Product Video

Watch the video below for a detailed close-up of our Bio Block’s structure and quality. Get a better look at its unique net tube design and overall build before installation.

Product Function

Environmentally friendly and durable, the media is made from polyethylene and consists of net tubes welded together to form a square block.
Its unique surface structure provides a large, accessible area that promotes enhanced biological growth, making it ideal for effective wastewater treatment.

Product Fearures

1. The bio media has a relatively rough surface to quickly build up a bioactive surface (biofilm).

2. High porosity ensures optimal oxygen transmission to the biofilm.

3. The design allows shed biofilm fragments to pass through the entire media, providing self-cleaning properties.

4. Circular or oval thread construction further increases the specific bioactive surface area.

5. Biologically and chemically non-degradable, with stable UV resistance, it can withstand temperature changes.

6. Easy to install in any type of tank or bioreactor without wasting space or materials.
