OFFER & USE OF ACTIVATED FILTER MEDIA SYSTEMS IN AQUACULTURE
Pressurized AFM are rapid, and pressurized multi layer filters which are filled in with Activated Filter Media (AFM) by Dryden Aqua instead of sand to double the process performance. The AFM media offers 300 times more surface area than the sand media, is electrostatically charged to absorb organic substances and small particles and finally the metal oxide catalysts located on its surface make the AFM self sterilizing, as well. The developed filtration speed varies between 20-25m/h at a pressure rate of 2.5 bar. The specific filter configuration offers extra resistance to bio-fouling, to bio-coagulation and does not permit any unfiltered water to escape due to transient wormhole water channeling.
Our AFM filters are specifically designed to provide backwash operation, by reversing the water delivery to flow from the lower to the higher media layers collecting and discharging the deposited particulate matter to the effluent waste line. AFM vessels are fabricated using Bobbin Wound and to provide ozone osmosis protection they are coated by venilester layer.
AFM filters work with 50% less water flow compared to traditional sand filters. The media used allow long lasting usage.
AFM media maybe used for any pressurized vessel. MAT AFM filters are specifically designed and fabricated pressurized vessels for fish hatcheries, fish farms and other aquaculture applications.
OPERATION & ENGINEERING OF PRESSURIZED AFM
The wastewater is dispersed evenly over the Activated Filter Media by diffusers which are located on the upper part of the vessel. As the water permeates down through the media layers, the particulate material carried in the water is deposited to the Activated Filter Media (AFM). The AFM is manufactured from amorphous aluminosilicate glass, subjected to form a large nanostructure effective area. The metal oxide catalysts located on the media surface give a high redox potential making AFM media self-sterilizing, against undesirable microorganisms.
ADVANTAGES OF OUR AFM SYSTEMS
- More than doubled performance over a conventional sand filtration system
- Higher effective filtration surface than sand
- Secures Biodynamic Stability
- Limits untreated water escape
- Substantially lower chlorine oxidation needs
- 50% lower backwash water rate
- AFM media do not require replacing
- AFM is a Self-Sterilizing Media
- No bacteria growth, thus no bio-fouling & no bio-coagulation
