sewage pumping stations.
Flow Pulse (patent pending) is a leap forward in flow measurement and in ease of installation – no need to break into a pipe, or to get any engineering involved, just clamp a small sensor to the outside of a pipe and immediately get a reliable, repeatable flow measurement (tools required = one screwdriver). Virtually no installation costs, no interruption to service, clean and simple.
Flow Pulse uses a novel spread spectrum analysis technique never before used in flow monitoring. It introduces a radical new Digital Signal Processing approach for exceptional repeatability:
Ultrasound is fired through the pipe wall at 90 degrees to the flow via a tangentially mounted high-output ceramic, then refracted at angles across the axis of the flow and subsequently reflected from bubbles, particles and vortices in all directions and at a wide range of frequencies. The wide, refracted, ultrasonic beam maximises the ultrasound energy that could be captured from flowing particles. These multiple reflections are received back into the unit via a second crystal.
The mass of data generated is analysed using Flow Pulse’s Refracted Spread Spectrum Analysis (RSSA) digital signal processing platform to derive flow information. RSSA analyses and integrates the received signals over a wide frequency range, then slices them for real-time analysis and flow rate calculation.

Methanobacterium thermoautotrophicum has been reported to require nickel for growth and to contain high concentrations of a nickel tetrapyrrole designated factor F430. In this communication it is shown that all methanogenic bacteria investigated incorporated nickel during growth and also synthesized factor F430. This was also true for Methanobrevibacter smithii, which is dependent on acetate as a carbon source, and for Methanosarcina barkeri growing on acetate or methanol as energy sources. Other bacteria, including Acetobacterium woodii and Clostridium thermoaceticum, contained no factor F430. It is further shown that two yellow nickel-containing degradation products were formed from factor F430 when heated at pH 7. This finding explains why several forms of factor F430 were found in methanogenic bacteria when a heat step was employed in the purification procedure.

Methanol is an important anaerobic substrate in industrial wastewater treatment and the natural environment. Previous studies indicate that cobalt greatly stimulates methane formation during anaerobic treatment of methanolic wastewaters. To evaluate the effect of cobalt in a mixed culture, a sludge with low background levels of cobalt was cultivated in an upflow anaerobic sludge blanket reactor. Specific inhibitors in batch assays were then utilized to study the effect of cobalt on the growth rate and activity of different microorganisms involved in the anaerobic degradation of methanol. Only methylotrophic methanogens and acetogens were stimulated by cobalt additions, while the other trophic groups utilizing downstream intermediates, H2-CO2 or acetate, were largely unaffected. The optimal concentration of cobalt for the growth and activity of methanol-utilizing methanogens and acetogens was 0.05 mg liter-1. The higher requirement of cobalt is presumably due to the previously reported production of unique corrinoid-containing enzymes (or coenzymes) by direct utilizers of methanol. This distinctly high requirement of cobalt by methylotrophs should be considered during methanolic wastewater treatment. Methylotroph methanogens presented a 60-fold-higher affinity for methanol than acetogens. This result in combination with the fact that acetogens grow slightly faster than methanogens under optimal cobalt conditions indicates that acetogens can outcompete methanogens only when reactor methanol and cobalt concentrations are high, provided enough inorganic carbon is available.

JBS SA (JBSS3), the world’s largest beef producer, is set to post the highest quarterly profit since 2008 as Brazilian meatpackers are shielded from surging grain and cattle prices that eroded the margins of global peers.
Third-quarter net income will be 331.8 million reais ($164 million), compared with a year-earlier loss of 67.5 million, according to the average of four analyst estimates compiled by Bloomberg. JBS’s 19 percent return in the past three months makes it the world’s third-best performing meatpacking stock, after Barretos, Brazil-based Minerva SA and Marfrig Alimentos SA (MRFG3), which gained 44 percent and 38 percent, respectively.

Poultry Industry Provides 1,337,030 Jobs and $265.6 Billion in Economic Impact to U.S. Economy The U.S. Poultry & Egg Association, National Chicken Council, National Turkey Federation, and United Egg Producers have made available a new economic impact study and four new websites that highlight the positive impact the poultry industry has on jobs, wages, and federal and state revenue in the United States. A dynamic and integral part of the national economy, the poultry industry collectively provides 1,337,030 jobs, $63 billion in wages, $265.6 billion in total economic activity, and $23.4 billion in government revenue.The study breaks down poultry into three subcategories: chicken, turkey and eggs. http://www.uspoultry.org/
The International Poultry Expo has announced a new featured educational program at their 2012 Expo titled International Rendering Symposium: Focus on Quality.
“Encompassing safety and quality control practices serve as the foundation to the production of a quality product,” said Dr. David Meeker, Vice President of Scientific Services for the National Renderers Association. “Rendered byproducts are an essential aspect to the poultry industry.”
Hydro Solutions’ customized REACT-OX program can be an essential component of safe and efficient rendering production, including poultry, beef, and pork. REACT-OX works within your air scrubber to remove odorous gases, VOCs, and odor-causing compounds from the air stream.
We at Hydro Solutions encourage attendance at this symposium, which is set for Thursday and Friday, January 26-27, 2012 at the Georgia World Congress Center in Atlanta, GA. All registered Expo attendees are eligible to attend the International Rendering Symposium for an additional $150.
More details, including an agenda and how to register, can be found here.

U.S. Poultry & Egg Association has announced that they will continue accepting applications for the 2012 Clean Water Awards until December 15, 2011.
There are two categories for the award. One category is for full treatment facilities, which are those facilities that fully reclaim their wastewater prior to discharge into receiving water or a final land application system. The other category is for pretreatment facilities, which are those facilities that discharge pretreated effluent to publicly-owned full treatment facilities.
The 2012 winners will be announced at USPOULTRY’s Environmental Management Seminar, to be held March 7-8 in Nashville.
We at Hydro Solutions join in congratulating the 2011 Clean Water Award winners: Perdue Farms in Perry, GA, for full treatment; Keystone Foods LLC in Gadsden, AL, for pretreatment; and American Proteins in Cuthbert, GA, which received honorable mention in the full treatment category.
