It is also used to improve extraction of liquid products or dissolved materials from the filter cake. In these cases, the filter would be operated intermittently as needed to filter a batch of feed slurry.Ĭake washing is used when a given cake purity is required. Yes, although the filter operates as a continuous separation device, it can be used in batch processes. Further testing using a test leaf can be done to simulate the operation of the RDVF under specific operating conditions.

Is there an easy test to tell if an RDVF is right for an application?Ī simple Buchner funnel test will generally determine if the use of an RDVF is feasible. In wastewater applications it can be used to dewater a variety of sludges or to clarify wastewater. It can be used in process applications where the solid is the product or where the liquid is the product (and sometimes when both phases are the product). It is used where a continuous separation of a solid from a liquid stream is desired. The rotary drum vacuum filter is a very versatile liquid/solid separation device. All of these should be considered when selecting a filter. 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. There are many factors affecting the operation of a filtration process. Do you have any standard specifications?.Do you need any instrumentation or controls?.What materials of construction are acceptable? What are not?.What have you tried before? Why did/didn’t it work?.What is most important: cake solids, filtrate clarity, capital or operating cost, etc.?.What is immediately upstream and downstream of the filter?.Perform lab and/or pilot scale testing if necessary.Contact us to assist in making a preliminary selection.Complete the K-S Applications Questionnaire.Establish process inlet and outlet conditions as accurately as possible.If you can relate to these objectives, then follow these steps: Our equipment requires minimal operator attention as well as low maintenance time and expense, and is designed and built for long equipment life. Cake washing for cake purity or liquid product extraction.Continuous separation of solid and liquid.If your process involves any of the following, then the Komline-Sanderson Rotary Drum Vacuum Filter may fit your needs. How do I know if an RDVF is right for my process?
