Factors affecting the performance of a single-chamber microbial fuel cell-type biological oxygen demand sensor
Microbial fuel cells (MFCs) are devices that exploit microorganisms as biocatalysts to degrade organic matter or sludge present in wastewater (WW), and thereby generate electricity. We developed a simple, low-cost single-chamber microbial fuel cell (SCMFC)-type biochemical oxygen demand (BOD) sensor using carbon felt (anode) and activated sludge, and demonstrated its feasibility in the ...

In-Situ® Optical RDO® Methods for Dissolved Oxygen Measurements Outperform Traditional Methods
ABSTRACT Three methods are generally used to measure dissolved oxygen (DO) in surface waters: Winkler titration, membrane-covered electrochemical sensors (polarographic or galvanic cell), and luminescent-based sensors. Optical (luminescent) technology for measuring DO levels in water has quickly become a well-accepted method due to many advantages over membrane-based sensors, and its close ...

Biodegradability of industrial textile wastewater – batch tests
Following new trends we applied oxygen uptake rate (OUR) tests as well as long-term tests (in two batch bioreactors systems) in order to assess the biodegradability of textile wastewater. Effluents coming from a dyeing factory were divided into two streams which differed in inorganic and organic contaminants loads. Usefulness of the stream division was proved. Biodegradation of the low-loaded ...

What is a portable dissolved oxygen detector
Introduction of Portable Dissolved Oxygens Detector: Dissolved oxygens analyzer is based on electrochemical principles. That is, on two different metal electrodes in the measured electrolyte solution containing oxygen. Oxidation-reduction reaction will occur, and the resulting diffusion current has a certain relationship with the oxygen concentration in the solution. It is an instrument for ...

Success of Onlin Leads to Closing for Wastewater 2 Process Control of Consent Order Treatment Plant
In 2003, Plant City, a small Florida city of 30,000 residents, faced a very big problem. The Florida Department of Environmental Protection (FDF.P) determined that the city's wastewater treatment plant was not consistently operating within its permit limits, and placed it under a consent order. Plant City is a highly industrialized area. "Our industrial loading is very diverse and includes metal ...
