3. Filtration :-
INTRODUCTION :-
It may be defined as a process of separation of solids from a fluid by
passing the same through a porous medium that retains the solids but
allow the fluid to pass through.
The fluid that passes through is called as “filterate”
Filtration is the best established and most versatile method for removing
insoluble from dilute streams like fermentation broths.

5. PRINCIPLE :-
Vaccum or
Pressure can be
applied to
increase the rate
of filtration
It acts as a sieve
or strainer
It is based on a
surface filtration
mechanism
It is an apparatus
consisting of a
longitudinal
drainage screen
covered with a
filter cloth

6. The Filter leaf is
consisting of a
frame enclosing a
drainage screen or
grooved plate
The frame may be
any shape –circular,
square or
rectangular
The whole unit
being covered with
filter cloth
The outlet for the
filterate connects to
the inside of the
frame through
suction

9. WORKING :-
6. The air is passed in the opposite
direction which facilitates the
removal of cake
5. The cake is washed by
immersing the filter in a container
of water
4. Filterate enters the drainage
canal and passes through the outlet
3. Solid matter gets accumulate on
the cloth
2. The slurry passes through the
filter cloth
1. The entire assembly is placed
inside a container of slurry, and the
vacuum is connected to the outlet
