Product Details
Multi disc screw press dewatering for waste water treatment in
dairy factory SS304
Direct dewatering the oxidation ditch
The Sludge Dewatering Press is an enclosed high performance sludge
dewatering system. It utilizes a central screw auger and a slowly
oscillating multi-disk filter to gradually increase pressure on
flocculated sludge to produce an exceptionally dry sludge cake.
With electrical, water and polymer usage, and high capture rates
the system is very cost effective.
The Sludge Dewatering Press can be provided with all equipment
required for dewatering included and factory mounted, piped and
wired on a single stainless steel skid. This equipment includes the
sludge pump, wash water pump, polymer dosing system and control
panel. The system features fully automated one pushbutton startup
and shutdown. Once started up the system can run unattended and can
be set to shutdown automatically with no operator intervention.
Application
- Sewage and waste water treatment plants of municipal water
- Waste water treatment plant in agricultrual & fishery community
- Industrial waste water treatment plants
- Effluent treatment plant in food & beverage production plants
- Dairy farming / meat processing plants
- Chemicals manufacturing plants
- Machinery manufacturing plants
- Laundry wastewater treatment
- Paper & pulp, building material manufacturing, oilfield
associated waste water containing crude oil mining.
Technical introduction
The volute is structured with a filter element that consists of two
type rings: a fixed ring and a moving ring; and a screw that
thrusts the filter element and transfers and pressurizes the
sludge. The gaps between the rings and the screw pitch are designed
to gradually get narrower towards the direction of sludge cake
outlet and inner pressure of the filter element increases due to
the volume compression effect, which thicknens and dewaters the
sludge.
Features:
- The dewatering body is formed by a screw axis with fixing and
moving plates overlapping, as the inner diameter of screw axis is
larger than the moving plate, the moving plate do the circular
motion with the screw axis to prevent clogging, to ensure the
continuous operation
- Municipal wastewater, papermaking wastewater, chemical waste water,
food and beverage processing waste water, industrial wastewater,
papermaking wastewater, pharmaceutical wastewater, oil processing
and mining wastewater, etc.
- Comparing with the traditional belt, plate& frame and
centrifugal machine,volute sludge dewatering machine adopts
integrated design of dehydration ontology, flocculation mixing tank
and electric control device, convenient installation , small area
cover, strong compatibility with ancillary equipment, greatly
reduce design and the construction cost, at the same time, no need
to undertake civil construction as its exquisite design.
- Can realise 24 hours automatic unmanned operation by PLC remote
control , reduce the operating personnel employment and maintenance
costs. At the same time, due to the exquisite design, easy
operation, it is easy to learn as no special knowledge and skilled
technical complex requirements.
- Main body can self-cleaning due to the special structure, threr is
no need to use a lot of water for cleaning to prevent clogging.
Compared with the same capacity of dewatering machine, screw rinse
water consumption is only 1% of belt . The rotation speed of screw
shaft is 2-5 turn/min , low power consumption. Power consumption is
only 5% of the centrifuge, at the same time, no noise during
operation as slow rotation speed and intermittent flush.
