Last month at the IFAT trade fair (May 30–June 3; Munich, Germany), Huber SE (Berching: www.huber.de) and Microdyn-Nadir GmbH (Wiesbaden, both Germany: www.microdyn-nadir.de) unveiled a rotating membrane bioreactor (MBR) that utilizes membrane laminate technology. “By combining our two technologies we…
By the end of this year, a demonstration plant will start up in the U.S. that uses an electrochemical process to recover phosphorus from wastewater, producing a fertilizer as struvite (NH4MgPO4·6H2O). Although the location and capacity of the plant has…
Polylactic acid (PLA) is a versatile biopolymer, but its applications are somewhat limited due to its brittleness. Now, an alternative bio-based composite material has been developed that overcomes this limitation. Developed by the industry-university consortium of Hitachi Zosen Corp. (HITZ;…
Cooling-tower motor A new electric motor for driving cooling-tower fans features a design that prevents current from flowing through the shaft bearings, allowing longer lifetime and less maintenance. The TEAO motor, made by Marathon Motors Corp. (Wausau, Wis.; www.marathonelectric.com) also…
A hybrid process that combines micro-flotation and flat-sheet ceramic-membrane filtration to remove oil and suspended solids from difficult-to-treat industrial wastewater has been commercialized by akvola Technologies (Berlin, Germany; www.akvola.com). The system can treat water with high oil loads (up to…
A direct copolymerization of carbon dioxide and diols has been achieved by Keiichi Tomishige and Masazumi Tamura at Tohoku University (Sendai; www.che.tohoku.ac.jp) and Hiroshi Sugimoto at Tokyo University of Science (both Japan; www.sut.ac.jp). The synthesis takes place with a metal-oxide…
A new smartphone-operated portable chemical analyzer provides a platform for chemical leak detection and other industrial applications, according to developer MyDx Inc. (San Diego, Calif.; www.cdxlife.com). The company designed the handheld analyzer for consumers, but the technology platform has origins…
The manufacture of pharmaceuticals and many fine chemicals requires costly, toxic catalysts with metal atoms bonded to complex organic ligands that catalyze the creation of chiral centers. Current processes often use homogeneous (dissolved) chiral catalysts and batch processing, an approach…
Conversion of carbon dioxide into useful carbon sources, such as carbon monoxide, formic acid and formaldehyde, is attracting considerable interest as a way to recycle and utilize CO2. A step in this direction is the direct photocatalytic reduction of CO2…
At the Hannover trade fair (April 24–29; Hannover, Germany), ABB (Zurich, Switzerland; www.abb.com) introduced a new sensing solution for monitoring low-voltage motors. Smart sensors attached directly to the motor supply information regarding operating and condition parameters via wireless transmission. The…
