sewage sludge, industrial sludge or dredging sludge
Common sludges (excluding dredging spoils
Sludge to be treated is combined with recycled anaerobic digester sludge to form a blended sludge.
At a stage after the separation of the primary sludge and the excess sludge from the sewage, a nitrite salt is added to the primary sludge and/or the excess sludge.
Leaded gasoline sludges and leaded anti-knock compound sludges
Leaded gasoline sludges and leaded anti-knock compound sludges
metal hydroxide sludges and other sludges from metal insolubilisation treatment
The sludges contained in the liquids flown from these biological disposal steps are subjected to solid-liquid separation in a settling pond (41) and then the obtained sludge thus formed is supplied to a sludge disposal tank (51).
ink sludges free of halogenated solvents
Non-sewage) sludges are allowed only if they meet the following criteria
sludge treatment section capable of producing reusable material
Sludge discharged from the sludge pool enters the sludge concentration tank (12) to undergo concentration treatment.
the names and addresses of the recipients of the sludge and the place where the sludge is to be used
A sludge treatment system comprises a sludge pool (11) for receiving sludge, and a dehydration treatment system for performing dehydration treatment on the sludge.
The present invention also provides a sludge heating method and a sludge hydrolysis apparatus using same.
The quantity of water pumped to the slurry vessel (18) is controlled so that the resulting slurry can be pumped from the slurry vessel (18) via the slurry pump (50).
SVI
This invention relates to processes for modifying the flow characteristics of slurries, particularly mineral slurries such as red mud from the Bayer process, using water-soluble polymeric emulsions to increase the slurries' angle of repose.
soil (including excavated soil from contaminated sites), stones and dredging spoil
soil and dredging spoil
The mobile pumping station (10) further comprises a relatively large slurry pump (50) used to pump slurry from the base of the slurry vessel (18).
Sludge combined heat and power installation
A process (1) for aerobic treatment of sludge and the like, which consists of a first step of sludge thickening and a second step of sludge dehydration.
The sludge input capacity of the hopper (300) is adjustable in accordance with input sludge conditions.
A method of treating sewage sludge comprises incubating raw sludge at a temperature in the mesophilic range to reduce the pathogen content of the sludge.
Of which: sewage sludge gas
Simulation test Aerobic sewage treatment, Activated sludge units (OECD 303A
The invention relates to a device for dehydrating sludge, such as occurs in sewage treatment plants in the form of dilute sludge.
x-ray diffraction pattern of a mucklike deposit
The system allows removal of the water from the tailing followed by RF energy absorption by the tailing prior to substantial heat transfer to the surrounding mineral portion of the tailing.
