The Study of Some Bioaerosols (Bacterial) Pollution in Air of Wastewater Treatment Plant in Cold Months
Abstract
Numerous pathogenic and non-pathogenic microorganisms are present in the wastewater. These bacteria have the potential to transform into bioaerosols throughout the treatment process, endangering the health of plant employees. The results of the study showed the highest mean number of bacteria (mean 150.0 CFU CFU/m3) in November was observed in the aeration tank and the minimum mean number of bacteria (mean 4.0 CFU/m3) was in February in the site from 100 m, distant from the plant, The majority of the air of the station was negative bacteria, and the proportion of Enterobacteriaceae was (50.4%). harmful bacteria, such as (Aeromonas sp., Klebsiella pneumoniae sp., Acinetobacter sp., Pseudomonas sp., and others) can cause risk impact on the employees in plant.
