Discs Plate
Filtration System
"Automatic backwash filter" and "manual filter"
are two different kinds of the discs plate
filtration system. They are wildly used in
irrigation filter, drip filter, water filter,
reused water filter, circulation water filter,
cooling water filter, etc.

Advantage of Filtering System
|
Advantage
|
Characteristic
|
Constant filtering efficiency
|
As core element of
filter, the uniformity of groove style
filtering superposition piece reaches to
international first rate standard. The
filter is in effect for all kinds of
suspension impurity including inorganic
and organic impurity.
|
High efficiency backwash, energy and
water saving
|
The unit of backwash
will be finished for 7-20 sec only. In
general the amount of consumed water in
backwash is less than 0.5% of amount of
filtering water. For viscosity impurity,
high effective washing also be reached.
The suitable scope is wider.
|
Full automatic control, flow
continuously
|
The filtering and
backwash may be carried out at the same
time. The loss of pressure and flow rate
produced by automatic maintenance of
system is less. The backwash is carried
out in turn one by one and the others
work normally.
|
Low cost, reliable
and long service life System
|
The system
has been identified through
IS9002
international quality system. And all
the products are tested overall before
sold. It's almost without daily
maintenance, installation and convenient
operation, reliability transportation.

Principle of work |
|
Filter
element of superposition piece disk style
filter: The filtering superposition piece is a
carrier for the mixture treatment. It
superimposes by a group of a double-sided belt
different direction trench's plastic disk sheet.
While water passes through filtering
superposition piece, under the action of spring
and hydraulic the filtering superposition piece
will be pressed closely,
then they'll form numerous crossing of
superposition piece. And impurity granule will
be withheld at those crossing. The width of
lamination is 12-14mm. It's made of high-quality
engineering plastic, high wear resistance.
Filtration accuracy depends on the depth and
number of grooves. (Principle explanation like
figure above) |
|
2.Principle
at filtering phase:
Stream will enter into the
inner of filter through water inlet of filter.
While water passes through filtering
superposition piece, under the action of spring
and hydraulic the filtering superposition piece
will be pressed closely and impurity granule
will be withheld at crossing of filtering
superposition piece. The filtered water will
flow out through main canal. At this time
one-way diaphragm valve is at open state. (Shown
as the right figure)
|
|
|
3.Principle of backwash phase:
While
the pressure difference reaches to certain value
or within the set time, the system will enter
into backwash state automatically. Controller
will control the valve to change the direction
of stream. The one-way diaphragm valve at the
bottom of filter will close main canal and water
of backwash will enter into the canal of four
-group shower nozzle. Water pressure in the
cavity of piston connected with shower nozzle
canal will rise. The piston will move towards up
and overcome the pressure caused by spring and
release the space of piston at the top of
filtering superposition piece group. Meanwhile
backwash water will eject along the tangential
direction of 35x4 shower nozzle above the canal
of four-group shower nozzle at high speed. It
makes the filtering superposition piece rotate
and separate. The ejecting water will wash the
surface of filtering superposition piece and
throw off impurity on it. While backwash is
finished, the direction of stream will be
changed again and the filtering superposition
piece will be pressed closely and the the system
will enter into filtering state.
