INDUSTRIAL BLOWER & VACUUM SYSTEMS

Optimizing Booster/Liquid Ring Vacuum Pump Performance with a Plastics Manufacturer

By Michael Cicalese and Chris Halbach, Wintek Corporation

Wintek Corporation was contacted by a plastics manufacturing company in the summer of 2015 to evaluate their process vacuum capabilities. The customer was looking to replace a recently purchased used vacuum system to be used in a PET solid state polymerization/drying application. The process required high heat and vacuum and needed to run at 1 mBarA (0.75 Torr). The customer had purchased the dryer and accompanying vacuum system from an overseas supplier. While they were happy with the dryer, the vacuum system was not delivering the desired performance.

Select the Right Vacuum Pump By Tie Duan, E.W. Klein & Co.

By Tie Duan, E.W. Klein & Co.

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.

AERATION BLOWER SYSTEMS

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

By David Lauer and Sarah Elger, EnviroMix

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.

Measuring Blower Airflow in the Field

By Tom Jenkins, JenTech Inc., and John Conover, Tamturbo Inc.

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).
