EEvolved MBBR Biofilm Media
The type of Biofilm Media will have a significant impact of the success of an MBBR system. Each system is unique and may need a different geometry to promote healthy biological growth for its unique wastewater system.
SSI began producing its own media in 2019 to be able to have full control of the design and quality. Many medias on the market do not have sufficient density, strength, or quality control.
SSI media is produced to provide the best value to the customer.
Each media is made with high quality virgin HDPE, and is ensured to have the following qualities:
- Strength and longevity
- GEOMETRY
Proper buoyancy is important to ensure the media is evenly distributed throughout the tank. If the media is not evenly distributed, the water may short circuit around the media/biology resulting in insufficient treatment.
A media's bouyoancy is a result of the density and specific gravity of the material. if the specific gravity is too low (below .94) the media will float, which means that it will take a significant increase in airflow (to decrease the water density) to make the media mix uniformly thorough out the tank.
Our staff has seen systems with "light" media (about .92-.93 specific gravity) that requires 2-3x the airflow for mixing energy. This is a substantial operational cost. Buying media that uses the right material to have proper buoyancy may be a slightly higher capital cost, but it will be worth the investment as you will need smaller blowers (less capital cost) and less airflow (less operational cost).
