Disc Filters are engineered for efficient operation year after year with practically no maintenance. Plastic rings stack together creating a cylindrical filter element. During filtration, the rings are compressed together effectively filtering the water and protecting the system from clogging. Works well as a stand-alone unit or combined to form modular filter batteries. Available sizes 3/4" to 6" with mesh (micron) ranges from 40 to 200.


Highly effective multiple disc ring design captures and holds more debris.

Low friction loss keeps ysstem costs down

Greater holding capacity of the rings vs. screen filters mean less frequent cleaning.

Rings are easily removed for fast cleaning without the need for scrubbing.

Color-coded disc rings make identification of mesh rating fast and easy.



Reuse/recycle/reclaimed water

Spray tanks

Wherever very effective removal of debris is required

Works well as stand-alone units or combined to form filter batteries

Product features:

1, Precise filtration, according to water requirements to choose filter discs with different precision, there are a variety of specifications, such as 20μ M, 50μ M, 100μ M, 130μ M and 200μ M. Etc.

2, High efficient backwashing, high speed and thorough backwashing, and finish it within 20 seconds.

3, Full automatic operation and continuous water supplying, that is in the stack of filter, backwashing alternate between working and backwashing, switch automatically between two states but with little pressure loss for system.

4, Standard: Standard modular system design, the user can choose as per requirement, flexible and strong interchangeability.

5, Nonstandard: Flexible to make full use of corner space, installation could be as per site but with little occupation.

6, Reliable operation and simple maintenance, hardly need no daily maintenance, components 100% go through testing and debugging, special tools is needless, spare parts rarely.

7, Long lifespan: High-tech plastic filter cartridges is strong, no wear, no corrosion, after years of practical industrial verification, effect of filtration and backwash will not vary as time goes on.

Filtration procedures:

1, Sewage flows into the filtration unit through water inlet

2, Water from outside into inside of disc filtration disc

3, Water flow through annular ribs in channel, particle whose diameter is bigger than its edge height will be intercepted, stored in the curve edge space, filtering disc and intervals of the shell.

4, Filtered water enters internal of the annular filter plate, then it flows out through outlet.

Operating state:

Filter disc under the action of spring force and the hydraulic pressure is close together. But when the water containing impurities pass it, the impurity particles will be trapped.

Back flushing state:

Control valve change the direction of water flow. When disc is loosened, the central nozzle will jet along the tangent, make the disc rotate, the hold back solid of plate will be washed out.

Design choice:

Each filter unit (4 ", 3 "or 2"), according to different raw water quality and different water accuracy requirement, generally is divided into four categories:

A, good quality water: The city tap water, from stable aquifer extraction well;

B, general quality water: Circulating cooling water, the precipitation treated surface water through effective precipitation and filtering completely;

C, poor quality water, water quality from poor aquifer groundwater extraction, through effective precipitation, but without the little or biological treatment of drainage, there are a large number of microbial breeding surface water;

D, very poor quality water: From dirty rich in iron or manganese of borehole extraction well, affected by rainstorms and without precipitation, surface water without precipitation and biological treatment of drainage. In order to ensure filter system better job status, class D need to improve water pretreatment a grade.

Material for equipment:

JY filter head made by enhanced polyamide plastic molding manufacture, anticorrosive wearing, can work under pressure 0.8Mpa. Filter plate material polypropylene plastics, seal for EPDM, inlet and outlet water and drain road for stainless steel material.
