About the BIOROCK Media

BIOROCK uses a material with huge surface area which allows colonization of the necessary bacteria, a process which is essential for the effective treatment of domestic wastewater.

The BIOROCK media is highly resistant to degradation and remains extremely stable over the long term - our 25 years’ experience in the industry being proof of this.
• Very stable inorganic material - does not break down over time, unlike “organic” media.
• Requires little maintenance – scraping and scarification is not necessary, unlike for organic media.
• The structure and composition ensures unsurpassed and unique surface treatment with exceptional purification results.
• Ecological material, locally produced and recyclable.

BIOROCK offers a much more efficient and ecological wastewater treatment technique compared to traditional techniques that are very high in maintenance and energy consumption.
