Bio Filter Media
High-efficiency bio filter media (MBBR media) supporting beneficial microbes, improving water quality, and enhancing aquaculture system performance.

Bio Filter Media

Our Bio Filter Media (MBBR medium) is the biological engine in modern recirculating aquaculture systems (RAS). This medium has been specially designed to provide the maximum effective surface area for the growth of beneficial microorganisms, thereby facilitating the rapid conversion of toxic ammonia (NH3) and nitrite (NO2) into harmless nitrate. By creating a stable and high-capacity biological environment, our medium enables higher stocking densities while ensuring the long-term health and sustainability of your aquatic animals.

Technical Advantages

Maximum surface area to volume ratio: The complex geometric structure of our product is designed to provide a wide protective surface area, thereby forming a dense and active biofilm layer.

Fast biofilm formation: Our unique material composition can facilitate the rapid attachment of nitrifying bacteria, thereby shortening the “start-up” time of the new biofilter.

Self-cleaning and low maintenance: The design of this moving bed enables the fillers to continuously move, thus avoiding excessive accumulation of the biofilm and ensuring stable water flow without clogging.

Importance of optimal porosity for oxygen transfer: The open structure can reduce head loss and ensure that oxygen and nutrients can reach the entire microbial population, thereby maximizing the filtration efficiency.

Excellent durability: Our medium is made of food-grade, corrosion-resistant polymers and is specifically designed to withstand wear conditions in freshwater and saltwater aquaculture environments.

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.
