RDVFs process slurry and discharge cake in a continuous process.They are used in a variety of industries including wastewater treatment,sludge dewatering,chemical manufacturing,the pharmaceutical industry,cosmetics,mineral mining and refining,and food processing.These filters are particularly suitable for slurry with variable cake thickness,moisture content,and stickiness.The operation involves slurry sitting in a tank with a partially submerged drum.As the drum rotates into slurry,a vacuum pulls the liquor through the filter media,trapping solid particles on its surface,forming a cake.The drum then goes through various zones including washing,drying,and discharge,with different discharge methods like scraper,belt,string,roll,and pre-coat discharge being used depending on the nature of the cake.2.Wikipedia Article-Rotary Vacuum-Drum Filter:The rotary vacuum drum filter is most suitable for continuous operation on large quantities of slurry,especially when the slurry contains a consid…
