Redox mediators (electronophores) and metabolic uncouplers (protonophores) play a major role in the sub‐atomic particle transportation in chemical and biological processes. Application areas include activated sludge treatment, excess biomass removal, bio‐filtration of gaseous pollutants, electricity generation by means of solar or microbial fuel cell (MFCs), biosensors, and dye degradation. Through a detailed review of peer‐reviewed and environmental literature, redox mediators and metabolic uncouplers, their mode of action as well as major factors influencing the redox mediators and metabolic uncouplers are discussed. This review article will help researchers to enhance their understanding of the application of redox mediators and metabolic uncouplers in environmental research.

“…Proper content of organic matter in the filtering medium is also necessary for maintaining the proper amount and activity of microorganisms. According to [17], the content of organic material in the biofilter medium should amount to a minimum of 55 %, and the ration of elements C:N:P -100:5:1. Pursuant to [10], the proportions between carbon, nitrogen, and phosphorus should be maintained at a level of 200:10:1.…”

The objective of the study is research on a biofilter existing at a mechanical-biological waste treatment plant in Radom. The paper presents results of research on the filling of the analysed biofilter (moisture, organic matter content, nutrient content, pH, grain size composition, and equivalent diameter), process gases (temperature, humidity and pH, concentrations of the main pollutants - ammonia, hydrogen sulphide, volatile organic compounds, acetic acid, ethanol) and operational parameters (flow rate, height of the biofilter layer, surface load, gas residence time in the filter bed). Irregularities were observed related to biofiltration efficiency, particularly resulting from improperly selected filling material and improper biofilter operation. The technological research permitted the identification of problems and determination of the requirement of performing necessary operational changes. Further works will involve the design, manufacture, and installation of an integrated biofilter with two-stage gas purification process (a classic biofilter and a semi-permeable membrane).

“…1 Prolonged exposure to VOCs can damage the liver and central nervous system. 2 VOCs can be captured and, in some cases, removed from the air through several techniques such as adsorption, 3 absorption, 4 oxidation, 5 incineration, 6 biofiltration, 7 condensation, 8 and membrane separation. 9 Compared to other control techniques, adsorption is more cost-effective and efficient.…”

A microbead-assisted planar microwave resonator for organic vapor sensing applications is presented. The core of this sensor is a planar microstrip split-ring resonator, integrated with an active feedback loop to enhance the initial quality factor from 200 to $1 M at an operational resonance frequency of 1.42 GHz. Two different types of microbeads, beaded activated carbon (BAC) and polymer based (V503) beads, are investigated in non-contact mode for use as gas adsorbents in the gas sensing device. 2-Butoxyethanol (BE) is used in various concentrations as the target gas, and the transmitted power (S21) of the two port resonator is measured. The two main microwave parameters of resonance frequency and quality factor are extracted from S21 since these parameters are less susceptible to environmental and instrumental noise than the amplitude. Measured results demonstrate a minimum resonance frequency shift of 10 kHz for a 35 ppm concentration of BE exposure to carbon beads and 160 kHz for the polymer based adsorbent at the same concentration. The quality factor of the resonator also changed for different concentrations, but a distinguishable variation is observed for the BAC adsorbents. The high quality factor of the sensor provides the opportunity of real time monitoring of the adsorbent behaviors in remote sensing mode with very high resolution. V C 2015 AIP Publishing LLC.
