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. 

Considerations for Sizing Vacuum Pumps in High Humidity Applications

Many of us are familiar with sizing vacuum pumps based on throughput, process pressure requirements, chamber size, pump down times, conductance and leakage. In a lot of cases, humidity becomes an afterthought and unexpected things happen. Some of these unexpected things we learn to live with, like emulsified oil. In other cases, the unexpected things prevent the pump from performing the job it was intended for. 

Measuring Blower Airflow in the Field

Most electric utilities offer customer incentives for implementing energy conservation measures (ECMs) Incentive programs pay customers to use less energy. In some cases they are mandated by legislation and in others the incentives are driven by the utility’s desire to avoid building new generating capacity. Some incentives are based on reduced energy use (kWh) and some are based on lower peak demand (kW).

Rethinking Aerobic Digestion Resolves Frustrations, Improves Performance, and Saves Money

Aerobic digestion is a common treatment technology used at small-to medium-sized wastewater treatment plants for the treatment of waste activated sludge (WAS). The objective of aerobic digestion is to treat the sludge for disposal, and for those trying to meet Class B biosolids, further reduce volatile solids (VS) and pathogens to ensure the sludge is suitable for land application.

Blower Upgrade Saves Fraser Colorado Wastewater Treatment Plant Energy Costs

When the plant’s original aeration blowers became costly to operate and newer technology offered the promise of energy-savings, Fuqua took decisive action and replaced the older blowers with high-speed turbo blowers. As a result, the plant saves ratepayers approximately $30,000 per year in energy costs and bolsters the plant’s ability to maintain uptime and achieve extremely clean effluent.  

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.

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.

Engineered Vacuum Solution Saves Oregon Brewer 5,000 Gallons of Water Per Day

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.
