Monte Carlo simulations of the transformation and removal of Ag, TiO2, and ZnO nanoparticles in wastewater treatment and land application of biosolids

Application of the Mathematical Simulation Methods for the Assessment of the Wastewater Treatment Plant Operation Work Reliability

“…Finally, statistical analysis of the obtained results is performed. As some papers show [43], the Monte Carlo method is commonly used for the analysis of water and sewage management facilities operation work. It should be emphasized that the Monte Carlo method has some advantages and disadvantages.…”

Heteroaggregation, transformation and fate of CeO2 nanoparticles in wastewater treatment

“…In comparison to other metal-based, wastewater transformed ENMs including Ag and ZnO, CeO 2 NPs do not undergo complete transformation in WWTPs, indicating that more native NP species will accumulate in wastewater solids. As noted in previous studies, estimates of the concentrations of ENM-based material released from WWTPs are highly sensitive to the assumptions made regarding production quantities and NP concentrations entering the WWTP, in addition to the measured distribution coefficient (Barton et al, 2015). …”

“…The Monte Carlo modeling effort used in this work builds on a model for wastewater treatment and removal of Ag, ZnO, and TiO 2 NPs described elsewhere (Barton et al, 2015). This model expands on the work of Hendren et al (2013) modeling aerobic treatment to include simple descriptions of both aerobic and anaerobic treatment and redox transformations of NPs that may occur in the sewer system, primary treatment, secondary treatment, and anaerobic digestion.…”

SERENADE: safer and ecodesign research and education applied to nanomaterial development, the new generation of materials safer by design

“…These transformed NPs are more thermodynamically stable. [27][28][29][30] The influence of the coating was found to be very important in terms of the affinity of NPs for bacteria present in the sludges. Using a laboratory reactor with activated sludge in aerobic mode, the affinity of bare and coated industrial CeO 2 NPs for bacteria was measured.…”
