Frame and Plate Filter Press is commonly used in filtration in industrial pharmacy...this animation provides further understanding to how it works!

2. Filtration:
*Term describes the process of removal or separation
between fluid and solid or fluid and fluid.
Darcy’s Equation:

3. Filtration Equipment:
*The press is made of 2 units:
a) Frame b)Plate

4. Filtration Operation:
Slurry
Filtrate
Slurry enters
the frame
from feed
channel! Filtrate drains
and escapes
from outlet in
the plate
leaving solid to
form a cake!

5. Cont. Filtration Operation:
Slurry
Filtrate
Frame
becomes
filled with
filter cake!

6. The process
stops, frame is
emptied &
cycle restarts!
Cont. Filtration Operation:
Slurry
Filtrate

7. Washing Operation:
In case the
solid cake is
wanted, the
cake is
washed!
Wash Water
Washings

8. Cont. Washing Operation:
To wash the

washing channel!
Wash Water
Washings
Water passes
through inlets in
washing plates to
cake and filter
cloth then
escapes from
outlets of
ordinary plates!

9. DisadvantagesAdvantages
*High labor cost.
*Used for slurries < 5%.
*Simple.
*High surface area.
*Provides effective cake
washing.
