Treatment of N, P of auto-thermal thermophillic aerobic digestion
fluid with struvite crystallization.
Waste less than 50mm will be sent to Anaerobic & Aerobic Digestion
and Composting plant through feeding conveyor system and will be fed into the digesters automatically based on the daily operation requirement.
The proposal is for a power station and aerobic digestion
plant to be sited on an old quarry and residents have spent the last two years mounting a campaign against it.
pathogens or known sludge bulking species) to be detected early and monitored throughout the aerobic digestion
Newton Aycliffe company John Wade is building an aerobic digestion
plant at a cost of almost pounds 4m for its main clients Darlington Council.
The Tri-Mer system serves as a practical alternative to thermal oxidizers, in-bed biofiltration and aerobic digestion
for the control of VOC emissions from a wide range of sources.
The three councils in the South of Tyne and Wear Partnership are considering nine options, which include: to continue as currently; anaerobic digestion of all waste; mechanical biological treatment (refuse-derived fuel); mechanical biological treatment (landfill); autoclaving (re-fuse-derived fuel); energy from waste (incinerator); advanced thermal treatment (incinerator); aerobic digestion
and energy from waste (combined heat and power, incinerator).
From the original nine available options the partnership has whittled the options down to a preferred two: aerobic digestion
and energy from waste - combined heat and power.
He gives methods of solid separation, recycling technologies such as stabilization, composting, anaerobic treatment, themophilic aerobic digestion
, duckweed and fish ponds, struvite and direct urine reuse, nutrient removal through kinetic and other processes, post treatment through advanced processes, and integrated systems such as manure-based biogas plants.
The Liverpool (LI) biosolids were also from anaerobic digestion but with secondary digestion, while the Quakers Hill (QH) biosolids were from tertiary aerobic digestion
composting, anaerobic lagoons, aerobic digestion
, and direct incineration);
Note that anaerobic digestion (in the absence of oxygen) is different from aerobic digestion
(in the presence of oxygen) - and that both can be seen in the formation of compost.
