Highly Efficient Inclined Screw Thickener
Product Description
Product Description
The BOEEP Inclined Screw Thickener stands out from traditional volute screw press dewatering machines with its low operational and maintenance costs, superior dewatering performance, odor control, and quiet operation. Designed for sludge with low concentrations (2500mg/L to 20000mg/L) from secondary sedimentation tanks, this device ensures rapid and continuous thickening. It efficiently adjusts sludge concentration to a stable range of 90%-96% without the need for a concentrated tank, offering a compact footprint and cost-effective solution. Additionally, the Inclined Screw Thickener minimizes odor and phosphorus release, simplifies subsequent treatment, and enhances the capacity of sludge dewatering and dehydration equipment.
Main Structure & Working Principle
BOEEP inclined screw sludge thickener is composed of screw body, driving device, filtrate receiver, mixing system and frame. There are 3 parts which constitutes the main body of volute screw press thickener. They are fixed ring, moveable ring and the screw shaft which runs through the main body.
BOEEP inclined screw sludge thickener mainly consists of concentrating body, driving device, filtered water tank, mixing system and frame, etc. During operating, the sludge is pumped into the mixing tank by sludge pump, meanwhile, dosing pump feeds the mixing tank with prepared polymer quantificationlly. The sludge is mixed completely with the polymer by the stirring of motor in the mixing system, then flocs will be produced. When the liquid reach the level of liquid level sensor, the screw body will get into operation, in which the sludge is being pressed. The thickened sludge will be discharged at the outlet gradually and the filtered water will come out between the fixed ring and moving ring at the same time.
All in all, inclined screw sludge thickener adopts the principle of screw extruding to thicken the sludge through the high pressure generated by the screw distance changes and small gap between the mobile ring & fixed ring.
Application
1-Solid and liquid separation in the municipla & industrial wastewater treatment system.
2-Sludge dewatering in the municipal & industrial wastewater treatment system.
3-Instead of condensed tank, work as the pre-treat device of the sludge dewatering system.
4-It is the pre-treat device of sludge deep dewatering, also as the auxiliary equipment of high pressure plate and frame filter press, membrane filter presser.
5-Other wastewater treatment applications in the municipal & industrial wastewater treatment system.
