Belt Sludge Dewatering Filter Press , Mechanical Filter Press

Quick Detail:

.
BCY Wastewater Solutions offers a range of Belt Presses from 500 mm wide to 3000 mm. The Belt Presses feature rotary drum thickeners or gravity deck thickening. large throughput, low moisture content, low chemical consumption, low operating cost,  stable performance, easy to operation, cleaning and maintenance

Description:

The BCP series of belt presses utilizes a combination of chemical conditioning, gravity drainage and mechanical pressure in a continuous feed system to dewater sludge. The sludge is squeezed between tensioned serpentine belts and a series of decreasing diameter rollers to remove moisture and create a dewatered sludge cake.

BCP belt presses are manufactured with a belt width ranging from 0.5 to 3 m and with varying levels of automation. Belt presses can be supplied as a free standing unit or as a part of a complete sludge dewatering package, customized to suite any waste treatment needs
Features include:

• Stainless steel or mild steel construction
• Continuous and fully automatic operation
• Hydraulic or pneumatic drive and positioning systems available
• Open design for ease of maintenance
• High dewatering performance due to efficient roller arrangement
• High quality bearings with airproof bearing seats
• Various levels of automation available
• BCP belt presses can also be supplied with a range of additional equipment, including:
• pH control systems
• Chemical dosing systems
• Chemical mixing systems
• Flocculant injection systems
• Sludge conveying systems

Applications:

1.         City sewage treatment sludge
2.         Water treatment sludge
3.         Household waste water treatment sludge
4.         Excrement treatment sludge
5.         Butchery waste water treatment sludge
6.         Paper/pulp sludge
7.         Processed marine sludge
8.         Chemical sludge
9.         Mountain waste water sludge
10.        Food processing sludge

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.
