“…Both methods have been extensively used and applied to characterize stormwater, sewage, and wastewater along the WRRFs treatment chain. Moreover, their reliability and reproducibility have been proven (Bachis et al, ; Berrouard, ; Maruéjouls, Lessard, & Vanrolleghem, ). In this case, no sample pretreatment was applied to not modify the raw sample and to not loose any particles.…”

Grit chambers are installed at the headworks of a water resource recovery facility (WRRF) to reduce the impact of grit particles to the equipment and processes downstream. This settling process should thus be designed and operated in an efficient way. Despite the importance of knowing settling characteristics for design and operation of grit chambers, previous grit definitions have been based only on particle size characteristics, and not on settling velocities. Thus, this study presents an evaluation of the performance of two promising settling velocity characterization methods, ViCAs and elutriation, to characterize wastewater particles in view of the design and the optimization of the efficiency of the grit removal unit. © 2019 Water Environment Federation • Practitioner points• Settling characteristics are the governing parameter for grit chamber design. Since grit particles are vastly heterogeneous, it is preferred to measure these characteristics directly rather than to estimate them from particle size (and assumptions of density, form factor, …). • More detailed settling information about grit particles can improve grit chamber design and estimation of removal performance. • Adapted ViCAs and elutriation methods for faster settling particles allow studying the particle settling characteristics in a grit chamber. These methods are simple, fast, and cheap and only require small wastewater samples. • A relationship was found between the influent TSS concentration and the location of the PSVD curve, with higher TSS concentrations corresponding to higher settling velocities. • It was demonstrated that the dynamics of the wastewater characteristics under dry, wet, and snowmelt weather conditions influence grit settling characteristics.

“…All the studies in the reviewed papers regarding biomarkers or microorganisms focused on revealing their degradation or growth processes, as shown in Table 2 (Thai et al 2014, Ai et al 2016. For PPCPs, FOG, TSS, BOD, their concentrations within SNs or in their overflows were predicted and the utility of the controlling strategies (e.g., mineralization, pump operations, changing of pH, retention tanks) assessed with the aid of models (Maruejouls et al 2014, Nieuwenhuis et al 2018.…”

“…They illustrated that small differences in V6 sequences can represent phyloge-netically and ecologically distinct taxa and they provided an insight into microbial community composition and dynamics within the defined environment of urban sewer infrastructure. The ViCAs settling test was used to im-prove the understanding of the pollutant dynamics and their interactions in Canada [43]. They developed full-scale field data sets where the results show a good agreement between observed and simulated data both for the total suspended solids and the total chemical oxygen demand.…”

“…They concluded that it was particularly useful because many visible aspects of Japanese environmental management are not those that are rationally based on paradigms of decision making, which would be associated with environmental improvement and resilience. Phylogenetic trees and UniFrac analysis were used to evaluate the population structure and temporal dynamics of the dominant community members within sewage influent from two wastewater treatment plants (WWTPs) in Milwaukee, WI [43]. They illustrated that small differences in V6 sequences can represent phyloge-netically and ecologically distinct taxa and they provided an insight into microbial community composition and dynamics within the defined environment of urban sewer infrastructure.…”

The sewer system of many historical or holy cities is not well associated with the present need. The managing of the sewer system of such cities is very difficult. Karbala, located in central Iraq, is one such city that experiences tremendous pressure on its sewer system due to large visiting population during special religious gathering. As the sewer system of Karbala city is not designed for such high population like many other historic or holy cities, the sewer overflows, inundate the roads, and degrade the environmental due to the polluted sewer during religious gatherings. The problem often becomes critical due to heavy rainfall as the gathering usually happens during monsoon. The modeling of the sewer water quantity with a varying population and rainfall is important for simulating the sewer overflow as well as to manage the sewer system. The modeling of the sewer water quality is also important to understand the possible environmental hazard due to the sewer overflow. In this present study, an attempt has been taken to simulate the spatiotemporal distribution of the sewer water quantity and quality with a varying population and rainfall for the prediction of sewer overflow and possible pollution susceptibility. The Stormwater Management Model (SWMM) will be used in the proposed study. The simulation will be carried out in the city center of the Karbala city where the stormwater network is not fully developed. It is expected that this study will help in the operational management of the sewerage system and mitigate the sewer flooding and related environmental problems.
