“…Lower power density values (65.82 mW/m 2 ) than that achieved in the present research ( Figure 3A) were reported by Zhang et al (2013) using diluted molasses in a two-chamber BES with an external resistance of 1000 Ω. Maximum power densities as low as 17.6 mW/m 2 were reported in two-chamber BES treating mining process wastewaters containing tetrathionate at pH below 2.5 with ferric iron as the terminal cathodic electron acceptor (Sulonen et al, 2014). On the contrary, maximum power density values as high as 1180 mW/m 2 were achieved in MFC treating wastewater produced in a bio-refinery process (COD: 5.3 g/L) containing residual sugars, 5-furfural, phenolics, and other pretreatment and fermentation by-products (Borole et al, 2013).…”

SUMMARY:Olive oil washing water derived from the two-phase manufacturing process was assessed as an electron donor in a bio-electrochemical system (BES) operating at 35 ºC. Start-up was carried out by using acetate as a substrate for the BES, reaching a potential of around +680 mV. After day 54, BES was fed with olive oil washing water. The degradation of olive oil washing water in the BES generated a maximum voltage potential of around +520 mV and a Chemical Oxygen Demand (COD) removal efficiency of 41%. However, subsequent loads produced a decrease in the COD removal, while current and power density diminished greatly. The deterioration of these parameters could be a consequence of the accumulation of recalcitrant or inhibitory compounds, such as phenols. These results demonstrated that the use of olive oil washing water as an electron donor in a BES is feasible, although it has to be further investigated in order to make it more suitable for a real application. KEYWORDS: Bio-electrochemical system; COD removal; Electricity generation; Electron donor; Olive oil washing watersRESUMEN: Idoneidad del agua de lavado de aceites de oliva como donador de electrones en un sistema alimentado por lotes bioelectroquímico. El agua de lavado del aceite de oliva procedente del proceso de elaboración en dos fases fue utilizada como donador de electrones en un Sistema Bioelectroquímico (BES) operado a 35ºC. Se realizó una etapa de arranque del sistema mediante alimentación con acetato, alcanzando un potencial de referencia de +680 mV. Tras 54 días, el sistema se alimentó con agua de lavado de aceite, generando un potencial máximo de +520 mV y una eliminación de materia del 41%, en demanda química de oxígeno. Sin embargo, cargas subsecuentes conllevaron una bajada en la eliminación de materia, mientras que la densidad de corriente y de potencia disminuyeron ostensiblemente. El empeoramiento de estos parámetros puede deberse a la acumulación de compuestos recalcitrantes o inhibidores, como fenoles. Por tanto, el uso del agua de lavado de aceite de oliva en un BES es factible, aunque es necesario llevar a cabo nuevas investigaciones que hagan más atractiva su aplicación a escala real.

“…Activity coefficients used here are based on the values reported by Zeleznik (1991). However, due to the exponential and nonmonotonic nature of activity coefficients, they cause numerical difficulties in CFD modeling; thus, a monotonic van Laartype equation fitted by Taleb et al (1996) from the data of Zeleznik (1991) was used.…”

Abstract. The homogeneous sulfuric acid–water nucleation rate in conditions related to vehicle exhaust was measured and modeled. The measurements were performed by evaporating sulfuric acid and water liquids and by diluting and cooling the sample vapor with a sampling system mimicking the dilution process occurring in a real-world driving situation. The nucleation rate inside the measurement system was modeled inversely using CFD (computational fluid dynamics) and the aerosol dynamics code, CFD-TUTMAM (Tampere University of Technology Modal Aerosol Model for CFD). The nucleation exponents for the concentrations of sulfuric acid and water and for the saturation vapor pressure of sulfuric acid were found to be 1.9±0.1, 0.50±0.05, and 0.75±0.05, respectively. These exponents can be used to examine the nucleation mechanisms occurring in exhaust from different combustion sources (internal combustion engines, power plant boilers, etc.) or in the atmosphere. Additionally, the nucleation rate can be expressed with the exponents as a function of the concentrations of sulfuric acid and water and of temperature. The obtained function can be used as a starting point for inverse modeling studies of more complex nucleation mechanisms involving extra compounds in addition to sulfuric acid and water. More complex nucleation mechanisms, such as those involving hydrocarbons, are observed with real vehicle exhaust and are also supported by the results obtained in this study. Furthermore, the function can be used to improve air quality models by using it to model the effect of sulfuric acid-emitting traffic and power generation on the particle concentration in urban air.

One of the first widely used, synthetically-produced pesticides was the organochloride class agent DDT. From the Second World War until its ban in the early 1970's, DDT was deployed on a vast scale for control of insects and insect-borne diseases and as a highly effective agricultural pesticide [11]. For example, over a half million pounds of DDT was applied to salt marshes in Cape May County, New Jersey
