Water Treatment Plant Sludge Discharge to Wastewater Treatment Works: Effects on the Operation of Upflow Anaerobic Sludge Blanket Reactor and Activated Sludge Systems
(WATER ENVIRONMENT FEDERATION, 2010)
This experiment examined the effects of the discharge of water treatment plant (WTP) sludge into the following three types of wastewater treatment systems: a pilot-scale upflow anaerobic sludge blanket (UASB) reactor, a ...
Hexavalent chromium removal using aerobic activated sludge batch systems added with powdered activated carbon
(Water Research Commission, 2009-12)
The addition of powdered activated carbon (PAC) has been proposed as a suitable technique to protect activated sludge against toxic wastewaters. However, the literature data describing the combined effect of PAC addition ...
Evaluation of the recirculation process of aerobic sludge from a percolating biological filter in an upflow anaerobic sludge blanket digestion reactor, with characterization of sludge solids
(2021-09-01)
In this work, the sustainability indicators from a sewage treatment plant in a Southern Brazilian city, with a combined system of anaerobic treatment by upflow anaerobic sludge blanket (UASB) reactor and aerobic treatment ...
Fenton oxidation as a strategy to preserve the biomass in the activated sludge system
(Planta Piloto de Ingeniería Química, 2020-02)
Wastewaters containing biocides constitute an increasing environmental pollution concern. In this work, the feasibility of implementing a pretreatment based on the Fenton process to minimize the negative impact of biocide ...
Industrial activated sludge exhibit unique bacterial community composition at high taxonomic ranks
(Elsevier, 2013-04-17)
Biological degradation of domestic and industrial wastewater by activated sludge depends on a common process of separation of the diverse self-assembled and self-sustained microbial flocs from the treated wastewater. ...
