What are the common river silt treatment equipment?

River sludge cleaning equipment, the plate and frame filter press is a device for sludge treatment in the sewage treatment system. Its function is to filter the sludge after sewage treatment to form a large filter cake for removal.

As a mature dehydration equipment, the filter press has been widely used in the field of environmental protection and has become an important equipment for sewage and sludge treatment. The mechanical dewatering of sludge is mainly to remove the capillary water between the sludge particles. The moisture content of the sludge after ordinary mechanical dewatering is usually 65%-80%. The mechanical dewatering equipment in the form of a mud cake mainly includes a belt filter press, a plate and frame filter press and a horizontal spiral sedimentation centrifuge. Nowadays, box-type filter presses, vertical hydraulic filter presses, diaphragm presses and high-pressure plate and frame presses are commonly used.

The plate and frame filter press discharges the water in the sludge through the filter cloth through the squeeze of the filter plate, so as to achieve the purpose of dehydration. It is also called slurry dehydration, that is, a certain number of filter plates are closely arranged in a row under the action of strong mechanical force. A filter chamber is formed between the surface of the filter plate and the surface of the filter plate. The filter material enters the filter chamber under strong positive pressure and enters the filter. The solid part of the filter material in the chamber is intercepted by the filter medium (such as filter cloth) to form a filter cake, and the liquid part is discharged from the filter chamber through the filter medium to achieve the purpose of solid-liquid separation

Advantages of plate and frame filter press

1. Automatic control, continuous operation;

2. The filter plate has high strength and can withstand high filtration pressure

3. The dehydration efficiency is high, and the mud cake can't get the water out of the hand;

4. Fast filtration speed and long service life

5. Low noise and less chemicals;

Equipment performance

The mud has a low viscosity and is easy to filter. A filtration cycle time is: 60 minutes;

The mud has a high viscosity and is not easy to filter. The time of a filtration cycle is: 90 minutes;

The use effect of the plate and frame filter press:
