“…From these data, the authors were able to demonstrate that the main odor sources of a WWTP were found among the pretreatment units, specifically at the primary sedimentation step, and that, generally, the odor emission tended to decrease along the depuration cycle [67]. This behavior has also been observed by other authors, who also correlated these higher odor emissions at pretreatment units with an increased presence of H 2 S, NH 3 , and different VOC families with a low odor detection threshold such as VSCs or ketones [66,68,69]. Recently, De Sanctis et al ( 2022) assessed the impact of implementing MULESL technology (MUch LEss SLudge; patent WO2019097463), which aims to reduce sludge generation and the discharge of contaminants of emerging concern (CEC) when treating part of the inlet wastewater from Putignano's WWTP.…”

“…In open-to-air WWTP, pretreatment units, primary settlers, biological aerated reactors, or the sludge treatment (dewatering, anaerobic digestion, etc.) can be effective emissions sources [66]. Accordingly, typical odor collection devices must be adapted (Figure 2).…”

“…Although H 2 S removal is properly accomplished by biofilters, biotrickling filters, and activated carbon adsorbers, fluctuating loads and the presence of other odorants make selection complex. Often a combination of different configurations in-series is an appropriate alternative [66,80].…”

“…However, several authors have shown that either converting chemical scrubbers to BTFs for VICs' removal [90,98], combining a BTF followed by a biofilter for complex odorants abatement at WWTP [66], or even using in-series BTFs for S-compounds' removal may be also effective for biobased-only odor abatement, while, at the same time, a much more sustainable and economical alternative [99].…”

In recent decades, a new generation of waste treatment plants based on biological treatments (mainly anaerobic digestion and/or composting) has arisen all over the world. These plants have been progressively substituted for incineration facilities and landfills. Although these plants have evident benefits in terms of their environmental impact and higher recovery of material and energy, the release into atmosphere of malodorous compounds and its mitigation is one of the main challenges that these plants face. In this review, the methodology to determine odors, the main causes of having undesirable gaseous emissions, and the characterization of odors are reviewed. Finally, another important topic of odor abatement technologies is treated, especially those related to biological low-impact processes. In conclusion, odor control is the main challenge for a sustainable implementation of modern waste treatment plants.

“…The results show that the average highest emission rate was recorded in the primary settling tank (approx. 200 g/min), while for the other facilities, this parameter was much lower (grit chamber—26 g/min, raw wastewater receiving tank about 8.67 g/min, screens—6.33 g/min, aeration chamber in MBR reactor—4.5 g/min) [ 70 ].…”

Using Poland as an example, it was shown that 41.6% of the requests for intervention in 2016–2021 by Environmental Protection Inspections were related to odour nuisance. Further analysis of the statistical data confirmed that approximately 5.4% of wastewater treatment plants in the group of municipal facilities were subject to complaints. Detailed identification of the subject of odour nuisance at wastewater treatment plants identified hydrogen sulphide (H2S), ammonia (NH3) and volatile organic compounds (VOCs) as the most common malodorous substances within these facilities. Moreover, the concentrations of hydrogen sulphide and ammonia exceed the reference values for some substances in the air (0.02 mg/m3 for H2S and 0.4 mg/m3 for NH3). A thorough assessment of the properties of these substances made it clear that even in small concentrations they have a negative impact on the human body and the environment, and their degree of nuisance is described as high. In the two WWTPs analysed in Poland (WWTP 1 and WWTP 2), hydrogen sulphide concentrations were in the range of 0–41.86 mg/m3 (Long-Term Exposure Limit for H2S is 7.0 mg/m3), ammonia 0–1.43 mg/m3 and VOCs 0.60–134.79 ppm. The values recognised for H2S cause lacrimation, coughing, olfactory impairment, psychomotor agitation, and swelling of the cornea with photophobia. Recognition of the methods used in practice at WWTPs to reduce and control malodorous emissions indicates the possibility of protecting the environment and human health, but these solutions are ignored in most facilities due to the lack of requirements specified in legislation.
