Arkal Disc Filtration Systems

Arkal Disc Filters

Arkal disc filter units are extremely reliable filters used to remove particulate matter from raw water sources. Synthetic filter discs contained in the disc filter unit are compressed during operation with the help of water pressure. The discs have thin channels that determine the micron level. When the discs are placed on top of each other, these channels form a very large number of filter layers that intercept each other. The water passing through these channels is filtered to the desired particle diameter. When the pressure difference between the raw water inlet and the filtered water outlet reaches the specified value (0,5 - 0,7 bar), filter unit turns into the reverse rinse mode automatically. The spring compressing the discs loosens during backwashing, opens between the discs and dirt (solids) that accumulates between the discs is thrown out with backwash water. Disc filtration systems are commonly used purification units for the protection of the following units by filtering the problematic waters containing sediments. Disc filter units are generally preferred by agricultural irrigation and drip irrigation systems applications. The filtration level can be chosen as 20 - 55 - 100 - 130 - 200 - 400 µ.
