Choosing the right size filter pack for your press is crucial to having an efficient dewatering system and preventing future maintenance issues. We want to help take some of the guess work out of selecting the right filter pack for your dewatering needs. So when you start down the decision making path make sure you consider the following:
Consider how substantial your dewatering needs are. Do you have so much slurry to handle that the press will need to be running 24/7 or for just a few hours a day? Operating hours determine how many times a press cycles and how long those cycles last. Most importantly, it helps determine the size of the filter press.
2. What volume of slurry will you be dealing with?
And we mean volume in the mathematical sense, which is total volume of liquid/solid suspension to be filtered during the daily hours of dewatering operation expressed in GPD (l/d).
Or to put it in more plain language, how many gallons of slurry need to be dewatered and how many pounds of dry solids need to be produced per day.
Once you have this number you can decide if a large capacity or a small capacity filter press is the best fit for your dewatering process. Our small capacity J-Press® filter presses can dewater between 25 gallons and 1,000,000 gallons of liquid per day, and our large capacity presses much more than that.
3. How many chambers will you need to handle that amount of slurry?
There is a simple formula that can be used to answer this question:
filter press volume / volume for 1 intermediate plate = number of chambers required

Let's say that you purchased your press a while ago and you need to update your filter pack, because maybe you didn't pick the right size the first time, or your dewatering needs have changed; keep the following facts in mind:
1. You CANNOT safely take any plates OUT of your filter press.
2. However you can expand your press and add more plates, depending on:
The amount of open space left in your press
How much clean-out space you want to sacrifice
If your press has an expansion piece
