Industrial Utility Efficiency


The 2019 WEFTEC Technical Exhibition and Conference was held September 23-25 at McCormick Place in Chicago. The event featured 148 technical sessions, 27 workshops, 16 mobile sessions, seven local facility tours and 1,000+ exhibitors.  Both Blower & Vacuum Best Practices and Compressed Air Best Practices® Magazines were pleased to be in the literature bins at the 2019 WEFTEC!

Custom Blower and Air Knife Bin Drying Solution Reduces Packager Labor Hours

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.

Aeration Blower Control Efficiency

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.

Modern Woodcrafts Automates with Robotic Arms and Intelligent VSD Vacuum Pumps

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.”

Blower Requirements with DO Control

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.

The Importance of Particle Velocity in Dilute Phase Pneumatic Conveying

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.

Busch Provides Reliable Oxygen Supply to Aeration Tanks

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.

The Heart of Pneumatic Conveying Systems - Positive Displacement Blower Calculations

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".

Vacuum System Fundamentals for “Compressed Air People”

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.

7 Questions to Ask Before Buying a Vacuum Pump

Vacuum pumps are used for a wide range of applications in a variety of industries, but not all vacuum pumps are created equal. Before selecting a vacuum pump, take a look at the following questions. Knowing the answers will not only help you streamline your purchasing timeline, it will also ensure you get the right vacuum pump for your application.
