Biofiltration Media

Over the years there have been many weird and wonderful designs of biofiltration media, 

in the end however, industries keep coming back to the standard, proven designs below. 

This is because they offer the best mix of surface area, void space and value. 

There are three types available, Rs, Rm and Rmp are random pack media (ie individual pieces which fill the biofilter), FM a media specifically designed for fluidised filters and SM which is a structured media (ie consists of corrugated plates 

welded together to form a free standing structure).

Trickle Filter Media - RMP

We have successfully used this range of media in a variety of biofiltration applications. It is light weight, suitable for trickle filter applications and has a high void space, resulting in minimal channeling and maximum performance. It is chemically resistant to a wide range of aqueous solutions, acids, alkalis, oils etc.

Fluidised Filter Media - FM

FM biofilter media is specially designed for fluidised filters. Made from polypropylene it has density very similar to that of water and has a neutral buoyancy. In addition to making an ideal fluidised media this also prevents the media "packing" should the fluidising system (which may be water or air) fail. This media is by far the most successfully used fluidised media in aquaculture. The media is black in colour.

Submerged Filter Media - SM

SM biofilter media is a structured media. Until now such media’s have been too expensive for aquaculture, however, recent advances in production technology for such items, has meant that the price of the media has come down significantly over the last 12 months. The structured nature of the media allows very simple installation and backflushing (should it ever be required).

Degassing Media - RS

RS media is similar in design to the trickle filter media (RMP) but is approximately twice the diameter.  It is light weight, has a high void space, resulting in minimal channeling and maximum performance. It is chemically resistant to a wide range of aqueous solutions, acids, alkalis, oils etc. the media should be used in conjunction with a spray bar to distribute the water as evenly as possible across the filter.
