Effects of Corn Silage Inoculants on Aerobic Stability
2002 Chicago, IL July 28-31, 2002, 2002Aerobic 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.

A laboratory study on stabilization criteria of semi-aerobic landfill
Waste Management & Research: The Journal for a Sustainable Circular Economy, 2008The semi-aerobic landfill has been widely used as a sustainable landfill technology. However, the stabilization indicator system and stabilization criteria of semi-aerobic landfill have not been developed yet. In this study, the stabilization indicator system and stabilization criteria of semi-aerobic landfill were studied on the ...

Enhanced storage stability of aerobic granules seeded with pellets
Bioresource Technology, 2010The responses of two different types of aerobic granules to storage, granule A seeded with activated sludge flocs and granule B seeded with pellets (cells), were investigated in this study. After 3-week storage, the surface of granule B remained compact and smooth while obvious crevices were observed on that of granule A.

Laboratory studies of aerobic stabilization of swine waste
Journal of Agricultural Engineering Research, 1966Pig waste was allowed to accumulate in a pit beneath a slatted-floor swine finishing building for one week or one month. Samples of this waste were brought to the laboratory for analysis and aerobic stabilization. It was concluded that adding the raw waste continuously to the aeration unit gave the best results.

Physical structure of activated sludge in aerobic stabilization
Water Research, 1971Abstract 1. (1) The physical structure of activated sludge flocs can be analysed and described to some extent by measuring the particle size and Thomas' α-value. 2. (2) During aerobic sludge stabilization both factors undergo changes which are paralleled by a reduction of organic matter within the flocs. 3.

Kinetic study of thermophilic aerobic stabilization of sludge
Biomass and Bioenergy, 1994Abstract Thermophilic aerobic digestion of raw sludge was studied and optimized at bench scale. Experimental studies were conducted using two bench scale systems. The first was an insulated closed stainless-steel vessel of 21 volume. The second digestion system consisted of three closed stainless-steel vessels of 51 volume each.

Mathematical model of aerobic stabilization of old landfills
Chemical Papers, 2012AbstractA short-term aerobic stabilization of digested waste in the final methane phase was studied. The effect of aeration rate on the reduction of leachate parameters and on the rate of CO2 production and O2 assimilation was investigated. Experimental simulation of aerobic landfill stabilization was carried out using lysimeters.

Microbiological Stabilization of Sludge by Aerobic Digestion and Storage
Journal of Environmental Engineering, 1993A study is conducted to evaluate the pathogen and indicator bacterial reductions in the sludges of two wastewater‐treatment plants. These plants are extended‐aeration and oxidation‐ditch‐type plants that have no aerobic or anaerobic digestion facilities following the secondary treatment except for sludge‐storage facilities.

Aerobic stabilization of tannery sludge
2005The wastewater coming from a tannery activity is often treated by biological treatment; the sludges produced by these processes are largely disposed off in landfill. The tannery sludge is currently a big ecological and environmental problem because of its high content of organic compounds and heavy metals, mainly Crome.
