Preparation of a fouling-resistant sustainable cathode for a single-chambered microbial fuel cell

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, ...

$Towards sustainable repairs: substrate–repair interface mode–I fracture analysis$

Towards sustainable repairs: substrate–repair interface mode–I fracture analysis

An experimental programme for the optimisation of concrete structural and non–structural repair was performed. The programme focused on the development of sustainable durable repairs throughout the enhancement of substrate–repair bond and compatibility, as well as the development of efficient solutions for crack control. As part of the programme, mode–I fracture characterisation of a ...

5 best practices for handling outside-normal-range alertmeter scores

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 increase awareness ...

An assessment of biodegradability of quaternary carbon containing fragrance compounds: Comparison of experimental OECD screening test results and in silico prediction data

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 ...

Determination of biodegradation rates for surfactants and a fatty alcohol in aerobic sediment using a simplified test system

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), ...

Dispersive Behavior of Nonswelling Clays

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 ...

Learn how GC is used in Alcohol Profiling to ensure product quality and to keep consumers safe

Gas Chromatography (GC), a core technique for separating and analyzing compounds, is commonly used across multiple industries. One of those industries is the alcohol industry, where GC is used to keep consumers safe and to ensure flavors are at their best. In beer analysis and brewing, beverages are characterized by complex mixes of compounds which create the signature aromas and flavors enjoyed ...

Two phase partitioning bioreactor applied to produced water treatment

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 ...

Fighting Foam in Aeration Tanks

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, etc. ...
