JY disc filtration system

• Application

l         Particle filtration

l         Prefiltration before deep water treatment process

l         Membranes, cartridges and media filters protection

l         Nozzle protection

l         Cooling water filtration

l         Boiler feed water filtration

l         Water recycling and effluent recovery

• Features

l         Accurate filtration: various micron-precise disc choices for different water condition, including 20µ, 50µ, 100µ, 200µ.

l         High efficient backflushing: high-speed and completely backwashing in approximately 20 seconds.

l         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.

l         Modular filtering unit design: Standard modular filtering unit design makes the system flexible and exchangeable at user’s requirements.

l         Flexible system design: flexible and compact design suitable for any place or corner space

l         Reliable operation and easy maintenance: almost no day-maintenance, 100% factory tested and operated, no tools required, few spare parts

l         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.

  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: 4-75℃

PH: 4.0-13

• 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.
