Opis:: The sludge management of many wastewater treatment plants in Poland has not been properly solved yet. The exploiters and designers often have to cope with the dilemma of choosing the method of processing and neutralizing sewage sludge. The method discussed in the article is only one of the options that fully fits in the trends of implementing good practices in the management of sewage sludge. It is a technologically and economically effective as well as environmentally friendly process. It contributes significantly to minimizing the amount of sewage sludge and allows the production of organic fertilizer instead of waste. The work discusses the quality of sewage sludge after autothermal thermophilic stabilization (ATAD). The results of investigations pertaining to the reaction of sludge, dry mass, dry organic matter, content of biogenic substances, calcium and magnesium compounds and heavy metals were analyzed.

Tytuł:: Sludge as an agent improving soil properties

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:: In the study the physicochemical properties of selected municipal sewage sludge were compared using the reports on waste generation from the years 2007–2012 in the Mazovia voivodship. The selection was done on the basis of different methods of sludge processing and the number of equivalent inhabitants (NEJ) supported by sewage. Physical and chemical properties of municipal sewage sludge were significantly dependent on the method of purification and treatment methods. These sludges were characterized by a high content of organic matter and macronutrients. The amount of heavy metals (Pb, Cd, Cr, Cu, Ni, Hg and Zn) were within acceptable standards for municipal sewage sludge used in agriculture. Municipal sewage sludge treated by biological method with higher nutrients removal did not create bacteriological danger and were used in agriculture, generally to the cultivation of all agricultural products. Sewage sludge sanitized with lime and subjected to anaerobic digestion did not meet bacteriological standards, which eliminated their use in agriculture.

Tytuł:: Utilization of Sewage Sludge after the Process of Autothermal Digestion

Opis:: Sediments constitute one of the wastes that are generated in sewage treatment plants. The methods of their final management depend on the sewage sludge system management. One of the employed methods is Autothermal Thermophilic Aerobic Digestion (ATAD). The article presents the process of autothermal oxygen digestion of sewage sludge as a method enabling to obtain biomass, which can be used in the natural environment. In addition to the description of the theoretical basis of the discussed process, the quality of the formed sewage sludge is presented. The amount of sludge and the manner of its final utilisation were also analyzed. The results were presented on the basis of waste records kept in each of the analyzed sewage treatment plants. Sludge transfer cards in 2013-2018 were also analyzed in the sewage treatment plants where sludge undergoes the ATAD process.
