Dependence between quality and removal effectiveness of organic matter in hybrid constructed wetlands
W procesie oczyszczania ścieków w Vertical Flow Constructed Wetland (VF-CW) jednym z czynników jest dopływ tlenu. Niewystarczający dopływ tlenu do złoża może być przyczyną braku efektywności usuwania zanieczyszczeń, a więc wskazywać na niewłaściwą eksploatację obiektu.Obiekty badań stanowiły złoża pionowe stanowiące jeden z elementów biologicznego oczyszczania dwóch hybrydowych systemów hydrofitowych zlokalizowanych w Wieszynie...

Potential fertilizing properties of sewage sludge treated in the Sludge Treatment Reed Beds (STRB)
In research the fertilizer value of sludge from reed beds is evaluated based on the sampling sludge on different depths from 4 Danish STRB after long periods of stabilization. The dewatering efficiency of sewage sludge in the STRB is comparable to mechanical dewatering. The long-term stabilization of sewage sludge progressively decreases the concentration of organic matter due to the process of humification. The aim of the work...

Integrated dewatering and stabilization system as an environmentally friendly technology in sewage sludge management in Poland
Sludge treatment reed beds (STRBs) are an environmentally friendly technology which provides integrated dewatering and stabilization of sewage sludge. STRBs do not require the use of chemicals to improve the dewatering process. STRB is both, a low-emission and a low-energy-consuming method. After the stabilization process, sludge is characterized by the chemical composition similar to that of humus. The aim of the paper is to present...
