DEWATERING SCREW PRESS Working PrinciplesThe conditioned sludge
flows into the filter zones from the flocculation tank and is
pushed forward to the discharging end. With the gaps between the
thread of the shaft getting even narrower the pressure on the
sludge is getting higher and higher. Then the water is separated
from the sludge and flows out from the gaps between the moving
rings and fixed rings. The movement of the moving rings will clean
the gaps between moving and fixed rings and prevent the machine
from blockage.The filtered sludge cakes will be pushed forward by
the finally discharged from the end.DEWATERING SCREW PRESS
DescriptionJuntai Multi-Disc Sludge Dewatering Screw Press belongs
to the screw press, it's clog-free and can reduce the sedimentation
tank and sludge thickening tank, saving the cost of sewage plant
construction.HLDS uses screws and moving rings to clean itself as a
clog-free structure, and controlled by the PLC automatically, it's
a new technology that can replace the traditional filter press like
belt press and frame press, the screw speed is very low, and so it
cost low power and water consumption in contrast to the centrifuge,
it is a cutting edge sludge dewatering machine.Applications:The
Sludge Dewatering Screw Press can be widely used for various
wastewater treatment systems such as municipal, petrochemical,
chemical fiber,paper making, pharmaceutical, leather and other
industrial water treatment system.Also it can be used for Dairy
Farm Manure Treatment, Palm Oil Sludge, Septic Sludge, etc. The
practical operation shows that Dewatering Screw Press can bring
considerable economic and social benefits for users.Advantages:1.
Enclosed to minimize odors and noise Very low wash water usage (1/8
compared with belt press)2. Very low power consumption (1/20
compared with a centrifuge) 3. High cake solids4. Minimal operator
requirement 5. Easy to operate and maintain 6. Auto Start-up, Run,
and Shutdown 7. Touchscreen operation optional 8. Sludge Flow and
Cake Monitoring Systems9. Available with many other options like
Dairy, Palm Oil, etc.Technology AdvantagesSludge Concentration
2000mg/L-50000mh/LConfiguration exclusive spiral plate for
pre-concentration and better for treating low-concentration
sludge.1. Replacing gravity-type dehydrator to realize efficient
concentration of sludge.2. Flocculation and concentration operating
together make dewatering easy.3. Optimize the concentration of
slurry for dewatering with a solenoid control valve. Rings
substitute filter cloth, self-cleaning, no clogging, easy
treatmentThe traditional dewatering equipment easily got blocked
while the dewatering screw press allows continuous operation with
no clogging due to the moving of the fixed rings and moving rings
cleaning itself. Therefore, it's especially good at oily sludge
with excellent performance. Moreover, it doesn't need additional
water for high-pressure cleaning so no small or secondary pollution
will be produced.The low-speed operation, low noise, low energy
consumption, only 1/8 of the belt type, 1/20 of the
centrifugeSemi-Automatic PET Bottle Blowing Machine Bottle Making
Machine Bottle Moulding Machine PET Bottle Making Machine is
suitable for producing PET plastic containers and bottles in all
shapes.Comparison ChartReduce the cost of infrastructure
investment, improved the result of treatment1. The dewatering screw
press can directly treat the sludge from the aeration tank and the
sedimentation tank so that the sludge thickening tank is not needed
anymore. Therefore, the construction cost can be greatly reduced
and well avoided the phosphorus releasing problem.2. Saving
the cost of sludge thickening tank and other equipment
investment.3. Occupy smaller areas, and reduce construction
investment for dewatering.Fully automatic control, easy operation,
and maintenanceThe dewatering screw press has no easy-blocking
components like filter cloth or filtration pore inside.Its
operation is safe and easy. It also can be set to operate
automatically via the elec-control cabinet.Integral
