Intelligent Sensor Management (ISM) is an innovative solution for analytical process parameters that simplifies sensor handling and improves maintenance management. This translates into increased process reliability and reduced operating costs. ISM’s wide parameter breadth (pH, ORP, O2, CO2, conductivity, turbidity,…
At Achema 2018 (June 11–15; Frankfurt am Main, Germany), EvCon GmbH (Pliening-Landsham, Germany; www.evcon-water.com) showcased its new UPWater treatment system, which employs a patented vacuum multi-effect membrane distillation (VMEMD) technology to obtain ultra-pure water using less energy than comparable water-treatment…
Last month, Nano Sun, a water technology start-up founded by a scientist from Nanyang Technological University (NTU; Singapore; www.ntu.edu.sg) launched a 3-D-printing facility to manufacture a new type of water-treatment membrane. Unlike conventional membrane-manufacturing processes, which use acids to make…
Drying biosludge from wastewater-treatment plants is complicated by the “sticky phase,” making the practice more of an art than a science. Discussed here are efforts to define the beginning and endpoints of this phase analytically The drying of biosludge from…
The development of denitrification catalysts that can reduce nitrate and nitrite to N2 is critical for sustaining the nitrogen cycle. However, regulating the catalytic selectivity has proven to be a challenge, due to the difficulty of controlling complex multi-electron/proton reactions.…
A thermal-membrane process system, based on the Joule-Thompson effect (JTE) for treating wastewater with high salinity or with a high-level of inorganic contents has been developed by Thermosift Engineering Pvt. Ltd. (Asaripallam, Tamil Nadu, India; www.thermosift.com). The system operates at…
The following recently published titles may be relevant for chemical process industries (CPI) professionals: Biomass as Renewable Raw Material to Obtain Bioproducts of High-Tech Value. Edited by Valentin Popa and Irina Volf, Elsevier Press, 2018, e-book, $31.50 per chapter. Dealing…
A process that produces renewable hydrogen from organic biowaste and reduces the economic and environmental burden of wastewater treatment is being developed by Chemergy, Inc. (Miami Fla.; www.chemergy.com). Introduced at last month’s AIChE Spring Meeting (April 22–26; Orlando, Fla.), Chemergy’s…
The activated sludge process (ASP) is designed to speed up the rate of decomposition of waste material in water. First developed in 1914, it remains an important means of treating both municipal and industrial wastewaters. This one-page reference provides information…
A new adsorption-based technology can separate ozone from oxygen in O3-generating systems, allowing recycling of unreacted O2. In corona-discharge O3 generation, O2 molecules are split by passage through an electric field to create free oxygen atoms, which quickly combine with…
