Enhanced storage stability of aerobic granules seeded with pellets

Bioresource Technology, 2010
The 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.

Methods for measuring the degree of stability of aerobic stabilized sludges

Water Research, 1977
Abstract This study was conducted to find one or several parameters that can be used as a measure of the degree of stability of wastewater sludges and to define in terms of the measured parameters what is meant by a fully stabilized sludge. Based on the data from this study, the following requirements regarding odour should be met before an ...

N6-methyladenosine reader YTHDF3 contributes to the aerobic glycolysis of osteosarcoma through stabilizing PGK1 stability

Journal of Cancer Research and Clinical Oncology, 2022
N6-methyladenosine (m6A) modification is a pivotal transcript chemical modification of eukaryotics, which has been identified to play critical roles on tumor metabolic reprogramming. However, the functions of m6A-reading protein YTH N6-methyladenosine RNA-binding protein 3 (YTHDF3) in osteosarcoma is still unclear.

Kinetic study of thermophilic aerobic stabilization of sludge

Biomass and Bioenergy, 1994
Abstract 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.

Laboratory studies of aerobic stabilization of swine waste

Journal of Agricultural Engineering Research, 1966
Pig 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.

Mathematical model of aerobic stabilization of old landfills

Chemical Papers, 2012
AbstractA 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.

Physical structure of activated sludge in aerobic stabilization

Water Research, 1971
Abstract 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.

Studies on the aerobic stability of commercial silages

Journal of the Science of Food and Agriculture, 1979
AbstractEighteen commercial silages from ten different farms located in south‐east Scotland were exposed to air in polystyrene containers over a 9‐day period. The silages were subjected to detailed biochemical and microbiological analyses prior to aeration.

The Microflora Involved in Aerobic-Thermophilic Sludge Stabilization

Systematic and Applied Microbiology, 1989
Summary The microflora adapted to the habitat of aerobic-thermophilically treated sludge was investigated in a laboratory-scale fermenter as well as in plants working in practice. As demonstrated by the immunofluorescence technique, the dominant microflora of the laboratory model plant working under steady-state conditions largely corresponds to that

Stability Measurement of Biosolids Compost by Aerobic Respirometry

Compost Science & Utilization, 1995
Oxygen uptake of biosolids compost was measured during both laboratory and full-scale studies. Aerobic respirometry of solid samples of compost provided a precise measure of microbial activity. There was a noticeable decreasing trend in oxygen consumption over 25 days of composting, thereby indicating increasing stability.
