Biocarriers for biological water and wastewater treatment
RVT Process Equipment's Bioflow biocarriers are used for efficient biological water and wastewater treatment in biobeds, Moving Bed Biofilm Reactor (MBBR), at industrial and municipal wastewater treatment plants.
Wastewater needs to go through several treatment steps to become clean water and one of the most important treatment steps is the decomposition of organic substances by microorganisms. This process takes place in aeration tanks with biocarriers. Oxygen is added to the aeration tank to increase the growth of microorganisms. The function of the biocarriers is to provide a place for the microorganisms to grow and remain in the tank due to the biocarriers' large surface area. This in turn leads to an improved decomposition process of organic material.
The total surface area of the biocarriers varies depending on the model and size. In addition, the specific density of the biocarriers can be adjusted from 0.95 to 1.15 g/cm³, depending on customer-specific requirements.

Design features
- High specific surface area
- Bioflow 9 with its filigree structure has a very high specific surface area of 800 m²/m³. This type of biocarrier is used in wastewater processes with a relatively low amount of organic material. One example is the treatment of wastewater from fish farms.
- Bioflow 40 is suitable for water treatment processes with large amounts of organic material. The Bioflow 40 has a cylindrical shape and is very durable.
- The specific density of biocarriers can be adjusted from 0.95 to 1.15 g/cm³, depending on customer-specific needs. It is important to note that the actual density will increase as the biofilm builds on the surface of the biocarrier.
