    A 4-factor, multilevel, full factorial design of 240 experiments was performed in order to investigate the effect of temperature on the inactivation efficiency of spiked Escherichia coli in simulated solar disinfection of a synthetic secondary effluent. The initial population of the microorganisms was 103, 104, 105 and 106 CFU/mL, the exposure time 1, 2,3 and 4h, the treatment temperature 20, 30, 40, 50 and 60 degrees C and the sunlight intensity 0, 800 and 1200 W/m(2). Radical changes in bacterial behavior, process efficiency and remaining populations were observed, while treating effluents in discreet temperatures. Elevating treatment temperature from 20 to 40 degrees C drastically impaired disinfection. Thermal inactivation with no regrowth predominated at 50 degrees C and total inactivation of microorganisms was observed at 60 degrees C in nonirradiated samples. Irradiation at 800 and 1200 W/m2 much increased inactivation efficiency, especially at 50 and 60 degrees C, proving sensitive light-temperature synergy at those temperatures. Total inactivation was achieved within 4h under a range of treatment conditions, including all samples at 1200 W/m(2), or 60 degrees C samples at 800 W/m(2). Also, 99.9-100% efficiencies and final population below 1000 CFU/100 mL were obtained at 800 W/m(2) and temperatures of 50 degrees C and above. Treatment time, temperature and intensity are the critical parameters for the disinfection process, while initial population is insignificant for removal efficiency. An explanation of the mechanism of the process as well as a general linear model predicting the outcome of the experiments is also suggested. (C) 2014 Elsevier B.V. All rights reserved.

    In this study, we systematically investigate solar disinfection of synthetic secondary wastewater, with the effort to decrypt the effects disinfection conditions have on post-irradiation bacterial regrowth in the dark. A full factorial design of 240 experiments was employed to investigate the effects of (i) exposure time (1, 2,3 and 4h), (ii) treatment temperature (20, 30, 40, 50 and 60 degrees C), (iii) initial bacterial concentration (10(3), 10(4), 10(5) and 10(6) CFU/mL) and (iv) sunlight intensity (0, 800 and 1200 W/m(2)) on Escherichia coli survival for a subsequent 48-h dark control period. The decisive implications treatment temperature inflicted in regrowth were monitored and interpreted within two temperature ranges, from 20 to 40 degrees C and 40 to 60 degrees C. In dark tests, bacterial populations presented initial moderate growths at 20-40 degrees C range, followed by intense regrowth. At 40-60 degrees C range, acute thermal inactivation without long-term regrowth predominated at 50 degrees C and was total at 60 degrees C, within the 4-h treatment period. Introduction of light resulted in higher removal rates or permanent inactivation for 800 and/or 1200 W/m(2), respectively. No post-treatment regrowth in the dark was observed after 24 and 48 h, in completely inactivated samples, and its demonstration, when observed, was well correlated to the bacterial numbers at the end of the disinfection period. Statistical observations on the transferred bacterial populations from day to day are also discussed in this paper. (C) 2014 Elsevier B.V. All rights reserved.

    In this study, simulated solar disinfection of secondary effluent was followed by dark storage at different temperatures or different receiving water matrices. Escherichia coil illumination was followed by 3-day monitoring of the bacterial population and its adaptation in different temperature conditions in the dark. The subsequent survival was linked to the dose received during exposure to light, and results were obtained on the environmentally induced prolongation of survival, maintenance of population or excessive growth, at 4 degrees C, 20 degrees C and 37 degrees C, respectively. An additional set of experiments at 20 degrees C was subjected to dilution in E. coli-free synthetic wastewater, water from Lake Leman, (synthetic) seawater and Mili-Q water. Post-irradiation monitoring was also conducted, studying 50%, 10% and 1% dilution rates, and the results were attributed to the two parameters of dilution medium and dilution ratio. However, different responses were found based on the acquired dose during pre-treatment. This indicates the importance of the illumination prior to storage, and the preference of bacteria in some matrices over the others. Survival was linked to initial population, dose, dilution and medium; shorter illumination times are to be considered according to the receiving water matrix. (C) 2014 Elsevier B.V.

    In this study, the effect of light intermittence on solar disinfection of secondary treated wastewater was investigated. Synthetic secondary effluent was spiked with Escherichia coli and submitted to 3 different light intermittence regimes by circulating the effluent between a dark storage tank and three in-series illuminated reactors. The relative influence of the recirculation rate on bacterial inactivation was studied, in short (3¿7 min) light regimes and a dark-to-light ratio of 2.04. Lower recirculation rates resulted in poorer disinfection results, showing the detrimental effect of longer dark storage periods on the removal efficiency. Also, longer time intervals were employed in batch tests, to investigate the effect of 1, 2 and 3-h dark intervals, during recreated solar disinfection conditions; fourteen different scenarios were tested. Three hours of continuous or cumulative illumination were proven enough to provide the necessary dose to damage bacteria irreparably, while interruption during these hours favored bacterial resistance. Finally, absence of regrowth was observed in all cases that derived from samples with null bacterial counts. However, when a fraction of viable bacteria was present at the end of the solar treatment, survival was favored.

    In the Mamais-Jenkins-Pitt method for determination of readily biodegradable COD (SS), 2 alternatives were proposed for the intermediate determination of soluble inert COD (SI). When a full-scale treatment plant exists, influent SI = effluent truly soluble COD. When there is no full-scale plant, then the truly soluble COD of the effluent of a 24 h fill-and-draw batch reactor treating the wastewater is taken as influent SI. In this study, both SI methods were statistically compared on 24 wastewater samples from 2 municipal wastewater treatment plants (WWTPs). While average SI obtained for the 2 methods was the same, individual samples usually had very different SI values. In fact, virtually no correlation was found between the 2 methods. Also, the SS values obtained using both SI alternatives were statistically compared. A good correlation was observed, in spite of the poor SI correlation – low, dispersed SI values did not seriously affect the correlation between both SS determinations. A method was proposed for determination of the limit of detection and the limit of quantification (LOQ) for both SS methods. The LOQ resulted in 28.6 mg/l and 32.6 mg/l, respectively, for the full-scale and the laboratory-scale alternatives. Some assumptions of the original laboratory-scale (LS) method could potentially be sources of error in SI determination. Two modifications to the laboratory-scale method were implemented in order to avoid these potential problems: Washing biomass with tap water, and correcting SI in the fill-and-draw reactor by the SI of the original biomass suspension. These method modifications were tested on wastewater samples from the mentioned WWTPs. The fundamentals and results of both modifications are discussed in this paper, as well as the imprecision associated with estimating influent SI from effluent CODsol in all studied methods, and its impact on SS determination.

    Thirty-nine linear regression and time series models were built and calibrated for influent temperature (Ti) estimation at the primary aerated facultative lagoon in a municipal wastewater treatment plant. The models were based on mean daily ambient air temperature (Ta) and/or daily rainfall (P), and—optionally—wastewater temperature autoregression. The best fits were achieved with some time series models involving Ta and P, and Ti autoregression. The best-fit model was able to estimate influent temperature with a root-mean-square-error of 0.5 °C, and an R2 of 0.925, for the calibration period of 10.5 months. In addition, a dynamic lagoon-temperature (Tw) model from the literature was modified in its terms of solar radiation and aeration latent heat, and applied to the primary lagoon. The model was fed with the estimated influent temperature, and five model parameters were identified by calibration against 10.5-month Tw data. Dynamic lagoon-temperature estimation results were comparable to or better than other results of long-term simulations found in the literature. Sensitivity analyses were run on both models. Further validation with independent sets of data is needed for verification of the predictive capability of the models.
