Stabilization of mechanically biologically treated waste in anaerobic, aerobic and semi-aerobic bioreactors

Waste Management & Research: The Journal for a Sustainable Circular Economy, 2021
The study aims to investigate the application of anaerobic (AN), aerobic (AER) and semi-aerobic (SA) laboratory scale landfill bioreactors for stabilization of mechanically and biologically treated (MBT) waste of Bangalore city. All major parameters pertaining to the waste, leachate and biogas are continuously monitored during the experiment.

Kinetics of aerobic sludge stabilization

Water Research, 1972
Abstract The aerobic decomposition of organic sludge solids, measured in volatile solids and bacterial mass (respiration rate, acetate decomposition activity) has been determined at different temperatures ( Tables 1 and 2). Based on the rates of respiration (which is directly proportional to the reaction constant of decomposition) the ...

Aerobic Sludge Stabilization—Factors Affecting Kinetics

Journal of Environmental Engineering, 1989
The effects of temperature, pH, sludge age in the prior activated sludge process, initial sludge solids concentration, and sludge type on the rate of solids degradation during aerobic sludge stabilization are discussed. Primary sludge (PS), waste activated sludge (WAS), and mixed primary and waste activated sludges (PS/WAS) are stabilized.

Aerobic and Anaerobic Landfill Stabilization Process

Journal of the Sanitary Engineering Division, 1970
A series of laboratory investigations was performed to replicate the aerobic and anaerobic sanitary landfill environment. The oxygen demand of solid waste was found to be directly proportional to the amount of easily utilizable organics present in the test material.

Postural Stability in Aerobic Gymnastics Specific Positions

Sport Science Review, 2010
Postural Stability in Aerobic Gymnastics Specific Positions The study compares the effect of maximal jumps and sport-specific exercises on parameters of balance. Two balance elements (free support vertical split and frontal split) were analyzed in a group of 8 aerobic gymnasts (average age = 17,0 ± 1,3 years, average body height = 163,0 ± 6,9 ...

Respirometric assessment of aerobic sludge stabilization

Bioresource Technology, 2010
Aerobic sludge stabilization was assessed respirometrically with the sludge taken from the secondary settling tank of a domestic wastewater treatment facility in Istanbul, Turkey. Zero-order removal rates of 178, 127 and 44 mg/L day were found for Suspended Solids (SS), Volatile Suspended Solids (VSS) and Total Organic Carbon (TOC) at the end of 18 ...

Effect of Rotifers on the Stability of Aerobic Granules

Environmental Technology, 2007
The current study evaluated the effect of rotifers on the stability of aerobic granules. Two sequence batch reactors (SBRs) with airflow rates of 4 (R1) and 6 (R2) 1 min(-1), respectively, were used to develop aerobic granules. Granules were well developed with excellent settleability in terms of SVI30 (sludge volume index,) of about 50 ml g(-1) in ...

Stability of aerobic granules during long-term bioreactor operation

Biotechnology Advances, 2018
Aerobic granular sludge technology has been extensively studied over the past 20 years and is regarded as the upcoming new standard for biological treatment of domestic and industrial wastewaters. Aerobic granules (AG) are dense, compact, self-immobilized microbial aggregates that allow better sludge-water separation and thereby higher biomass ...

Localization and stability of hydrogenases from aerobic hydrogen bacteria

Archives of Microbiology, 1977
Alcaligenes eutrophus strains H 16, B 19, G 27 and N9A contained two different hydrogenases. One enzyme catalyzed the reduction of NAD by hydrogen and was strictly localized in the soluble cell fraction. While the second enzyme was found to be particulate and unable to react with NAD.

Effects of Corn Silage Inoculants on Aerobic Stability

2002 Chicago, IL July 28-31, 2002, 2002
Aerobic stability of corn silage can be a major problem for farmers particularly in warm weather. Silage inoculants, while the most common type of silage additive, have not been effective at improving aerobic stability. This study investigated new and proposed inoculant products over three years on corn silage in mini-silos.
