Principal Applications

Gravity Drum Filters

Single drum filter units are available from 5 m3/hr up to 1200 m3/hr with filtration grades from 20-200 micron. These units are available in a number of configurations but all require the water input to be lower than 10 m head. The rotating drum gives a continuous refreshed filter area for the process. The waste is then discharged by means of an external spray bar (water used can be clean filtrate). Available fully enclosed or open frame for river mounting, these are highly flexible primary filter systems, which generally utilise a SS filter mesh, but are also available in SS wedge wire construction for coarser filtration grades from 1.0 mm-5 mm.

This technology can be provided with various options including vibratory discharge (for sticky contamination) variable speed dives (for variable inlet conditions) and hot water backwash (for greasy contamination).

Gravity Drum Filters are used in the following industries and applications:
