Opis:
The paper describes the status of water supply and sanitation infrastructure in the Kraśnik County. The description is based on the official statistical data and the data obtained in a survey carried out in 2016. The Kraśnik County is located in the Lublin Province and comprises 10 communes: one urban commune (the Municipality of Kraśnik), two urban-rural communes (Annopol and Urzędów), and seven rural communes (Dzierzkowice, Gościeradów, Kraśnik, Szastarka, Trzydnik Duży, Wilkołaz, and Zakrzówek). In 2016, an average of 90.9% of the County’s inhabitants had the access to the mains water, but only 13.5% were connected to the mains sewerage. The County has six centralized wastewater treatment plants with a total capacity of approximately 14.164 m3/d. The survey data showed that the records of cesspools were kept in only four of the County’s communes: the Municipality of Kraśnik, Urzędów, Wilkołaz, and Zakrzówek. The total number of cesspools in those communes was 4776. The Kraśnik County is in great demand for the construction of on-site domestic wastewater treatment plants, which are an excellent alternative to cesspools. The network of domestic wastewater treatment plants in the Kraśnik County is made up almost entirely of systems with a drainfield, which may pose a serious threat to the soil and water environment. The results of the present study suggest that Commune Offices must take decisive steps to eliminate the existing disproportion between the coverages of the sewerage and water supply systems in the County’s communes.

Opis:
Sewage-treatment plants generate sludge which needs to be neutralized for legal, esthetical, and practical reasons. Economical and ecological concerns indicate that sludge, as long as it is possible, should be returned to the natural environment. The article presents the process of autothermal thermophilic aerobic digestion (ATAD) as a measure to produce biomass, which can be naturally utilized. The description of theoretical principles of the process in question is accompanied by presentation of an ATAD installation which has been functioning since 2009 at the municipal sewagetreatment plant in Olecko. Results of microbiological and chemical tests carried out in the years 2010–2012 have been analyzed. Examinations embraced sludge which was the final product of the aforementioned sewage-treatment plant.

Opis:
The article presents research on the assessment of electrolytic conductivity changes of sludge during the process of its autothermal thermophilic aerobic digestion (ATAD), which takes place in a two-stage installation system, operating in a municipal sewage-treatment plant. In the years 2012–2014 sludge was studied and the results were analyzed. Thickened sludge in the intermediate tank, which was then directed to installation reactors, was examined. Conductivity was measured in each tank. In this manner collected results made it possible to follow the changes of this index at consecutive stages of the system. The results were statistically analyzed and it was determined to what degree, as a result of an objective process, the values of processed sludge conductivity would change. The conclusions from the carried-out studies and from own experiments are also presented.
