Removal of heavy metals from anaerobically digested sewage sludge by isolated indigenous iron-oxidizing bacteria.
The removal of heavy metals (Cr, Cu, Zn, Ni and Pb) from anaerobically digested sludge from the Yuen Long wastewater treatment plant, Hong Kong, has been studied in a batch system using isolated indigenous iron-oxidizing bacteria. The inoculation of indigenous iron-oxidizing bacteria and the addition of FeSO4 accelerated the solubilization of Cr, Cu, Zn, Ni and Pb from the sludge. pH of the slu...
متن کاملAeration of anaerobically digested sewage sludge for COD and nitrogen removal: optimization at large-scale.
The paper will report about the experiences at an Austrian large wastewater treatment plant of 720,000 population equivalents, where anaerobically digested sewage sludge is further stabilised under aerobic conditions. Enhanced stabilisation of the anaerobically digested sludge was required at the plant in order to get a permit for landfill disposal of the dewatered stabilized sludge. By impleme...
متن کاملDecomposition of Fresh and Anaerobically Digested Plant Biomass in Soil
Using water hyacinth [Eichhornia crassipes (Mart.) Solms) for wastewater renovation produces biomass that must be disposed of. This biomass may be anaerobically digested to produce CH4 or added to soil directly as an amendment. In this study, fresh and anaerobically digested water hyacinth biomass, with either low or high N tissue content, were added to soil to evaluate C and N mineralization c...
متن کاملBiological testing of a digested sewage sludge and derived composts.
Aiming to evaluate a possible loss of soil habitat function after amendment with organic wastes, a digested sewage sludge and derived composts produced with green residues, where biologically tested in the laboratory using soil animals (Eisenia andrei and Folsomia candida) and plants (Brassica rapa and Avena sativa). Each waste was tested mimicking a field application of 6ton/ha or 12ton/ha. Av...
متن کاملSignificance of Vivianite Precipitation on the Mobility of Iron in Anaerobically Digested Sludge
Anaerobic digestion requires a balanced availability of micro-nutrients with ideal growth conditions to reach optimal organic degradation and biogas production. Iron is the most abundant of the essential metals in an anaerobic digester and its mobility has a strong impact on microorganisms through its own bioavailability, but also through its influence on the bioavailability of other metals. Mo...
