Hydrotech - Aquaculture Drum Filter
Drum filters are well proven when it comes to solid removal in aquaculture. We use the No. 1 drum filter: Hydrotech. With Hydrotech drumfilters nutrient loads can be reduced significantly.
Drumfilter models
Hydrotech drumfilters are available in many varieties: open filters with open inlet, with pipe connection, filters with tank, for all applications in fresh and sea water
This link sums up the different models:
Depending on the filter size and the mesh on the filter the flow varies from 5 up tp 1.000 l/s.

Drumfilters are used in a wide field of applications:
- Faeces removal in the effluent water of fish farms
- Mechanical filtration in Recirculating Aquaculture Systems (RAS). Microscreening enhances biological nitrification and increases the effectivity of UV and ozone disinfection.
- The use of 40µ drumfilters in RAS reduces the pressure from Ichthyophthirius multifilis (White spot)
- Sediment removal from the inlet water. Reduces solids sedimentation in the farm and gill problems
- Reduction of Saprolegnia infection with the combination of drumfilter and ozone in hatchery
- Algae removal in intake water from lakes
- Increase of dry matter content in sludge storage tanks
- Prevention of intruding of unwanted species into the farm
Advantages of Hydrotech drumfilters:
- Special structure of the filter panels: Even bigger particles are taken out of the water immediately: no grinding and leaching
- Up to even 20% more flow with the new generation of panels
- Different models allow perfect match to your farm
- Quality of material and manufacturing guarantees highest life time and performance
- Long time between backwash intervals due to high head loss in the filter
