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!

Aeration Blowers

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.

Industrial Blowers

Blower systems designed to deliver continuous airflow at pressures of 50 psig or below are critical to the operation of many processes including wastewater treatment, pneumatic conveying, fluid catalytic cracking, and fermentation to name a few. Many circumstances could arise that require an operator to require a rental blower for a period.

Rough Vac

Many heat-treating applications put difficult demands on vacuum pumps in general and oil-sealed pumps, in particular. Byproducts from the heat-treating process can contaminate the vacuum pump oil and create higher vapor pressures that cause deteriorated vacuum levels in the heat-treating chamber, or buildup and blockages in the pump mechanism.

Medium/High Vac

Distillation, degassing, drying, filtration, membrane separation, adsorption, and crystallization are all among the separation processes that rely on the differences in the physical properties of substances in a mixture. Distillation relies on the differences in boiling point or in vapor pressure versus temperature characteristics. Heating, evaporation, and condensing are the tools used in distillation that separate the liquid constituents in a liquid mixture.

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.  
Aeration tanks use bubble diffusers to distribute oxygen within the wastewater. Fine bubble diffusers, or those that produce a large amount of very small air bubbles, first began to become popular in the 1980s, as they had a much higher efficiency than coarse bubble diffusers. Fine bubble diffusers generally feature a membrane that allows airflow to pass from the piping system on the floor of the tank through the body of the diffuser and the membrane, providing oxygen into the wastewater for treatment.
The design of wastewater treatment plants is changing, and it has something to do with LEGO® bricks. More specifically, it has to do with how large and complex LEGO structures are built. If you follow the instructions carefully, you build module after module, eventually piecing them together to create a fully functional and cohesive unit.
A replacement strategy for air compressors and blowers integrated into a system-level approach towards energy efficiency can deliver significant energy savings and optimize equipment performance. At the Victor Valley Wastewater Reclamation Authority, a blower replacement project yielded annual energy savings of more than 928,000 kWh and $98,000 in energy costs, while improving the reliability of its secondary treatment process. In addition, the agency qualified for important incentives from its electric utility — significantly improving the project economics and resulting in a 2.94-year payback.
The overall wastewater treatment process is complex, and each step is integral to ensuring water is properly purified. Effluent ends up in the plants, containing substances that must be removed before the water can be properly cleaned and returned for use. The range of potential contaminants is almost endless and can include food, pulp, waste, or other substances. Afterwards, the water requires further scrubbing, with the aid of bacteria. It is in this part of the process that compressed air (ideally provided by energy-efficient rotary lobe blowers) plays a vital role.

We were fortunate enough to speak with Keith Webb, the Application Engineering Manager at Tuthill, to learn about the company and its manufacturing equipment. During our discussion, we talked about the company’s blower and vacuum technologies, common markets and applications, and Tuthill’s custom-engineering capabilities. Webb even touched on some trends in energy management regarding blower and vacuum systems.
“What is the best type of oil to use in my vacuum pump?” is a common question for sure, and one that may often yield confusing and conflicting answers. The rule of thumb is that it is always best to follow OEM recommendations, but why do they recommend the lubricants that they do? For the purpose of this article, we will focus on some of the general industrial vacuum pump applications and their lubricant choices.
The NPE 2015 International Plastics Showcase was held at the Orange County Convention Center in Orlando, Florida, March 23-27. The Show attracted 2,029 exhibitors - including Blower & Vacuum Best Practices Magazine!  Over 1,128,000 square feet of exhibition space was used – both figures breaking the all-time NPE records set in 2000. Held once every three years, NPE registered attendance was 65,810 – 19% greater than the 2012 event.
Hannover Messe 2015 attracted 220,000 visitors with 70,000 coming from outside Germany. The blower and vacuum industry was very well represented and presented itself as a very healthy industry with high levels of innovation and activity. The goal of this article is to provide readers with a sampling of highlight technologies catching my eye – with apologies to the many companies left out due to editorial space limitations.
Many manufacturing processes are like offensive linemen. When everything is running smoothly, nobody tends to notice. But, when an application starts creating a hazardous work environment (think too many blindsided sacks), or the products start spoiling (think shutout or a losing season), you best believe someone will start paying attention.
