Multi-Disk Screw Press ( Hereinafter referred as MDS ) 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. MDS using screw and the moving rings to clean itself as 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.

Small Sludge 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. MDS using screw and the moving rings to clean itself as 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.

LIFENG is professional manufacturer of sludge dewatering containerized plants. For each case, we provide a solution which is going to use portable system or stationary. You will get reliable and practical plants and only need plug and play at site. All procedure of machines is sort inside one container. For best performance we use the MDS/TRP with sludge dewatering machine completed with automatic dosing device, agitator, tanks, pumps included cabling,

The function of chemical dosing device is to dissolve powder flocculants or dilute liquid flocculants. Volume = DS Reference Treatment Capacity per hour of configured dewatering machine x Flocculants addition rate x Dilution ratio x Retention time.

Model Selection : Dosing pumps are used to deliver polymeric coagulant or inorganic flocculants to the flocculating tank. Due to the high viscosity of polymer coagulants, we should choose high viscosity resistance dosing pumps. Flow = DS Capacity per hour of configured dewatering machine ÷ Flocculants addition rate ÷ Dilution ratio.

TRP solid liquid separator adopt a unique separation technology. It’s brand new dewatering technology, which enables self-cleaning automatically for the filter gaps during sludge thickening and dewatering. Meanwhile this machine has stable and constant capacity without depending on high pressure backwash water to prevent clog. This self-cleaning system enables TRP sludge dewatering press to be a good machine for oily and grease sludge.

Model Selection: The selected pump should continuously transfer quantificational sludge from sludge tank to the flocculation tank as per actual running request. Flow = DS Reference Treatment Capacity per hour of configured dewatering machine/ sludge concentration.

Model Selection: Sludge conveyor unit is used to convey the discharged sludge cake. The height from the bottom of sludge cake outlet to the ground must be put into consideration during selection, and the width of inlet of sludge conveyor should be slightly wider than the carrier plate. Sludge cake throughput = DS Capacity per hour of configured dewatering machine / solid content of sludge cake.

Due to the special requirements of the fan installation site, different types of fans with different air outlet forms are required. Therefore, centrifugal fans are divided into "right" rotation according to the different rotation directions during fan manufacturing; Left rotation; Two forms. The basic method to determine the rotation direction of a fan is to stand at one end of the fan drive shaft (or the end of the motor) and face it in front. If the fan impeller rotates clockwise, it is called "right" rotation. Turning counterclockwise is called `left` rotation.
