Don’t Settle for Less than the Best

The best efficiency. The quietest operation. The highest savings. Energy is the single highest operating cost in a wastewater treatment plant and 60% of a plant’s energy costs are spent on aeration. At Kaeser, we’ve been providing efficient aeration solutions for many years

Kaeser’s Sigma screw blower packages are 35% more efficient than conventional blower designs. In addition to exceptional efficiency, our screw blower packages are designed and built from the ground up for reliability and service accessibility.  They come complete with motors, starters/drives, silencers, an onboard controller, and a full complement of sensors to save you time and money on design and installation costs

I had a very interesting meeting with Julie Gass and Patrick Dunlap, this summer at Black  & Veatch’s offices in Kansas City. In a fascinating conversation, we reviewed a host of technologies ranging from panel diffusers to aeration blowers. Somewhere in the middle we did a long, challenging, review  of DO Control,  Most Open Valve Control, Flow Control and even Ammonia Control strategies.  Leading off this Issue, we hope you learn as much as I did and enjoy “Part 1: The Demand Side – Diffusers  and  DO Control”.

The wastewater treatment plant in the Town of Hurlock, Maryland provides service to approximately 2,100 residences.  However, the majority of the water treated comes from a nearby poultry processing plant, giving the plant influent a high organic content. That is why the Town

of Hurlock replaced  its two million-gallon-per-day  (MGD) lagoon plant with a 1.65 MGD four- stage activated sludge facility ten years ago. Paul Petersen, from Atlas Copco, shares this story with us about how they reconfigured their aeration blowers to reduce energy consumption.

Tim Hilgart,  from  Howden  Roots,  writes  about  how their  DO Control  system  was  able to optimize the 180 MGD challenge at the Bird Island wastewater treatment plant in Buffalo, N.Y.. This article demonstrates expertise in Most Open Valve Control logic, an expertise for which there is growing demand. The project delivered an annual savings of 3.8 million kWh equaling

$۳۴۵,۰۰۰ with an excellent ROI assisted  by a NYSERDA rebate  covering fifty percent  of the cost.

Tom Jenkins  is the President of JenTech and is an expert consultant on aeration blowers. He also explains things in a way I can understand!  For those of you in the field, he has provided a very useful article (one for the files) with the steps to calculate  the air flow rate, how

to determine the best strategy for blower turndown, and the calculations  to establish the required discharge pressure.

Last but not least, I hope you enjoy our Show Report on blower and vacuum technologies at AISTech 2016. Steel degassing processes are switching to mechanical  vacuum systems, providing up to 97% energy reductions according  to Edwards and Oerlikon Leybold booth personnel.  Blow-off air processes are also being optimized with dedicated blower and custom air knife technologies and we enjoyed visiting with Sonic Air Systems and Silvent InTech. Our technologies really are helping the steel industry be more efficient.

APG-Neuros Celebrates 1000th   Turbo Blower

Delivery Milestone

It is truly a very proud  moment  for APG-Neuros, manufacturer  of high efficiency turbo blowers, to highlight an important milestone this year with the achievement of the 1000th turbo blower delivery to the City

of South San Francisco-San  Bruno Water Quality Control Plant, United States. This accomplishment demonstrates our customers’ strong confidence in our company, our team, the air bearing technology, our NX series  high efficiency Turbo Blower product and the benefits it brings them.

The operations  team at the city of South San Francisco are very pleased with the innovative product and support we received over the past four years  from APG-Neuros,” said Mr. Brian Schumacker, the Plant Superintendent  for the South San Francisco-San Bruno Water Quality Control Plant.

Year after year, APG-Neuros is experiencing success and growth with its High Efficiency High Speed  Turbo Blower.  APG-Neuros has built

a state of the art Assembly and Test facility in the U.S., located in Plattsburgh NY, and a well-established  head-office in Montreal with Administration, Engineering, Sales and Support network personnel. APG-Neuros also  built  a strong factory service team located within close proximity of customers across  North America and in Europe that is dedicated to support the customers operating its Turbo Blower product line. Its network of direct  sales and support staff are also assisted by sales representatives and a network  of factory trained service technicians and control engineers located strategically in the proximity  of its customers.

APG-Neuros  CEO & President Mr. Omar Hammoud said, “We thank the City of San Francisco-San  Bruno Water Quality Control Plant for their loyalty and the confidence they place in us. The repeat sales and the appreciation we receive from our customers give us encouragement to continue to work hard and strive to provide the wastewater treatment community with more product innovations and outstanding service.”

bearing Turbo Blower and are selecting our product as their first choice. We are pleased with the positive impact our innovations are having on our customers and we will continue to do so in the future.”

APG-Neuros Celebrated the 1000th  Turbo Blower Delivery

It all began in 2005 with only one person, Omar Hammoud, and has grown to a present total of 72 employees. Today, APG-Neuros

has over 1,050 turbo blowers installed with over 250 customers in North America and the European Union; mainly in municipal and industrial wastewater treatment plants. APG-Neuros developed the Smart Connected

Product solution, Filter Upgrades, Installation Design upgrades, Software upgrades and flexible Service Plans that address the customers’ emerging requirements and significantly increase the operational flexibility availability  level of its product. In 2013 and

Mr. Hammoud continued,  “We continue

to be successful with our repeat customers; we are also seeing many new small and large municipalities  across  North America and Europe adopting the technology of the air

CAGI Blower Section Announces

New BL300 Blower Data Sheets

The Compressed  Air and Gas Institute’s (CAGI) Blower Section has announced plans to make Blower Package Data Sheets available in the near future. The sheets are based on testing conducted according to the CAGI/PNEUROP

BL 300 standard, Performance Test Code for Electric Driven Low Pressure Air Compressor Packages.  BL300 is a new joint standard developed through cooperative work by US

and European trade associations. The CAGI/ PNEUROP standard is designed to enable the collection and presentation of comprehensive and consistent performance data independent of blower technology.

In addition to the BL300 document, CAGI has established a standard means for manufacturers to report their machines’ performance and efficiency in the form of data sheets. Blower Section Chair, John Conover, said “Members have committed to publishing data sheets for 75 hp, 100 hp, and 150 hp models in the second half of 2016.”

The data sheets will cover fixed and variable speed drive units for both positive displacement and dynamic blower technologies. These

data sheets will be accessible  via a link on the  CAGI website under the “Performance Verification” tab.

The joint standard enables the fair comparison of package performance on a level playing

field. “BL 300 is a standard means of evaluating blowers which provides users with complete package performance data that was just not available before,” according to Chris Johnson, Executive Director of CAGI. “It includes a reference to ISO 1217, the standard for testing positive displacement blowers, and to BL 5389, the standard for testing turbo blowers.”

The development  of BL 300 was initiated at the request of the wastewater treatment industry; however, the standard was expanded to make

it suitable for use with blowers in general industry and other applications. When blower packages are compared  using BL 300 results, plant managers, engineers, and technical advisors can use CAGI datasheets to access the following performance information:
