1. Introduction. Wastewater contains large numbers of microorganisms, which may be aerosolized into the surrounding air and generating airborne bacteria during wastewater and sludge treatment processes (Lin and Marr, 2017; Uhrbrand et al., 2017).Numerous studies have investigated the concentration, particle size distribution, and communities of airborne bacteria generated in different stages
Bacterial air pollution at a wastewater treatment plant
An investigation of bacterial aerosols emitted from aeration tanks at an activated sludge wastewater treatment plant was conducted by Niagara University undergraduates as a way to explore local microbial issues and their effects on society. Ambient air concentrations of bacteria were measured upwind and downwind of the aeration tanks, and any downwind increase was attributed to the tanks. The

Assessment of bioaerosol contamination (bacteria and fungi
Bioaerosol concentration was measured in wastewater treatment units in south of Tehran, the largest wastewater treatment plant in the Middle East. Active sampling was carried out around four operational units and a point as background. The results showed that the aeration tank with an average of 1016 CFU/m3 in winter and 1973 CFU/m3 in summer had the greatest effect on emission of bacterial
The objective of this study was to assess exposure to anaerobic bacteria released into air from sewage and sludge at workplaces from a wastewater treatment plant (WWTP). Samples of both sewage and sludge were collected at six sampling points and bioaerosol samples were additionally collected (with the use of a 6-stage Andersen impactor) at ten workplaces covering different stages of the
Bacteria or Enzymes for Wastewater Treatment? Pollution
Onsite wastewater treatment with a bacteria product like NCH Europe’s FreeFlow will digest the decaying fat and food waste, eliminating the problem completely. Bacteria may sound like something you would want to keep far away from food production, but products like FreeFlow are non-hazardous, non-GM and food safe.
Cleveland Biotech (UK) developed The Baccelerator in conjunction with a leading Water Company almost three years ago – and the product is proving as popular as ever with an upsurge of companies requesting its services. Click to read more...
Microplastics and Wastewater Treatment Plants—A Review
The emission of microplastics into nature poses a threat to aquatic and terrestrial ecosystems. Their penetration of the food chain presents a danger to human health as well. Wastewater treatment plants can be seen as the last barrier between microplastics and the environment. This review focuses on the impact of waste treatment plants in retaining microplastics.
