Matala filter media used in Aquaculture Filtration Systems
Applications in Bio-filtration:
‧Energy saving solids removal:
Swirl separator combined with top-layer of medium density Matala sheets.
Low density Matala sheets and medium Density Matala sheets in settling basins.
‧Nitrification:Design criteria 450mg TAN/m2/day
Most cost efficient nitrification can be obtained using High- or Super High Density Matala filter media beyond a high performance pre-filtration system
such as a drum screen filter or a belt filter.
‧Ecological balanced filtration system: Combined with a nitrifying filter an extra eco-filter can be designed using a combination of different densities of Matala filter media subjected to varying flow rates allowing for different populations of bacteria and plankton to be establish and stabilized the water quality.
Matala filter media in combination with natural filtration media.
Application of Matala filter media as a rooting substrate for aquatic plants.
‧Bio-filtration in Rotifer Cultures: Bio-filtration in continuous cultures or batch cultures of rotifers: High- and super High Density Matala filter media have proven to be the ideal filter media to retain flock and for nitrification.

Application in ponds provides Aquatic habitat combined with In-Situ Bio-filtration:
Thanks to its rigid tri-dimensional matrix structure, it provides:
  • an idea habitat for shrimp and fish to hide, rest and graze nature food.
  • excellent natural In-Situ Bio-filtration.
  • enhancement of the development of biofilm and plankton as natural food source.
  • easy maintenance of Matala in between cultures.
  • easy harvest.
Tests executed with Macrobrachim rosenbergii, Peneaus vanameii, Peneaus monodon and Tilapia sp. resulted in:
  • enhanced growth,
  • lower mortality,
  • reduce stress,
  • better health,
  • lower artificial feed consumption.

Type of Matala (Tube, Sheet, or coiled), density (degree of specific surface) can be chosen in function of age of fry and stocking densities in hatchery, nursery or grow-out tanks.

In-Situ Bio-filtration

Applications of Matala in ponds and tanks as spawning media:
The 3-dimensinal open matrix is idea for spawning, attachment and collection of eggs and secures a perfect flow of water through the media and oxygenation.
The rigid structure of Matala makes it possible to handle the eggs for eventual treatment.
