Carbon Steel Waste Water Filter Press For Municipal Waste Dewatering

Applications:

Sludge dewatering for industries of ceramic, metallurgy, coal wash, textil&dyeing, city sewage, papermill, electroplate, petrochemical, leather distillery, food processing, chemical, medicine, etc.

Type, size and specifications:

According to the specific sludge capacity requirement, the width of macine can be chosen from 1000mm-3000mm.(the choice of thickening belt and filter belt would vary according to different types of sludge). Stainless steel of belt filter press is also available. it's our pleasure to offer the most suitable and most economic effective proposal for you according to your project!

Working principle:

After mixing with the prepared flocculation in the dynamic and static mixer, the small particles solids in the concentrated sludge would form bigger size of flocculated sludge and the free water is separated. Flocculated sludge is conveyed to the belt then it further goes to the gravity dewatering area. Under the gravity, free water would fall on the tray, and the rest sludge would be nipped between two belts. Then it would further goes to the wedge zone for pre-filtration, and then to low pressure zone and high pressure zone through the decreasing diameter rolls. Under the extrusion and shearing force, the solid and liquid is separated. Finally filter cake with expected low moisture content is discharged.

Dewatering flow sheet:

For different industrial sludges, different type of flocculants is required. Normally the feeding consumption is about 0.05%-0.1%. According to different throughput, the roller quantity, extrusion allocation, belt tension, structure and speed is also different in order to achieve an efficient and satisfied dewatering effect. Therefore, we would make unique design to meet the requirement of every customer.
