Disc Filters

Davey Disc Filters act as Depth Filtration and find a wide range of applications. They consist of a single or multiple housings. Each housing is provided with a stack of grooved discs plates kept compressed inside the housing. The wetted parts of the Disc Filters – such as the housings and filter discs are made from Engineering plastics and can handle high saline / TDS applications and rustproof.

The gap between the grooved compressed plates ensure bigger designated particles are filtered before inlet to application and the discs come with designated micron ratings. The feed flow from the inlet port is directed to the outside surface of the stacked discs where particles are deposited and only filtered water passes through. When the flow direction is reversed, all particles on the outer surface are dislodged and directed to the drain.

Disc filters finds a good application in UF plants. UF membranes need to be protected with an inlet prefilter – either as a basket strainer or DMF or Disc Filter, to prevent clogging of membranes with suspended particles. Disc Filters have the advantage of being compact, online backwashable, easily cleanable, rust proof, long lasting and a natural choice for UF Plants.
