ISC
Equipments
The following is a list of ISC equipment.
1- Centrifuging Equipment – Alpha Laval NX418 Three Phase Decanter
Centrifuge. This equipment is used to
separate the solids from one or two liquid phase. This is using
centrifugal forces that can be well beyond 3000 times greater than
gravity.
2- High Capacity Strainers - to strain the melted sludge.
3- Centrifuge control panels – operates the centrifuge and feed pumps.
Monitors the performance of the centrifuge machine.
Sludge Gathering Equipment
1 – Sludge melting tanks (two melting tank for each centrifuge
operating) – These rectangular tanks are normally 12 meters long, 2.5
meters wide, and 2.4 meters tall. They will have steam coils mounted
along the long sides of the tanks. The coils will be mounted
approximately 250 mm from the sides to allow a large open area down the
center of the tank. This opening will allow a small excavator to go
inside to scoop out sediments or debris when the tank has to be cleaned.
The tanks will have two agitators mounted on the top at each end to keep
the oil circulating around the coils.
The tanks will have a mesh barrier at the drain end to catch any large
debris from going into the transfer pumps. The mesh barrier will have 15
cm openings and span across the width of the tank near the drain end.
The coils will need to have a steam inlet at the top and a steam outlet
on the bottom to penetrate the tank walls. The steam connections will be
made outside the tank walls. A steam trap will be mounted at the steam
outlet outside the tank to enable the condensate to return to the
boiler.
2 – Transfer Pumps - The Gorman-Rupp transfer pumps suction is 50 mm,
single stage, and progressive cavity pumps. The pumps should be geared
to pump approximately 600 liters per minute.
3 – Transfer Pumps - The Gorman-Rupp transfer pumps suction is 50 mm,
single stage, progressive cavity pumps. The pumps should be geared to
pump approximately 600 liters per minute.
4 – 60 cubic meter Pre-Process Tanks (two tank for each operating
centrifuge) – The size of these tanks does not have to be exact. We
basically need at least 60 cubic meters of pre-process storage for every
centrifuge we have operating.
These tanks will need to have steam coils mounted in the bottom. We
normally make coils out of 2-inch pipe. Each tank will also have to have
an agitator mounted on the roof. Side mounted agitators can be used
also. It is best to insulate these tanks, but not critical.
1 – 60 cubic meters recovered oil tanks. Again, the size and shape does
not have to be exact. These tanks will be used to hold the recovered oil
before it is transported to KJO.
2 – 60 cubic meters extracted water tanks. Same as above, but will be
used to store the water extracted from the sludge before it is
transported to the disposal.
3 – 15 cubic meters diesel storage tanks. These tanks will be used for
storing diesel fuel for the boilers and electric generators.
Pipe, valves, fittings, steam traps and hoses – We normally use
three-inch pipe for the majority of the plumbing. We normally use 2-inch
pipe for all steam lines. We only use ball or gate valves. Butterfly
valves are not useable because of plugging. For estimation purposes,
there will be approximately 30 ball valves needed and approximately 16
check valves needed.
4 – Steam Boilers – 200 hp steam generating unit, complete with
accessories. Weathered sludge must be melted in order for it to be
pumped and processed. It is also used to heat the sludge to reach
optimal temperatures where the sludge can be easily separated.
We typically use diesel-fired boilers. These boilers will need to be
housed in a building or self contained in its own housing.
1 – 125 Kilowatt electric generators – These units will also need to be
self-contained. 460 Volts, 100 amps, three phase, power source for all
equipments needed on site.
2 – Compressor unit – 60 cfm to be used on various applications on site.
Other Support equipments
1 – 3 cubic meter water truck – used for delivering water
requirements on site.
2 – Diaphragm pump – used as transfer pump or for any other application.
