This is a General formula.
Applications vary as do the de-watering characteristics of products.
The following formula is for establishing volume (ft3) for most de-watering applications:

Density of wet filter cake = Specific gravity of wet filter cake X the density of water.
For filtration applications where feed solids are less than 1 %, the filtration area often is the controlling parameter rather than volume for these applications, contact Gemstone Equipment.
- Gemstone Equipment does not guarantee the volume, density, thickness or water content of cake as each application varies.
