Micropollutants, such as antibiotics and flame retardants, can pose a health threat to animals and humans, even in tiny concentrations. Current methods to remove micropollutants from the environment include adsorption onto powdered activated carbon, which is then separated from the…
Researchers from the University of Colorado Boulder (Boulder, Colo.; www.colorado.edu) have developed a technology that combines wastewater treatment and carbon capture, resulting in a carbon-negative process that actually produces energy. The technology — called microbial electrolytic carbon capture (MECC) —…
Polylactic acid (PLA) is the biodegradable polymer of lactic acid, which is produced via fermentation processes. For the last five decades, PLA has been mainly used in biomedical applications. The development of economical production routes and a rising environmental awareness…

The pipe-flow equation presented here can be used to properly and easily size pipelines for liquid, vapor and two-phase flow. Example calculations are also shown Sizing pipelines is a fundamental task for design engineers, who typically use several equations to…
In cases where full containment of dangerous and hazardous chemicals is necessary, seal-less pumps can provide many safety and operational benefits To the average person, many of the raw materials that are commonly used in the chemical process industries (CPI)…
Mobile app and vibration sensors monitor machinery The SKF Enlight platform combines a new mobile app with a Bluetooth-enabled vibration sensor to enable staff to collect machinery data with no special training (photo). This allows standard mobile devices, such as…
Turndown and rangeability have a big impact on the flexibility and efficiency of chemical process operations During the design of a chemical process plant, the main focus is on which process units or unit operations must be integrated to convert…
Secondary treated wastewater from municipal plants can be a water resource for industry. Important water characteristics and treatment options are discussed Water is a precious resource, and water quality and water pollution are important issues. Many companies and industries are…
