Question: What are the typical operating ranges of filter presses?
Keywords: v1i7,filter,press,capacity,limits,percent,solids
Answer: Filter presses are capable of handling fine solids are varying flow capacities. A couple of limits to consider may be:Up to 30% solids for flows up to 1 GPMUp to 10% solids for flows up to 10 GPMUp to 1% solids for flows up to 100 GPMUp to 100 ppm solids for flows up to 500 GPMThe chart shown below is helpful in understanding this and the operating ranges of some other types of filtration methods.Operating pressures of 100 psi are common, but 1000 psi is possible in some case. No specific information was available on the particle sizes that can be processed, but fine, powder particles are the most common.
