Industrial Utility Efficiency


By using state-of-the-art vacuum technology for degassing mineral water, it has been possible to save an average of 3,000 cubic meters of water per filling plant per year. The solution was to replace the existing liquid ring vacuum pumps with MINK claw vacuum pumps from Busch Vacuum Solutions.

Considerations for Temporary Blower Air at a Wastewater Treatment Facility

This article aims to discuss the various technologies of equipment that could be presented to a wastewater operator faced with a temporary need for blower air and to help the operator understand the impact (both monetarily through a “Total Cost of Rental” approach and environmentally) of their decisions.

Aeration Blower Control Strategies

Real world blower applications rarely operate at steady state design conditions. There are a variety of reasons for this. Designs usually include a margin of safety to accommodate unforeseen conditions. Typically, the process demand itself is variable, requiring a corresponding ability to modulate the blower flowrate.

Case Studies in Dry vs. Wet Vacuum Pumps

We present a few case studies derived on real-world application examples, where various vacuum technologies may be suitable solutions. Each case is generalized enough that the knowledge is applicable across multiple specific applications.

Liquid Ring Vacuum Pumps and Food Applications

The food industries can have many messy processes, whether it is poultry evisceration, deboned waste conveying, bottling, or sugar cake filtration. Liquid ring vacuum pumps (LRVP’s) are often utilized as the backbone of these processes because they can handle the soft solids, debris, and particles that can easily get sucked into the vacuum pump. So how does a LRVP work, why does it work in these processes, and how to make sure they keep working?

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. 

Design Engineering a WWTP Expansion with Unique Site Constraints

A small site located within a floodplain, prone to erosion, and currently occupied by an existing in-service wastewater treatment facility is not at the top of any engineer’s list for a desirable site to expand a wastewater treatment plant or reclamation facility. However, these challenges created opportunity for specialized solutions during the design of the facility expansion; in particular, in designing the aeration and digester blower system.

WWTP Saves Energy in Biogas Recovery Process

Ever since it was commissioned in 1974, the Echallens wastewater treatment plant in the Swiss canton of Vaud has been generating power from the recovery of biogas. In May 2020, two old oil-lubricated piston compressors used to mix the sludge in the digester were replaced by one MINK claw compressor from Busch Vacuum Solutions. This enabled the amount of power required for this process to be reduced by up to 40 percent. For the director of the treatment plant, this means he needs less energy to produce energy.

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).

Select the Right Vacuum Pump

Deciding on the most suitable vacuum technology for an industrial application can be challenging. This decision can be relatively easy if it is simply finding a drop-in replacement for an existing pump, but if a process keeps crashing an existing pump, it can get complicated when you are tasked with re-evaluating all the available options to find the best solution. I am hoping to highlight a few key factors to consider when you run into this type of scenario.
