An assessment of biodegradability was carried out for fragrance substances containing quaternary carbons by using data obtained from OECD 301F screening tests for ready biodegradation and from Biowin and Catalogic prediction models. Despite an expected challenging profile, a relatively high percentage of common‐use fragrance substances showed significant biodegradation under the stringent ...

An anaerobic membrane bioreactor and aerobic granulation technologies were tested at laboratory scale to treat winery wastewater, which is characterised by a high and variable biodegradable organic load. Both technologies have already been tested for alcohol fermentation wastewaters, but there is a lack of data relating to their application to winery wastewater treatment. The anaerobic membrane ...

Two different binder materials of varying water affinity, viz. poly vinyl alcohol (PVA) and poly-tetrafluoroethylene (PTFE), and biocide vanillin were tested for cathode fouling in a single chamber air-cathode microbial fuel cell (MFC) constructed with a low-cost baked clayware cylinder and operated under fed-batch mode. PVA and PTFE loadings of 0.5 mg/cm2 were used for MFC-1 and MFC-2, ...

 AlertMeter is sensitive to a number of issues that diminish alertness. When an employee's AlertMeter performance suggests that he or she may be experiencing diminished alertness and may be impaired, their test score is considered Outside Normal Range, or "ONR." So what should happen when an employee scores ONR on the AlertMeter test? Principally, AlertMeter's purpose is to ...

Just like a poorly poured pint of beer can wreak havoc on your coffee table, excessive foam formation in aeration tanks can create operational challenges for both municipal and industrial treatment plant operators.  In municipal plants, foam formation is common during secondary treatment startup, as the young microbiology is unable to breakdown surfactants associated with soap, shampoo, ...

The development of specific regulatory persistence criteria and a growing need to conduct risk assessments in sediment has increased the need to better understand fate in this compartment. A simplified test approach was developed to assess the fate of chemicals in aerobic sediments and was used to evaluate the biodegradation of 14C‐labeled representative analogs of alcohol sulfate (AS), ...

This paper examines the possible factors that contribute to the dispersive behavior of compacted nonswelling clays and proposes the use of a synthetic organic stabilizing agent to reduce the dispersive tendency of such soils. Results of chemical tests on saturation extracts of the clays tested failed to identify them as piping susceptible. However, pinhole tests on statically compacted specimens ...

Produced waters are the largest waste associated with the production of oil and gas; they contain dissolved salts, oil (dissolved and scattered organic compounds), chemicals and additives involved in the oil well operations, suspended particles, sand and other compounds, making their treatment very complex. In this paper, we propose the use of a TPPB (two phase partitioning bioreactor) for the ...

Forensic experts in Mumbai have solved the problem of analysing old viscera samples for intoxicants by using GC-MS. The Directorate of Forensic Science Laboratories (FSL) recently commented on a case they are working on involving the death of a man in Mumbai. In this case there is ambiguity as to whether or not the deceased man had intoxicants, such as drugs or alcohol, in his system ...

Food adulteration has been around since the Victorian times when cheese was often coloured with lead salts, beer and milk were watered down and flour was bulked out with chalk dust or ground bones [1]. Governments apply stringent legislation and quality standards to food products but the practice of adulteration, driven by greed and profit, is still seen. ...
