Monitoring the oxygen transfer efficiency of full-scale aeration systems: investigation method and experimental results
This paper reports the results of a series of off-gas tests aimed at monitoring the evolution of the oxygen transfer efficiency in an urban wastewater treatment plant (3,500 population equivalent) located in Tuscany (Italy). The tests were conducted over a 2-year period starting with the testing of the aeration system. It was found that in the absence of membrane-panel cleaning operations, the ...

Detailed off-gas measurements for improved modelling of the aeration performance at the WWTP of Eindhoven
At wastewater treatment plants (WWTPs), the aerobic conversion processes in the bioreactor are driven by the presence of dissolved oxygen (DO). Within these conversion processes, the oxygen transfer is a rate limiting step as well as being the largest energy consumer. Despite this high importance, WWTP models often lack detail on the aeration part. An extensive measurement campaign with ...

Nuclear reactor coolant removal monitored by hydrogen measurements provided by Systech`s 542 programmable gas analyzers
NNC Limited is using Systech's 542 programmable gas analyzers to monitor hydrogen off-gas in test rig for Dounreay Fast Breeder Reactor decommissioning. Decommissioning nuclear reactors is not only a matter of dealing safely with the radioactivity issues, non-nuclear contamination can be equally difficult to remove safely and economically. NNC Limited is currently developing a system to remove ...

Analyzing waste gases during simulated Mars mission - Case study
As part of a project to measure the effects of long-term isolation on astronauts, small groups of individuals have been selected to live in a tiny ‘Habitat’ perched on the upper slope of a volcano in Hawaii. In doing so, the project team has contributed to the understanding of issues that would confront a manned mission to Mars. As part of the project’s research NASA’s ...

What Equipment to Use for Fermentation Monitoring
Fermentation is, arguably, one of the oldest forms of biotechnology: humans have exploited the metabolic power of yeast and other naturally occurring microorganisms to produce alcoholic drinks, bread, and other fermented foodstuffs for thousands of years.1,2 Fermentation still plays a vital role in human development. Definitions of what exactly constitutes “fermentation” vary – ...

QIC-Biostream - exhaust gas analysis of small scale fermenters
Summary The application of the Hiden QIC-Biostream gas analysis system is to monitor the off-gas and vapours from up to 80 small scale fermenters for yield optimisation and process screening. Introduction Biotechnology is an extremely important area for the 21st century and information relating to yield of a product is crucial to most Biotech Companies. From a research perspective, it is very ...

Making wet waste destruction a sustainable reality
Irish environmental company SCFI was supported by the European Union’s Eco-Innovation initiative in a project to build a portable unit to demonstrate its innovative AquaCritox wet waste treatment technology. This White Paper describes the science behind hydrothermal oxidation (HTO) as a waste treatment methodology and its potential across a range of industrial applications, which is now, ...
