Biological Filtration Media

Request Quote


IAS BioElements™ are an efficient biological filtration media specifically suited for use in recirculating aquaculture systems. IAS BioElements™ have high specific surface area per unit volume at 750 m2/m3 (229 ft2/ft3) and also a higher usable surface area than other biological medias on the market today. The advanced engineered media design will not compress, wedge or bind together and is also offered in proper density for each unique biofilter format.

IAS BioElements™ are used internationally in some of the largest and most advanced aquaculture systems in the world. As a leader in the supply of advanced water treatment technologies, Integrated Aqua Systems now offers IAS BioElements™ as a key component in our moving bed bioreactors (MBBR) and also separately in quantities to meet the requirements of small and large scale applications. Special packaging is available for specific market requirements.

IAS BioElements™ are available in 3 densities for 3 types of Biological filtration systems. Our light media has a density of 0.93 g/cm3 and is suited for up-flow style filters. Medium density media has a density of 1.00 g/cm3 and is used primarily in moving bed biofilters (MBBR) which results in considerable energy savings by requiring less aeration for proper mixing. Heavy density media has a density of 1.20 g/cm3 and is used primarily in down-flow fixed bed filters.
