Filter Press Filtration

long working life is achieved due to most modern production techniques as well as to an excellent chemical resistance of the used thermoplastic materials even under high temperature. High Product Quality A quick drainage and an excellent washing of the cake result in a high product quality. The hydrophobic surface prevents resp. delays plugging of drainage channels. Fast Filtration The special design of chamber plates leads to shorter filtration cycles and an increase in capacity. Slight Cloth Strain The smooth plastic surface reduces friction between filter cloth and plate surface. Excellent Sealing The accurately machined surfaces of the filter plates in accordance to DIN 7129 together with the filter cloth ensures a very good sealing of the filter plate package. A sealing free of leakages is possible by the CGR-design Good Heat Insulation Compared to filter plates made from metal there is almost no loss in energy even under high working temperature. Easy Cleaning The inert hydrophobic surface of PP rejects dirt, absorbs less than 0,1% water and makes a quick product conversion possible. Low Weight The low weight makes handling easy and shortens filtration cycles. Chamber Plates in various sizes CONSTRUCTION The ICM process developed by JVK allows the production of homogeneous filter elements without insert parts in any required thickness. This procedure is representing the leading technology for the production of parts with low tension. Taking into consideration possible high filtration pressures the transitions filter area to sealing rim and support bosses were designed by FEM (Finite Element Methode) to achieve the lowest possible tension. The dia. of the pips as well as the corresponding distances within filter area were optimized for a low cloth load. The standard designs of the chamber filter plates can be used up to 15 bar filtration pressure and 90° C temperature. In case of very extreme working conditions, as high pressure over 15 bar and high temperature over 90° C , JVK is able to offer very special designs. FUNCTION The JVK chamber filter plates are used for pressure filtration only. In general steps are as follows: Filtration / feeding of filter press Washing / removal of liquids or salts from the cake Blowing / removal of cake from feed port and / or drying of cake.

Membrane Chamber Plates

ADVANTAGES OF THE MEMBRANE CHAMBER PLATE Because of the high elastic membranes, pure membrane packages are not necessary in most fields of application. The combination of JVK membrane chamber plate together with combination chamber plate is saving investment and operating costs. JVK membrane chamber plates are used for the solid-liquid-separation in all industrial processes. The most advantages are obtained in that cases where squeezing effects due to high elastic membranes are becoming effective on filter cake. The reliable JVK membrane chamber plate system with detachable membranes is a very good investment with short capital return time for each company using filtration: Short filtration cycles Short washing cycles Low residual moisture Exchangeable membranes No direct load on membrane due to press closing force High elasticity of membrane No problems during membrane move- ment even in the empty chamber Time-independant membrane movement Sealing of filter plate system Large cross-sectional area of filtrate outlet Many fields of application Safety factor of the membrane system

Plates and Frames

Filter plates and frames are used in our days only in very special cases. It is possible to use overhang filter cloths or even flexible filter media from cotton or paper. Compared to chamber plates the field of application is limited with regard to filtration pressure and filtration temperature. Available in various designs and sizes for filter cloth bags or integrated filter cloth with grooved or pipped filter area More detailed information is available on demand
