A rotary drum filter (RDF) is a mechanical filter, which removes waste and other fine particles from the pond water via a micro screen (filter screen). What makes the RDF so special is the ability initiate an automated cleaning sequence by monitoring the water level inside the drum.
Rotary drum filters provide superb mechanical filtration with astonishing water clarity. Any waste from the pond water is removed from the water column almost immediately and it does not dissolve in the water. Therefore the workload for the bio stage is significantly reduced and allows filter chambers with a very small footprint.
We offer a range of rotary drum filters for fresh and sea water aquaculture applications. The filters can also be used in other industrial waste applications . The standard screen sizes available range from 30 to 90 microns. Our standard rotary drum filters have capacities of up to 420 m3/hr( 90 micron). All our rotary drum filters feature high quality German components including Siemens control panel and Grundfos pumps. Rotary Drum Filters require minimal maintenance and very low power consumption.
Fresh water and sea water models available – metal frame model for installation in a wet sump.
304 or 316L stainless steel corrosion-resistant frame
Polyester fabric screens, available in sizes ranging from 11 to 89 microns (special sizes are available).
Custom stainless steel mesh screens are also available
Optional backwash pump that employs filtered water to clean screens, eliminating the need for a clean, pressurized water source
Automatic backwash initiated by water level and/or timer
Quick-change spray nozzles for easy maintenance
NEMA 4X enclosure for controls
How the Rotary Drum Filter works
A rotary drum filter (RDF) is a mechanical filter, which removes waste and other fine particles from the pond water via a micro screen (filter screen). What makes the RDF so special is the ability trigger an automated cleaning sequence once the water level starts to drop. Therefore a rotary drum filter automatically adjusts to the waste intake and only flushes if necessary. The other big advantage of RDF’s is that all contaminant such as fish waste, uneaten fish food etc. would not remain in the pond water. Instead all waste is flushed out (removed) from the water column automatically after a very short period of time.
