Industrial Utility Efficiency

System Assessments

Vacuum can be used in many ways for the meat processing and packaging industry. From mixing ingredients to evisceration (removing organs, excess fat, bones, etc.), to the washing/preparation of the meats or even in the packaging of the meat itself, vacuum is critical to the industry.

Leveraging Rental Blowers for Pneumatic Conveying Applications

Pneumatic conveying applications are critical to many facilities – when you can’t move material you can’t make or sell your product. Because of a historical lack of availability of specialized rental blowers and air compressors for pneumatic conveying, plants often either accepted the production outage or rented a more readily available two-stage, oil-free rotary screw air compressor designed for 90 to 150 psig plant air service that is very inefficient at the reduced pressures needed for pneumatic conveying.

Meat Processor Saves Millions of Gallons of Water with Engineered Vacuum Solution

Helping Wisconsin Wastewater Treatment Facilities Save Energy

Leidos Engineering, LLC., is responsible for implementing the Wisconsin Focus on Energy® Large Energy Users (LEU) Program in Wisconsin. Blower & Vacuum Best Practices interviewed Leidos Engineering’s Joseph Cantwell, P.E., Senior Energy Management Professional, Focus on Energy – LEU Program, to learn how the firm works with Focus on Energy to help wastewater treatment facilities in the dairy state reduce energy consumption and save costs.

The Basics of Aeration Control Valves - Part 1

Sizing, selection, and adjusting control valves often causes confusion for process and control system designers. Improper valve application can cause operating problems for plant staff and waste blower power. Basing the airflow control system design on fundamental principles will improve valve and control system performance.

When Craft Brew Alliance (CBA) set a goal to dramatically reduce water consumption at its Widmer Brothers Brewery in Portland, Oregon, it focused its efforts on its bottling process – and implemented a solution engineered by Atlas Copco that saves 5,000 gallons of water per day. In addition, it saves the craft brewer $39,000 per year, thanks to the elimination of water treatment costs and reduced energy use. Brown and Caldwell: Tackling Wastewater Aeration Challenges Blower & Vacuum Best Practices interviewed Henryk Melcer, Senior Process Engineer, Vice President, at Brown and Caldwell. We’re headquartered in Denver, Colorado. In all, we have more than 1,700 professionals working in nearly 50 locations, primarily in mainland USA. About 45% of our work is focused on wastewater engineering now, having made a conscious effort to diversify into water treatment and industrial wastewater treatment. That was after we absorbed Dr. Eckenfelder’s old company, which is ironic because it came full circle for me. We also carry out environmental impact assessments, water resources modeling, collection system and stormwater modeling, and a range of other services. Sni-A-Bar Wastewater Plant Saves$42,000 Annually in Energy with New Aeration Blowers

After auditing and field-testing, the Sni-A-Bar Municipal Wastewater Plant in Blue Springs, Missouri, partnered with Inovair to replace 4 fixed-speed rotary lobe blowers on its aeration system with 4 Variable Frequency Drive (VFD), integrally geared centrifugal blowers. The new blowers, along with improvements in blower controls, reduces annual energy use by 442,664 kWh and peak electrical demand by 48.76 kW, which translates to an annual energy reduction of 37 percent and anticipated savings of $42,000 per year. Additionally, a rebate of$45,799 from the local utility resulted in a payback of less than six years.

Central Vacuum Supply for Efficient Cheese Packaging

DMK Deutsches Milchkontor GmbH produces sliced cheese and Mozzarella at its production facility in Georgsmarienhütte, Germany. The various types of sliced cheese and Mozzarella blocks are vacuum packed after processing in several packaging lines. The vacuum supply for the packaging machines is provided by a Busch centralized vacuum system, which supplies both the packaging lines and the thermoforming machines.

Solving the Top Challenges of Industrial Vacuum

Industrial vacuum can be defined as vacuum used to perform a task in industrial processes, operating anywhere from atmospheric pressure to 1 torr. Traditionally, the most common technologies included liquid ring and rotary vane vacuum pumps. But as with any industry, there was room for improvement... otherwise, we’d still be driving Model A Fords and talking on corded telephones. Luckily in recent years, the industrial vacuum market has started making significant advancements in technology and efficiency.

Reducing Demand in Industrial Vacuum Systems

This article will focus on optimizing the demand-side so the centralized “supply-side” (the vacuum pumps and controls) can then run at a lower energy and maintenance cost. First, I will start with a simplified model of a vacuum pump system demands. See Figure 1 for a one-pump/one-demand simplified system. See Figures 2-6 for some typical controlled and uncontrolled demands. The symbol with the three lines is an orifice, a hole essentially. I am defining three types of system demands adding up to the total demand on the vacuum pump.
