Results of a study conducted to assess the degree of airborne microbial contamination generated by a wastewater treatment plant (WWTP) with bioreactor "BIO-PAK" closed treatment system and evaluation of the dispersion of potential pathogens are described. Over the year aerosol samples were collected simultaneously with sedimentation and impact methods from(More)
Wastewater treatment plants affect the environment in many different ways. It can be assumed that the intensity and range of microbiological emission is the crucial factor in determining the range of restrictedusage zone. This paper presents emission levels of microbiological pollutants from the wastewater treatment plant in Bartoszyce, Poland. It is a new(More)
A study into the removal of contamination load and indicator bacteria was carried out in 1992-1996 in the mechanical, biological and chemical waste-water treatment plant WTP in Lezany, in the County of Reszel, in the Province of Warmia and Mazury in Poland. The results of chemical analyses found a high efficiency of removal of carbon compounds, COD (90%)(More)
The study was carried out on the survival of Escherichia coli and Aeromonas hydrophila in samples of mineral waters. Enumeration of the bacteria was performed by spread inoculation of samples (0.1 cm3) over the surface of selected media in Petri plates. Twenty bottles (four bottles of each of the five brands) of non-carbonated mineral waters with different(More)
The microbiological quality of five brands of carbonated and non-carbonated mineral water sold in Poland was studied. The study was carried out on the survival of heterotrophic bacteria at 22 and 37 degrees C (pour plate technique) in the samples of mineral waters stored at 4 and 22 degrees C. The one hundred ten bottles (twenty two bottles of each of the(More)
This work describes bacteriological studies on the quantitative and qualitative composition of bacteria from the family Enterobacteriaceae as well as numbers of Pseudomonas aeruginosa and Aeromonas hydrophila in underground waters of the Omulewski Reservoir, a source of water for consumption. In 1994-1995 studies were carried out on 11 deep wells and 3(More)
