Rotary Drum Sludge Enrichment Dehydrator
The working principle of the rotary drum sludge thickener is elegantly simple; it involves feeding the sludge into the dynamic reactor through a sludge and dosing pump, directing it to the rotary drum inside the thickener. The rotary drum, equipped with a compound filter cloth, rotates at a steady speed of around 10 RPM. As water passes through the filter cloth, the flocculated sludge is retained, ensuring optimal thickening. To maintain filter cloth integrity, cleaning nozzles consistently refresh it with soft impact, preserving the delicate floccules. The resulting sludge concentration post-thickening is influenced by the solid content of the feed, flocculation dosing quantity, drum rotation speed, and its dip angle.
