Biological Filter Media

High-efficiency biofilter media supporting beneficial microbes, improving water quality, and enhancing aquaculture system performance.

Biological Filter Media

Our biofilter media is specially designed for recirculating aquaculture systems (RAS), providing an optimal surface for beneficial microbial growth. It efficiently converts toxic ammonia and nitrite into harmless nitrate, stabilizing water quality and supporting higher stocking densities. Durable and corrosion-resistant, it ensures long-term, reliable operation for sustainable aquaculture.

Available in various shapes and sizes, including rings, balls, and sheets, the media can be customized to match different system scales and flow rates. Its high surface area and optimal porosity promote maximum microbial colonization while minimizing head loss, making maintenance simple and reducing operational costs for intensive aquaculture operations.

Product Specification

Explanation
A large amount of suspended biological carriers with a specific gravity close to that of water (i.e., what you call “filter media”) are added to the reaction tank (such as an aeration tank or anaerobic tank). Through aeration or stirring, these carriers are uniformly fluidized and tumbled in the water. As wastewater flows through the reactor, a biofilm rich in microorganisms grows on the surface of the carriers. These microorganisms decompose and digest organic pollutants in the water.
