Technology

The Wastewater Association of Rheinfelden-Schwörstadt operates the wastewater treatment facilities in Schwoerstadt and Rheinfelden-Herten, Germany, as well as several rainwater overflow basins. This wastewater treatment facility now satisfies the highest requirements, and with a population of about 47,000, has reached a size that also guarantees sufficient disposal capacity for future generations.

Aeration Blowers

Blower manufacturers are the source for the most accurate information on aeration blower power consumption. This includes the impact of various control technologies on the many types of blowers used for aeration. However, system designers often need to analyze several alternatives, making reliance on input from suppliers inconvenient. An understanding of the principles of operation will also enhance the designer’s ability to assess the data received from various sources.

Industrial Blowers

The 2016 Powder & Bulk Solids Conference & Exhibition was held May 3-5 at the Donald E. Stephens Convention Center at Rosemont, Illinois. Sponsored by the Process Equipment Manufacturers’ Association (PEMA®) and produced by UBM Canon, this event celebrated its’ 40th anniversary as the leading event for the powder industry. Whether for dilute or dense phase pneumatic conveying systems, vacuum, blower and compressed air technologies play an important role in this industry.

Rough Vac

If you want to understand vacuum systems, you have to get out of the ruts, and slog through the mud and bounce over the rocks a bit.  If you’re a “compressed air person”, think outside the box for a few pages with me.  I am going to borrow some terms from the “pump people” to explain how vacuum systems are similar, yet different from compressed air systems. There are several ruts to get out of.  Remembering what changes and what doesn’t, what is controlled, and how to design systems for optimal energy consumption.

Medium/High Vac

When it comes to industrial vacuum pumping applications, whatever material is involved in the process generally gets ingested into the vacuum pump. It’s an inherent issue with any industrial vacuum application, whether it’s simply moisture from inlet air, or something more tangible (i.e. dust, debris, etc.). Harsh vacuum applications — such as those that involve corrosive acids, excessive moisture, or dust particles — can wreak havoc on a vacuum pump’s reliability. This holds especially true for oil-sealed vacuum pumps, rotary vane pumps and piston vacuum pumps.

Measurement

Every municipality and utility is facing the reality of rising energy costs. In 2010, the Town of Billerica, MA, which is located 22 miles northwest of Boston with a population of just under 40,000 residents, engaged Process Energy Services and Woodard & Curran to conduct an energy evaluation of the Town’s Wastewater Treatment Facility (WWTF) and pump station systems sponsored by National Grid. The objective of the evaluation was to provide an overview of each facility system to determine how electrical energy and natural gas were being used at the facility and to identify and develop potential costsaving projects.

Purification

Contamination such as humidity, oxygen or microbiological ingress can impact drug stability throughout the product life cycle. To prevent the risks of stability failure of highly moisture sensitive drugs (e.g. dry powder for inhalation), or the risk of biological ingress of parenteral drugs, highly sensitive integrity tests are required. Most test methods are very challenging in regards to time, effort, complexity or the limitation of sensitivity and detection range.

Vac Generation

Using suction cups and air-driven vacuum pumps is a preferable gripping and handling method of corrugated cardboard materials and boxes in carton-machines like case/carton erectors and rotary cartoners. Robot based applications, like palletizing and de-palletizing, are other examples where the best practice technology for gripping and handling is by suction cups and air-driven vacuum pumps.  
At Scholle IPN, Valley Packline’s engineering experience and JetAir’s drying expertise came together to deliver an automated, energy efficient solution. Ultimately, the new system eliminated 120 man-hours each week dedicated entirely to erecting and washing. The new system can be manned by just one employee as it pulls bins directly off delivery trucks, re-erects, washes, and dries them, and feeds them into the facility for refilling. Throughput at Scholle was improved by the system, while energy costs were kept to a minimum.

This article reviews two common pneumatic conveying system types and the importance for each operating plant to know their design and operating parameters particularly conveying air flow velocity and particle velocity profile.
The integrated process that leads to perfectly finished components begins in the plant’s new material store. “One way we’re staying at the leading edge in our market is by researching the latest innovations and choosing the best machine for each process,” Legere explains. “Our new material store, operational in June 2017, is one example. It combines a physical data base of sheet goods with a robotic arm that handles materials and presents them to a cutting machine for processing. After a few minutes, a finished part emerges. All of this occurs with zero human interaction.”
The capacity and pressure requirements of blowers in a Water Resource Recovery Facility (WRRF) are determined by the aeration system. When systems are manually controlled blowers often operate at constant flow and pressure day in, day out. When the aeration system is automatically controlled to maintain a set dissolved oxygen (DO), however, the blower’s flow and system pressure vary constantly. Understanding these variations will help designers and suppliers optimize blower performance.
In open end pipe line suspension flow, or dilute phase pneumatic conveying, proper particle velocity is critical to continuing productivity and product quality. Until recently, measurement of actual particle velocity within the pipe has not been practical outside the laboratory. The plant operating personnel depend on a much less accurate metric - estimating the conveying air velocity in the pipe and relating that to particle velocity.
Pneumatic conveying systems are widely used in manufacturing plants and process industries. They provide a practical method of bulk-solid material transport. A surprisingly wide variety of powders and granular material can be effectively moved from one location to another within the plant. “Compared with other bulk-solid transport systems, a properly designed pneumatic conveying system affords many advantages".

The 2016 WEFTEC Technical Exhibition and Conference was held September 24-28 in New Orleans, LA. The 2016 event made the list of the top five largest and best-attended events in the conference’s 89-year history. A total of 20,113 registrants and 1,006 exhibitors using a net of 28,000 m2 (301,900 ft2) of space attended WEFTEC. The event featured 130 technical sessions, 29 workshops, 9 facility tours, and numerous other educational and networking events. “The success of this year’s conference reflects WEFTEC’s decades-long tradition of innovation, education, and dedication,” said WEF Executive Director Eileen O’Neill. “From programming to attendance, WEFTEC 2016 was another outstanding chapter in WEFTEC’s history.”
