A BIO Block is a high-performance biological filter media used in wastewater treatment and aquaculture systems to support the growth of beneficial bacteria. These bacteria help break down organic waste, ammonia, and harmful pollutants in water.
BIO Blocks are commonly installed inside biofilters, moving bed systems, or biological treatment tanks to improve water purification efficiency.
How BIO Block Works
The BIO Block provides a large surface area where beneficial microorganisms can grow. As wastewater or aquaculture water flows through the media:
- Bacteria consume organic pollutants
- Ammonia and nitrite are converted into safer compounds
- Water quality improves naturally
