JY Disc Filter

Improve and enhance traditional disc filter
1. Use many patented technologies, much safer, high efficiency, save water, save space and less routine maintenance for installation and application.
2. Filter cartridge design without spring, while in filtration, the inlet water pressure compact the set of discs by the diaphragm device automatically, thus pressure required for backwash is decreased greatly.
3. Unique build-in duckbill valve, ensures the maximum water capacity during filtration process, as well as has greater backflow check valve function while backwash process.
4. Split assembled filter cartridge structure, is flexible to change filter cartridge height as design required, thus adjust filtration area, and meet different system matching requirement.
5. Give up conventional metal clamp design, filter unit with self-locking buckle and specially designed seal ring, assembling and disassembling of the filter unit cover becomes very easy, good sealing effect.
6. Every filter unit has filtration and backwash process indicating devices and automatic air intake and air discharge devices, prevent water hammer damaging as well as improve filter cartridge backwash result.

Model selection
1. Raw water quality categories:
A. Good: Municipal tap water, well water extracted from stable aquifer
B. General: Cycle cooling water, surface water after sedimentation, effluent water after effective sedimentation and full biological treatment.
C. Poor: Underground water extracted from poor quality aquifer, effluent water after effective sedimentation, none or seldom biological treatment, surface water with large quantity active microorganisms.
D. Very poor: Dirty well water or well water containing high iron and manganese; Surface water affected by flood and without sedimentation, drain water without sedimentation and biological treatment.

Different raw water has great effect on filter' operation cycle, generally choosing a system mold ensuring each filtration process can last more than an hour.

Filtration grade selection:
Selecting discs, it is significant for ensuring filter's application through the whole water treatment process, only if selecting discs correctly, post water quality requirement is met. The following table is recommended filtration grade for common application.

Filtration system application Filtration grade selection
Drinking water pretreatment, various production process water, nozzle protection 50μ
Recycled water filtration, water supply pre treatment 100μ
Reclaimed water treatment, waste water treatment 200μ

1. Raw water quality, filtration grade and flow rate are the basis for choosing our filter system
2. Filter unit's flow rate refers to flow rate/pressure deviation curves.
