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 ...
Mathematical Modeling of Thermal Drying of Facultative Pond Sludge
(Asce-amer Soc Civil Engineers, 2018-09-01)
This study investigated the sludge drying from a facultative pond in a dryer that employs two dehydration methods: thermal drying by infrared lamps and convective drying. For the tests, three thicknesses of sludge were ...
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 ...
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 ...
Use of Primary Sludge from Pulp and Paper Mills for Nanocomposites
(Taylor & Francis Ltd, 2012-01-01)
Cellulose nanocrystals have been evaluated as reinforcement material in polymeric matrices due to their potential to improve the mechanical, optical, and dielectric properties of these matrixes. This work describes how ...
