Sludge dewatering reed beds and their performance in terms of sludge quality improvement at small wastewater treatment plants

Popis výsledku v původním jazyce

Wastewater treatment sludge presents a significant problem for small wastewater treatment plants due to the high costs of the final handling process and the need to solve the various technological problems involved. To date, the Czech Republic has little experience of Reed Bed technology. This study focused on the testing of two pilot RB systems of different construction installed at two small WWTP – a constructed wetland in the Southern Moravia region for 800 PE and an activated sludge treatment plant in the Central Bohemian region for 1900 PE. The two pilot reed beds were filled with liquid sludge containing between 2 to 13 % of total solids (TS). Both of the pilot units evinced very promising results in terms of the extensive dewatering of the sludge by up to 30–34 % of the TS in average at the end of each campaign. At the end of the study period, it was observed that the content of pathogenic microorganisms and other monitored substances did not exceed Czech limits for agricultural use.
