 We help choose the correct press

​ The following is important to consider when choosing/sizing a filter press:

  1. specific gravity of slurry - The specific gravity is the weight per unit volume (i.e. pounds/gallon) of a slurry and can significantly vary from application to application. It is used to accurately calculate the mass of dry solids per day to be dewatered.
  2. temperature of slurry - The temperature of the slurry is used to select the appropriate materials of construction of the filter press as well as to determine its operating parameters.
  3. volume/day - The volume of slurry generated per day is also used in the calculation of the mass of dry solids per day to be dewatered.
  4. wet cake density - The density of the filter cake varies from application to application and is used to accurately calculate the volume of filter cake generated.  The density of the filter cake is also used to advise if extra support is needed in the structure of the filter press.
  5. hours of press operation per day - The size of the filter press is also determined by the hours per day it can be operated. The cake from a filter press can be dropped 6 times per 24 hour period with a 4 hour press cycle. If the filter press is operated only 12 hours per day it can only run three 4 hour cycles which results in the size of the press being 2 times larger.
