Ostwald Filtration Systems GmbH is a manufacturer of filter presses and associated plant and equipment. Depending on the application we supply chamber filter presses or membrane filter presses. For the selection of the optimum filter press type OFS relies upon the extensive experience of its engineers. Decades of experience in the filtration of various types of suspensions with chamber filter presses and membrane filter presses makes OFS the ideal partner for your solid liquid separation task. Our philosophy is to provide our customers with an innovative and efficient process engineering solution, tailored to their individual separation problem, whilst ensuring low operating costs and a high standard of quality and safety. Our extensive knowledge of the chemical, food, mining and waste water industry will ensure the most effective selection and integration of the equipment into the overall process. What are the factors considered by OFS engineers in order to achieve the best possible separation result? Initially, the existing process data, combined with OFS’s experience, are analysed and the best filter press, chamber or membrane type, is selected. The size of filter press, which means filter volume and filtration area, is calculated. In selecting the size of filter press other important factors such as filtration time, speed of cake discharge and frequency and duration of filter cloth washing cycles are taken into account. Next the specification of the filter plates and filter cloth, with respect to pressure, temperature and chemical resistance, are considered. Following definition of the filter press the other plant components, such as feed pump, cake conveying system and process control system, are selected and integrated into the entire process.
In addition to the manufacture and delivery of new filter presses and plant equipment, OFS offers a wide range of service and upgrade activities. OFS provides Filter press service, contracts for preventive maintenance and tailor-made solutions for remediation, modernisation of machines and process upgrades to bring your plant up to a state-of-the-art facility. Conversions from chamber filter press to membrane filter press or adaption of existing conditioning systems are engineered to give the customer the most economic operation of his total installation.
