Industrial standards provide a common means of understanding and communicating performance. This article examines the rationale and applications of the Compressed Air & Gas Institute’s standards for determining the energy efficiency of low-pressure blower packages.

This guide explains three blower technologies and,using examples from actual wastewater plants, describes the most effective technology for particular applications and why. Of course there is no substitute for a consultation specific to your application; however, the guide can help raise the right questions and ensure a productive vendor and technology evaluation process.

DEKKER Vacuum Technologies is helping DuPont Titanium Technologies, the world’s largest manufacturer of titanium dioxide, meet the world’s needs for this essential chemical. DEKKER has custom designed and manufactured two vacuum pump systems that will be incorporated into DuPont Titanium's $500-million titanium dioxide capacity expansion project at its plant in Altamira, Mexico.

Formaldehyde is an organic compound that can adopt several different forms. It can be used in solution form as formalin, as a free gas, or in a solid form as paraformaldehyde prills. Formaldehyde is highly toxic to humans, regardless of the method of intake. At room temperature it is a colorless gas characterized by a pungent odor. Even with very short-term exposure, formaldehyde will cause irritation to the eyes including pain, redness, blurred vision followed by sneezing, soreness, coughing, shortness of breath, headaches and nausea. Exposure to elevated levels can lead to accumulation of fluid in the lungs (pulmonary edema).

A grand opening ceremony was conducted yesterday at the Holiday station located at 3931 West First Street in Duluth, Minnesota. This marks Holiday’s first compressed natural gas (CNG) product offering to its customers. Trillium CNG™ designed, built and will maintain the public access fast-fill CNG station.

High speed bearing technology is applicable for aeration blowers operating at much higher speeds than the typical 60Hz, 3600RPM for cast multistage units. High Speed Turbo (HST) units are usually single stage (though some utilize multiple cores) and rotate from 15,000 to 50,000RPM. At such high speeds, standard roller bearings cannot offer the industry standard L10 bearing life. Two types of bearing technologies have come to dominate the wastewater treatment market for these types of machines: airfoil and magnetically levitated. Often the two technologies are compared as equals, however, in many significant ways they are not.

Blower & Vacuum Best Practices interviewed Frank Mueller (President) and Stephen Horne (Blower Product Manager) from Kaeser Compressors.

Kaeser Compressors continues to grow both in the U.S. and internationally. We currently employ approximately 4800 people globally. In order to support the demand and maintain our superior quality and quality service levels, we continue to invest in people, facilities and technology.

Productivity is more reliable when equipment can be monitored to detect incipient failures and take corrective action before the plant goes down. But many devices, such as analog control valves, pneumatic valve terminals and field sensors, often do not offer diagnostic feedback, or it is not being used. This white paper describes how this problem is being addressed, and includes an example of pneumatic valve terminals that can monitor, among other things, open load or coil currents at the specific valve and pressure inside the valve terminal.

With the continuing increases in energy costs and the requirements of Biological Nutrient Removal (BNR), the design of the aeration system has become one of the most important aspects of the design of the activated sludge process.

Intertape Polymer Group (IPG) is a manufacturer of tapes, films, woven fabrics, and complementary packaging systems for industrial and consumer use. The company operates 10 production plants and employs approximately 1,800 people. IPG has developed a robust energy management program by using ENERGY STAR energy management tools and actively participating in the ENERGY STAR partnership. IPG is receiving ENERGY STAR recognition for the growth of its energy program and leadership as a medium-sized manufacturer.
