Rotary Drum Vacuum Filter K-S Rotary Drum Vacuum Filters Komline-Sanderson continuous rotary drum vacuum filters for the separation of liquids from solids offer great flexibility in meeting the needs of many industries. Our experience ranges from simple separations to complex multi-stage applications involving filtration, clarification, extraction, cake washing, and drying. The rotary drum vacuum filter offers: Continuous Operation Application Versatility Wide Range of Sizes For horizontal vacuum filtration, please see our Horizontal Vacuum Filter For information on our filtration media please visit Fabrics 12 Applications Benefits Design System FAQs The Komline-Sanderson Rotary Drum Vacuum Filter is applied to process and waste slurries for filtering, clarifying, cake washing and extraction, and dewatering. Industries served by K-S include inorganic and organic chemicals, pharmaceuticals and biotech, plastics, food products, minerals, electric power and other utilities. Specific process applications are referenced in the Design Section. How does it work? The process of the RDVF is continuous. Each revolution of the drum consists of cake formation, cake washing (if needed), dewatering or drying, and cake discharge. As the drum rotates, it is partially submerged in the feed slurry. Vacuum draws liquid through the filter medium (cloth) on the drum surface which retains the solids. Vacuum is applied using a liquid ring vacuum pump or other means. The vacuum pulls air (or gas) through the cake and continues to remove moisture as the drum rotates. Finally, the cake is discharged from the drum to a conveyor or chute to the next process step. The filtrate and air pulled through the medium flow through internal filtrate pipes and pass though the rotary valve and into the filtrate receiver. The liquid stream is separated from the vapor stream in the receiver. Liquid filtrate is then pumped to the next step in the process. If required, the cake can be washed to remove impurities or to extract more product. Additional drying of the cake follows washing. How do I know if an RDVF is right for my process? If your process involves any of the following, then the Komline-Sanderson Rotary Drum Vacuum Filter may fit your needs. Continuous separation of solid and liquid Solid or Liquid Product recovery Clarification of liquid product Cake washing for cake purity or liquid product extraction Clarification of a wastewater stream Our equipment requires minimal operator attention as well as low maintenance time and expense, and is designed and built for long equipment life. If you can relate to these objectives, then follow these steps: Establish process inlet and outlet conditions as accurately as possible Complete the K-S Applications Questionnaire Contact us to assist in making a preliminary selection Perform lab and/or pilot scale testing if necessary Make final selection Other important considerations: What is immediately upstream and downstream of the filter? What is most important: cake solids, filtrate clarity, capital or operating cost, etc.? What have you tried before? Why did/didn’t it work? What materials of construction are acceptable? What are not? Do you need auxiliary equipment? Do you need any instrumentation or controls? Do you have any standard specifications? There are many factors affecting the operation of a filtration process. Among these are the need for chemical pretreatment; the need for precoat or filter aid; power, water, air, or other utilities; operator attention; cleaning requirements; and maintenance needs. All of these should be considered when selecting a filter.
