Diatomaceous Earth D.E. Filter Candles For Beer Filtration System
What is a D.E. Filter ?
The Diatomaceous Earth (D.E.) filter contains filter elements that
have wedge wire screen candles. They are covered in a fabric on
which the D.E. forms a coating. The D.E. acts as a filter by
permitting water or beer to filter through the D.E. and leave the
impurities behind. The D.E. filter has the ability to filter out
Here is the D.E. filter candles details.
It is made of wedge wire screen parts and end fittings.
According to different filtration system design, The fittings are
Also ,the length, and filtration slot size are normally different
Self-cleaning candle filter is a high-tech filter system, Consisting of vertically positioned
filter candles in a vertical tank. The filter candles is made of
316L Stainless Steel. The candles are installed in several
manifolds having individual filtrate outlets. The filter medium
that is used to cover the filter candles can be chosen such that a
clear filtrate is instantly obtained.
The liquid to be filtered enters the vessel and flows from the
outside to the inside through the filter candle. The filtrate flows
down to the bottom of the candle and rises through the central tube
in the outlet manifold. The particles are collected on the outside
of the filter cloth and form a regular filter cake.
After Drying the filter cake, The cleaning is done by a back-wash
or a back-pulse with air or inert gas. The backpressure blows up
the filter cloth and brings the filter cloth-in the original
circumference. The pulsating backpressure opens the mesh of the
cloth resulting in a very thorough cleaning. Because the filter
candles are positioned on seperate manifolds, They can be cleaned
one manifold at a time. This decreases the quantity of air or inert
gas required and assures that the filter cake is evenly discharged.
As an alternative, the filter cake can be discharged as slurry so
it can be returned to th process or used for furthre processing.
