aerobic digestion

Stabilization can be achieved through microbial, anaerobic, or aerobic digestion.

In aerobic digestion, all of the compounds except the cresols, 2, 4, 5-trichlorophenol, and bis-2-ethylhexylphthalate were essentially eliminated.

The most common treatment options include anaerobic digestion, aerobic digestion, and composting.

In both cases, the biomass must be exposed to both wastewater and air for the aerobic digestion to occur.

Aerobic digestion and aerobic composting are same kind or related kind of processing options.

Studies have demonstrated that GHG emissions are reduced using aerobic digestion systems.

Key words: aerobic digestion, biological nutrient removal, denitrification, methanol, sludge dewaterability.

Aerobic digestion can also be achieved by using diffuser systems or jet aerators to oxidize the sludge.

Type 2 MSD's are usually reliant upon biological or aerobic digestion of bacteria present.

Autothermal thermophilic aerobic digestion can produce a biologically stable product while reducing both sludge mass and volume.

Mesophilic aerobic digestion had gradual and continued effects that deteriorated dewaterability of all types of sludge.

The waste water is subsequently pumped to a biological treatment tank which converts the waste material with an anoxic and aerobic digestion process.

In turn the methane and oxygen energize the aerobic digestion of the end-products of the anaerobic breakdown.

Pilot-scale research into the characterization and enhancement of the aerobic digestion of waste-activated sludges was performed.

The removal of selected toxic compounds during anaerobic and aerobic digestion of municipal sludge was investigated at pilot scale.

• Waste-activated sludge is usually stabilized on site through aerobic digestion and may be further thickened or dewatered prior to ultimate disposal.

Aerobic digestion is a bacterial process occurring in the presence of oxygen resembling a continuation of the activated sludge process.

Key words: aerobic digestion, anoxic, intermittent aeration, lime, pilot-scale, Redox potential, sludge, solids reduction.

Key words: biological nutrient removal, carbon source, digested sludge supernatant, thermophilic aerobic digestion, volatile fatty acids.

However, the operating costs are characteristically much greater for aerobic digestion because of energy used by the blowers, pumps and motors needed to add oxygen to the process.

The City of Winnipeg does organic material processing and energy recovery by using aerobic digestion - one of the methods for managing organic waste.

Key words: activated sludge, aerobic digestion, hydrated lime, mixed-liquor pH control, nitrification, process enhancement, pilot-scale, sodium bicarbonate.

PFRPs include pasteurization, heat drying, thermophilic composting (aerobic digestion, most common method), and beta or gamma ray irradiation.

Work will also look at how these substances pass through the aerobic digestion process, complementing a parallel study of the optimization of anaerobic sludge digestion processes.
