BIOROCK® non-electric residential onsite wastewater treatment systems offer an ideal solution for domestic waste water treatment in Australia

The BIOROCK® systems are very compact and free from any blower or air diffusors. They don’t need any electricity for the treatment process, leading to minimal maintenance and repair costs, the lowest operational costs and the longest desludge intervals.  These unique advantages lead to significant costs savings for the user compared to conventional wastewater treatment plants, as the reliability of the system is maximized with no possible breakdowns thus no need for expensive spare parts.

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.

The best final effluent testing results in Australia

BIOROCK® wastewater treatment systems clean the sewage to an astonishing level of purity. Our residential wastewater treatment systems can be used anywhere where no water treatment works is available.

BIOROCK® also stands out as one of the most successful systems at the independent test facility in Rotorua, NZ. BIOROCK is certified to meet the secondary effluent quality requirements of AS/NZS 1547:2012.
