Disc Filtration System
DISC FILTRATION SYSTEM
Application
Particle filtration
Prefiltration before
deep water treatment process
Membranes, cartridges
and media filters protection
Nozzle protection
Cooling water filtration
Boiler feed water filtration
Water recycling and effluent
recovery
Features
Accurate
filtration: various micron-precise disc choices
for different water condition, including 20µ,
50µ, 100µ, 200µ.
High efficient
backflushing: high-speed and completely backwashing
in approximately 20 seconds.
Automatic
operation and continuous supply: There are several
filtering units in a filtration system. While
a single unit is backwashing, other units are
still working and ensure the continuous water
supply and negligible pressure loss. The system
can automatically alternate in filtering or backwashing
mode.
Modular
filtering unit design: Standard modular filtering
unit design makes the system flexible and exchangeable
at user's requirements.
Flexible
system design: flexible and compact design suitable
for any place or corner space
Reliable
operation and easy maintenance: almost no day-maintenance,
100% factory tested and operated, no tools required,
few spare parts
Durability:
High-tech strong filtering cartridge ensures no
wear and tear, no corrasion. Through approved
years industry application, there is no deterioration
of filtration and backwashing performance.
System
Configuration
JY Series disc filtration system
is to parallel several filtering units.
The basic configuration:
JY 2-3 ~ 5 ---- 3 ~ 5 pcs of 2" filtering heads
JY 3-3 ~10 ---- 3 ~ 10 pcs of 3" filtering heads
Working
principle:
JY Filtration system includes two type of basic filtering units:
JY2, JY3. The filter is comprised of the grooved discs.
The junction of the groove of one disc with the adjacent disc
can retain the solids in the water.
Disc filters provide in-depth, three-dimensional filtration
using stacks of compressed discs.
Material:
JY filtering heads are made of reinforced polyamide. No wear
and tear, corrosion resistance. The max working pressure can
be 0.8Mpa. The material of discs is polypropylene. The seal
is EPDM. The inlet, outlet and drain manifolds are all made
of stainless steel.
Filtration
Process
The filtration discs are tightly compressed together by the
force from the spring and hydraulic pressure to retain the
particle in the feed water.
Backwashing
Process
An controller activates the valves to reverse the flow direction.
Then the hydraulic pressure on the piston changes direction
and discs are released. Nozzles located at the center of the
disc element spray tangential jets, causing the discs to spin
and the retained solids are flushed out.
Technical
data:
Operating pressure: 0.08-0.8Mpa
Backwashing pressure: 0.15-0.6Mpa
Backwashing time: 5-20 seconds, adjustable
Volume of backwash for each filter head: 30-100 liter
Pressure loss: 0.001-0.08Mpa
Working temperature: 4-75º
PH: 4.0-13
