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 ...
Microbial populations and activities in sewage sludge and phosphate fertilizer-amended soil
(Elsevier B.V., 1996-07-01)
A greenhouse study was conducted to determine the number of microbial populations and activities in sewage sludge and phosphate fertilizer-amended dark red latosoil for cultivation of tomato plants. Sewage sludge was applied ...

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 ...
Use of municipal and industrial sludge in agricultural soil: Responses of soil microbials and soil enzymes
(2009-04-01)
Industrialization has contributed to the increase in the generation of potentially toxic solid residues. Textile and tannery industries produce residues, called sludge, with high organic and inorganic content, including ...
Characteristics of WWTP sludge after drying in greenhouse for agricultural purposes
(IWA PUBLISHINGLONDON, 2012)
The sludge generated by sewage treatment which meets regulatory standards can be used in agriculture. With this understanding, the focus of this study is the evaluation of the agricultural characteristics and inorganic ...
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 ...
