“…Over that time studies have been performed, either in the laboratory or at actual WWTPs on the role of Archaea in oxidation of ammonia and removal of nitrogen compounds [12,13]. However, significant differences in sludge biocoenosis and a large genetic diversity of both AOA and AOB were observed among the WWTPs [10,14,15].…”

The use of Archaea in the bioaugmentation of activated sludge as a method for the biological removal of nitrogen compounds Wykorzystanie archaea w bioaugmentacji osadu czynnego jako metody biologicznego usuwania związków azotu Abstract This paper examines the effect of Archaea on wastewater treatment in sequencing biological reactors (SBR).The research was carried out in two SBR reactors: a reactor with activated sludge bioaugmented with Archaea (microorganisms which constitute a third domain besides Bacteria and Eukaryotes); a reactor with conventional activated sludge was used as a control. Archaea were incubated in laboratory conditions as recommended by Archaea Solutions Inc. The research revealed that the time period required for the acclimation of the activated sludge in the presence of Archaea was twice as long as in the case of regular nitrifying activated sludge. The observed nitrogen and phosphorous removal from wastewater was achieved to a higher extent in sludge with Archaea and the sludge itself settled faster. The required concentration of oxygen in the reactor with Archaea was lower than in the classic set-up -this resulted in lowering the operating costs of the treatment plant. Furthermore, the denitrification process was significantly shorter and did not require nitrate nitrogen (V).

“…The genera Salmonella, Shigella, Escherichia, Klebsiella, Serratia, Enterobacter and Proteus are most commonly found in municipal sewage and therefore detected in bioaerosols (Grisoli et al 2009, Kacprzak et al 2005, Korzeniewska et al 2009, Ławniczek-Wałczyk et al 2018. In recent years, there have been numerous reports on the presence of Archaea in the biocoenosis of activated sludge (mainly the genera Halobacterium and Methanolobus), hence their presence in bioaerosols from sewage treatment plants can be expected, however the risk to their exposure remains unknown (Anielak et al 2015).…”

In this work microbiological air pollution at several commune sewage treatment plants (capacity up to 15,000 PE) was investigated. The bioreactors in all plants had a covered construction. The air samples were taken indoors as well as outdoors (both on the windward and leeward side) during different seasons. The samples were collected using the collision method. The presence of indicator organisms in the samples was determined according to the Polish Standards. Identifi cation of individual indicators was performed on solid selective--differentiating substrates. To verify the presence of bacteria from Salmonella, Shigella, coliforms and enterococci species, the colonies observed on the MacConkey substrate were then sifted onto SS and Endo substrates. At all facilities (with one exception) the average CFU for the total number of bacteria and fungi did not exceed 1000/m 3 , which is the limit set by the Polish Standards for a pollution-free atmospheric air. Bacteria and fungi concentrations, observed at windward and leeward sides of all plants, were relatively low (<100 CFU/m 3 and <1000 CFU/m 3 , respectively) and comparable. A sewage collection point had only a slight impact on the bioaerosol emission. The concentration of microorganisms in the immediate vicinity of covered reactors (aeration chambers) was rather low and remained below the limits sets by the Polish Standards at three facilities. The CFU of individual indicators, measured in rooms accessible for the personnel, was comparable to the CFU in technological rooms. However some indicators, e.g. a number of Actinomycetes, were signifi cantly higher and reached >100 CFU/m 3 , which means signifi cant air pollution. Similarly, the CFU of hemolytic bacteria had nonzero values. The only place where higher concentrations of bioaerosol were found was the centrifuge room, where digested sludge was dewatered. The number of fungi stayed below the limits there, but the amount of heterotrophic and hemolytic bacteria exceeded the limits and reached the values of ~10000 CFU/m 3 and 800 CFU/m 3 , respectively; it means that the personnel working in this area is exposed to microbiological agents.

The aim of this study was to evaluate the effect of bioaugmentation with Archaea domain organisms on the activated sludge (AS) expressed by the oxygen uptake rate (OUR) in a laboratory sequencing batch reactor (SBR). The influence of depletion of the external substrate in bioaugmented (SBR-A) and non-bioaugmented (SBR-B) activated sludge during aerobic stabilization was investigated. The experiment was divided into two steps. First, the OUR was measured in the standard conditions of biological treatment. Second, AS was only aerated in the absence of the substrate. It was observed that bioaugmentation with Archaea had an increasing effect on the endogenous and exogenous OUR of the sludge in both phases. In the first phase, the average endogenous OUR was 28.70 ± 2.75 and 21.63 ± 0.9 mgO2·dm−3·h−1 in the SBR-A and SBR-B, respectively. Regarding the exogenous OUR, the average values were 95.55 ± 11.33 and 57.15 ± 24.56 mgO2·dm−3·h−1 for the SBR-A and SBR-B, respectively. Archaea enhancing its biological activity, expressed as the OUR, exert a stabilizing effect on this parameter of AS and ensure its lower sensitivity to changes in the process conditions, substrate supply disruption and prolonged aeration.
