Diaphragm Filter Plate Technology
The direct demands of industry`s process and wastewater treatment applications over the last twenty years have accelerated the development of variable volume membrane (diaphragm) filter plate technology. Diaphragm Filter Plates An intensive analysis into the present-day requirements for a diaphragm filter plate in conjunction with the experience of competent users in the field preceded the development of the Klinkau diaphragm filter plate. The three prominent requirements of diaphragm filter plate technology is to Increase cake solids over conventional dewatering devices Reduce the filtration cycle time to increase production yield Improve cake washing capabilities to increase product yield The Klinkau diaphragm filter plate product line was developed to meet and exceed these requirements as well as improve other demands of the liquid / solid filtration marketplace. The final volume of the diaphragm filter plate chamber after the squeeze cycle will vary depending on many factors such as slurry filtration characteristics, slurry feed time , slurry feed pressure, filter cake compressibility, squeeze pressure, and squeeze time, etc. Advantages of Diaphragm Filter Plate Technology Solid / liquid filtration can be accomplished by various techniques, such as centrifuges, rotary drum vacuum filters, belt filter presses, recessed chamber filter presses and also diaphragm filter presses. Quite often, the final selection of a filtration method is determined by the requirement for the degree of dryness of the filter cake and the quality of the filter cake composition. Some years ago, the results achieved on a standard recessed chamber filter press were quite acceptable until the Diaphragm filtration technology created better cake quality with higher solids content. The two techniques - conventional recessed chamber filtration and diaphragm filtration differ in one major important point: The final dewatered cake is a result of mechanical squeezing by the diaphragm. In a conventional recessed chamber filter press, the filter cake is formed in layers until the chamber is completely filled with solids. As the filter cake is being formed, its permeability and flow rate decrease as the solids increase in the chamber. Intense compressible products reduce the cake permeability causing long filtration cycles and increased operating costs. Reduced Cycle Times The significant advantage of the diaphragm filter plate technique is that the pressure filtration phase is conducted in only the efficient stage of the filtration cycle. The unproductive phase of the pressure filtration, where the flow rates are already greatly reduced, is replaced by squeezing with the diaphragm. In most conventional recessed chamber filtration cycles, the majority of the cake is formed in the first half of the cycle time. The diaphragm plate technique allows the flexibility to vary the final cake volume based upon process conditions. Increased Cake Dry Solids During the diaphragm squeezing cycle, the porosity of the filter cake decreases notably, so that additional dewatering occurs. With conventional pressure filtration, the cake next to the filter cloth is drier than in the center due to uneven distribution of pressures in the filter cake. The diaphragm squeeze technique will provide an even spread of pressure so that a homogeneous porosity is created within the cake. The average grade of dewatering is profoundly higher with diaphragm filtration technology compared to recessed chamber filter plate filtration. Diaphragm filter plate technology can produce final cake solids 30% to 100% greater than conventional recessed chamber filter plate filter presses. Due to shorter filtration cycle times and increased final cake solids, the filtration process efficiency (yield) can be improved up to 100%. Improved Cake Wash Capability Cake wash after filtration is a major requirement in many filtration applications. The purpose of cake washing is to displace the remaining liquid in the filter cake with another liquid (mainly water) or reduce the concentration of soluble chemicals in the solid matter of the filter cake. The application of utilizing the diaphragm filter plate technique will provide homogeneous porosity within the filter cake. The cake wash results are optimized by pre-squeezing the filter cake before the wash cycle has begun. The pre-squeeze step ensures a homogeneous filter cake and eliminates the potential for wash liquid flow channeling.

Filter Plates Design
Klinkau America, Inc. manufactures a complete line of diaphragm filter plates in Fixed Welded - Standard, Fixed Welded (Empty Chamber), and Replaceable Overhanging (Empty Chamber) Design. Diaphragm filter plates can be provided in sizes 470mm to 2000mm with and without stay-boss support in cake thicknesses up to 50mm (before squeeze). The Klinkau diaphragm plate product line can be supplied in polypropylene, polypropylene modifications, EP (santoprene ), and PVDF diaphragm material. Many thousands of Klinkau diaphragm plates in Fixed Welded - Standard, Fixed Welded (Empty Chamber) and Replaceable Overhanging (Empty Chamber) are in operation worldwide. Fixed welded - standard design US patent Nr The Klinkau fixed welded diaphragm plate product line includes corner or center feed arrangements. The Klinkau fixed welded diaphragm plate is manufactured with a center core body plate and two molded diaphragm sections welded to each side of the center core body to form the complete filter plate. The diaphragm have two defined hinge lines, i.e. one for the filtration phase and one for the squeezing phase; therefore risk of hinge failure has been minimized. The movement of the diaphragm causes bending stresses, which can adversely affect the diaphragm`s ability to resist chemical attack. The Klinkau diaphragm plate has been designed to counteract the bending stresses by constructing a `` flexible area `` instead of a `` flexible point`` to diminish the surface tension. Due to the ``flexible area`` design, the diaphragm can be constructed thicker than most standards. This design offers greater physical strength and resistance to chemical attack. The center core of the diaphragm plate is profiled to prevent the membrane from completely closing against the center core body. A distribution of the squeezing medium is possible through the whole area of the diaphragm at the beginning of the squeeze phase. This procedure guarantees a consistently even movement of the diaphragm. The diaphragm is supported by the center core, i.e. it is supported inside to guarantee a controlled and gentle diaphragm movement during the filtration phase. The well-rounded contour of the diaphragm allows unhindered movement of the diaphragm and better cake release. The diaphragm plate can be supplied as an ``ALL`` diaphragm plate stack arrangement or as a ``mixed pack`` arrangement (diaphragm plates alternated with recess chamber or flush plates). Klinkau GmbH + Co. developed the ``mixed pack`` arrangement in 1982 to provide an alternative solution to lower initial capital investment costs of the diaphragm plate package by approximately 25% without affecting the performance results. Fixed Welded - ``Empty Chamber ``Design US Patent Nr. The Klinkau ``Empty Chamber`` Diaphragm Filter Plate design was the next evolutionary advancement in polypropylene filter plate technology. Many filtration processes differ in solids content and filtering characteristics that may cause the risk of uncontrolled filling of the chamber. This uncontrolled chamber filling during the pressure filtration stage and/ or differential pressures may initiate insufficient chamber fillings or empty chambers. Subsequently, the risk of damage to the diaphragm is quite possible. The goal of the ``Empty Chamber`` design was to take the risk out of premature diaphragm failures. The ``Empty Chamber`` design was developed so the diaphragm would be adequately supported not only during the pressure filtration filling phase but as well as squeezing into the empty chamber. The design prevents an overstretching and consequently prevents damage to the diaphragm. In 1991, the Klinkau organization received US- Patent Nr. 5.021.155 -Europe-patent Nr. 3 482 662 for the development of the ``Empty Chamber`` design in welded design. Replaceable diaphragm - ``Empty Chamber`` Design All of the advantages and experience of the many thousands of welded Klinkau diaphragm plates in operation were retained in the development of the Klinkau replaceable diaphragm plate. The Klinkau replaceable diaphragm plate is a membrane plate in the ``Empty Chamber`` design with customer requested feed eye arrangement. The diaphragm plate is supplied with a center body plate installed with full gasket sealing around the sealing surfaces and filtrate corner holes. The replaceable diaphragm are easily installed to the center body plate with stainless steel retaining rings and block/clip attachments for the top and bottom of the plate. The design is available with or without stay-bosses and allows unrestrictive movement of the diaphragm. The diaphragm can also be supplied with other core body plates such as ductile iron, aluminum, or stainless steel. The replaceable diaphragm plate system incorporates diaphragm plates and companion recess chamber plates in the ``Mixed Pack`` design. The Klinkau replaceable diaphragm has specific strength in the area of the sealing frame to take the closing pressures of the filter press. The diaphragm has rubber-like flexibility in the piped areas of the filter plate. The diaphragm can be easily replaced in a few minutes even after years of operation without taking the plate out of the filter press. The Klinkau replaceable diaphragm plate can be used in any application where high filtration and squeeze pressure rates (up to 450psig) are required

Recessed Chamber, Plate/Frame Filter Plates
The most commonly utilized filter element is the fixed volume recessed chamber filter plate. The recessed chamber filter plate originated from the plate and frame filter plate when polypropylene became the material of choice due to relative low initial cost, excellent chemical and corrosion resistance, and light weight handling. Recessed Chamber Filter Plates Recessed chamber filter plates are manufactured with a fixed volume recess depth and area formed on both sides of the filter plate. The application and plate thickness will dictate the necessary quantity and size of stay-bosses required. The outside sealing surface of the recess chamber plate and stay-bosses are machined parallel to seal when the plates are pressurized and to minimize the wear on the filter cloths. The recessed area of the chamber plate is usually molded with conical pips. The surface of the pips provides support for the filter cloths and the gaps between the pips provide a drain path for the filtrate to exit to the filtrate discharge port. The recessed chamber plate can be supplied with customer requested feed eye arrangement. The recess chamber filter plate can also be supplied with a sealing gasket on one side of the plate and a caulking groove for the filter cloth to minimize wicking and leaking of filtrate from the plates. Klinkau America, Inc. manufactures a complete line of compression molded virgin polypropylene recessed chamber plates in sizes 250mm X 250mm to 2000mm X 2000mm. Special recessed chamber plate designs include high volume capacities, feed eye grommets; center support feed rings, polyvinylidene fluoride for high temperature applications, co-polymer resins for cold temperature applications, caulked and gasketed design, etc. Advantages of Recessed Chamber Filter Plates vs. Plate and Frame Filter Plates Maximum feed pressures to 300psig-20 bar lead to higher cake solids Easier cake discharge leads to faster cycle times Increased feed eye size allows faster filtration rates Increased feed eye size allows higher solids filling Gasket ( cgr ) design plates eliminate filter plate/filter cloth wicking Plate and Frame Filter Plates Klinkau America, Inc. manufactures a complete line of plate and frame type filter plates from size 250 mm to 1500 mm (12" to 59"). The early pressure filtration applications utilizing filter presses included the "plate and frame" type filter plate. Although not as commonly used in modern filter presses of today, "plate and frame" type filter plates are still the filter plate of choice for special applications. Typical applications include chemical (dye and pigment), mining (yellow cake and metals refining), industrial, and blood plasma filtration. Advantages of Plate and Frame Filter Plates Excellent cake washing capability Excellent cake air blow down capability Various cake thicknesses 10mm to 60mm Filter cloth can be easily changed Use of simple overhanging cloth Filter Plate Accessories Klinkau America, Inc. can provide a complete supply of handles (machined or injection molded), spigots (standard, two-way, three-way), and liner pipe connection systems (polypropylene and stainless steel).

Filter Plates Application
Klinkau filter plates are mainly utilized in the solid/liquid separation industry for polishing dewatering and filtration recovery The following list includes the major applications and industry users of Klinkau filter plates: Chemical Industry Application The Chemical Industry applications require different operating parameters for chemical resistance and extreme filtration characteristics. The Klinkau diaphragm plate product line provides a multifunctional solution for many extreme filtration applications. Many years of research and development, as well as years of testing in the field, have led to the design and manufacturing of the Klinkau diaphragm plate product line. The custom made Klinkau diaphragm plate provides maximum wash efficiency especially for complicated wash procedures. The filtration of chemicals at temperatures between –10 to 95 degree centigrade requires a careful selection of diaphragm resins. The ideal solution for many chemical filtration applications is the welded Klinkau diaphragm plate in the standard and "Empty Chamber" design with corner feed and no stay-bosses in the filtration area for optimum performance. Food and Beverage Industry Application There is a wide variety of filtration processes in the Food and Beverage Industry requiring the benefits of the Klinkau diaphragm plate product line. The Klinkau diaphragm plate technology has been successfully utilized in sugar and starch production, beer mash filtration, wine, juice, and wine lees filtration, wine yeast, dry active yeast and baker`s yeast production, cheese and dairy production, and palm oil fractionation. Sugar industry standards require a minimum of 70% solids in the cake and a maximum of 0.5% sucrose content remaining in the filter cake. This high extraction rate must be achieved with a minimum of high temperature wash water not exceeding the cake volume. Cycle times between 12 and 30 minutes in a 24 hour operation at temperatures between 80 and 85 degree centigrade require a durable filter plate to meet these extreme parameters. Thousands of Klinkau diaphragm filter plates worldwide are in operation under these requirements. This specially designed external top feed eye diaphragm filter plate provides excellent filtration and washes results. Beer Mash Filtration requires a bottom external feed eye inlet to enable a smooth filtration with very little oxygenation in the worst. The design of the filtrate channels allows a mutual flow direction of the wash water to optimize the consumption of wash water. The moisture content of the husks is kept at 55-78% based upon the squeeze pressure and time. Municipal and Industrial Water / Wastewater Treatment Industries Application Due to the EPA`s RCRA regulations and a more ecologically-minded public, efficient dewatering practices are required to process water and wastewater treatment sludge. Since landfill space is becoming scarcer and the disposal costs of land applying are increasing, the filter cakes are required to pass the "Paint Filter Test" as well as meet cake dryness and leach ability standards. Many applications for incineration require dry filter cakes to meet certain standards for fuel value to reduce incinerator load requirements. The diaphragm filter press provides the optimum results compared to standard dewatering methods such as belt filter presses, rotary drum vacuum filters, centrifuges, and recessed chamber filter presses. The diaphragm filter press provides the highest possible level of dewatering even with variable process parameters. The Klinkau diaphragm filter plate design will produce the highest cake solids content possible and meet all shearing strength demands with either polymer conditioned sludge or ferric-chloride/hydrated lime conditioned slurries. The wide variety of the Klinkau diaphragm product line can allow easy conversion of standard recessed chamber plate filter presses.

There are also Klinkau diaphragm filter plates in very special design and resin modifications operating in Blood Plasma Processing applications. Metals Refining Industry Application A recessed chamber filter press can be chosen for metals recovery applications utilizing a wash system to increase the product yield. Typical applications include intermediate and final refining steps of cadmium, zinc, decopperizing, repulping, recovery, and primary metals leaching. Ground Water and Soil Remediation Industry Application Beginning in the 1980`s, new government regulations required landfill management to process the leachate from the landfill, and industry to remediate contaminated soil and groundwater. Mining Industry Application Filter Presses are utilized in many mining operations requiring clarification and dewatering. Diaphragm Filter Presses can be utilized for dewatering coal tailings into a salable product as a high BTU value fuel. This 1500 mm x 2000 mm filter press utilizes a Klinkau Replaceable "Empty Chamber" Diaphragm filter plate system. Palm Oil Fractionation Application The complete Klinkau diaphragm product line (fixed welded –standard, fixed welded- "empty chamber", replaceable diaphragm - "empty chamber") has been successfully utilized for over 15 years in the fractionation process of palm oil filtration. Refined bleached palm oil is being cooled to approximately 20 degrees centigrade by the crystallization process to crystallize the saturated fatty acids. The crystallization suspension is then filtered utilizing the diaphragm filter press. The filtration process will yield the valuable oleon (filtrate) and stearin (filter cake). An evenly formed filter cake during the filtration phase and a uniform movement of the diaphragm during squeezing has a great influence on the separation of the oleon. The operation and results of the diaphragm filter plate system are a major economical factor in the fractionation process. The method of construction on the Klinkau diaphragm product line guarantees an even cake formation and therefore a defined squeeze result that produces high yield and quality product. The latest development is the special Klinkau anti-static diaphragm to eliminate electrostatic energy within the filter press.
