Lab scale candle filter testing at our customers’ facilities represents a win-win situation for both our customers and DrM alike. Lab scale filter testing serves multiple functions. It permits us to show our customers that we can help them achieve their filtration as well as valuable liquid and solid recovery goals. Application process and cost benefits can be projected once repeatable test results have been achieved. It also permits us to prove that scalability is achievable and allows for scientific and reliable sizing of DrM full-scale filtration systems. The available filter area range of these units is from 0.012 m2 to 7 m2 in surface area. We offer both manual and fully automatic units in a wide array of materials of construction. Most are available from our inventory on short notice.
The TSD Lab Filter offers the same features as our full-scale industrial FUNDABAC® candle Filter, but on a bench scale. The unique features of the FUNDABAC® filter element having an outside diameter (OD) of 82 mm at full scale have been scaled down to 30 mm OD. The resulting filter area is 0.012 m2 (0.13 ft2). The same types of filter media which are used in our industrial scales filter are available for us in the TSD. The filters offer the same functions as our industrial scale units such as filtration, cake washing under pressure and cake discharge as slurry via backwash. For dry discharge, the cake is dried by gas prior to blow-back. Using the TSD, our field service technician can demonstrate process concepts to his counterparts who in many cases are chemical engineers and project managers. Our field service representative will demonstrate the optimum manner of cake discharge. Filterability of the liquid can be determined at different cake thicknesses and pressures. Additionally, optimal levels of filter aid precoat and bodyfeed can be determined, if it is determined that these materials are beneficial. Our TSD Lab Filters have built in heating/cooling jackets to further enhance testing flexibility.
Our laboratory and pilot scale filter systems are not only available for testing purposes. New and used units are also available for purchase for low-volume production scenarios or use at your own testing facility.
