A result of the project Possibilities of using sewage sludge as a secondary source of phosphorus in the Czech Republic is a comprehensive study mapping not only the phosphorus content but also the degree of contamination of sewage sludge from various types of wastewater treatment plants in the Czech Republic. This study represents a basis for planning site-specific strategies for the use of phosphorus from sewage sludge in the Czech Republic. Six basic steps led to the elaboration of the study: analysis of the WWTP network in the Czech Republic (1), repeated sampling, analysis of sludge and evaluation of sludge properties of sludges collected from selected facilities representing typical representatives of the nature of source areas and wastewater treatment and sludge treatment technologies (2), legislative analysis of the future of sewage sludge management (3), tests of thermal treatment of sludge and their evaluation (4), search of available technological solutions for sludge treatment (5) and proposal of the concept of sludge treatment in the Czech Republic (6).
