With the exception of the first three influent applications and in contrast with clay loamy soil treatments (B0, B5, and B10), the loamy sand soil treatments could not adsorb Pb2+.
The aerobic bacterial respiration rate is an indicator of microbial growth and metabolism, essential for monitoring the oxidation process and organic load content of samples in a diverse field of application from influent streams in wastewater treatment facilities to industrial fermentations.
The CEC of the loamy sand soil and zeolite were saturated with cations and anions such as Na+, Ca2+, Cl−, which existed in the influent upon first leachate applications.
The orange dashed lines indicate influent concentrations when applicable.
Ongoing application of out-dated influent values as part of development assessment processes could potentially provide inaccurate results, incorrectly sized and under-performing treatment measures.
The application of the proposed influent generator to the Eindhoven WWTP shows that it is a powerful tool for realistic generation of influent time series and is well-suited for probabilistic design of WWTPs as it considers both the effect of input variability and total model uncertainty.
Black-box, stochastic grey-box and hybrid models are useful in WWTP applications for prediction of the influent load, for estimation of biomass activities and effluent quality parameters.
In addition, the influent was switched from synthetic wastewater to domestic wastewater to examine the key parameters for the application of HAB.
Regarding the actual application of biosurfactants in bioremediation processes the molecules may either be added externally (i.e., influent, spraying, injection) or produced on-site, which seems especially promising in case of in situ treatment.
