The Unique Biorock Media

Low Maintenance Wastewater Treatment Plant
Eco Friendly Wastewater Treatment
Inorganic wastewater treatment

This later stage of the process is defined by layers of BIOROCK media. The BIOROCK media is pretreated with enzymes in order to achieve rapid start up and to stimulate the growth of the correct bacteria type. These bacteria colonize the media in vast numbers and rapidly digest the organic waste.

The treatment philosophy has been developed around a combination of aerobic/anoxic biological degradation and filtration. The BIOROCK technology advantage is further characterized by - minimal maintenance requirements & ability to handle intermittent (seasonal) loadings. (E.g. Holiday homes, Safari Lodges, Camping Sites, etc.)

Our exclusive media is degradation-resistant, stable and sustainable - keeping the purification system working effectively over the long-term. You will exclusively find it in Biorock systems

The acquisition cost of the MULTIROCK solution is particularly competitive. The savings in the purchase of the product are complemented by those related to the operating costs of the MULTIROCK line, which are among the lowest in the market. Running without electricity, and therefore free of mechanical parts which are synonymous with heavy maintenance, the MULTIROCK system allows its user to realize substantial savings in terms of both energy consumption and system maintenance.

Exceptional Purification Results

MULTIROCK is extremely efficient in terms of domestic wastewater purification and has proved to be one of the best performing systems on the market.

Our eco-friendly wastewater treatment plant consisting in several ECOROCK-5010 installed in parallel complies with European regulations for the treatment of domestic wastewater, and allows for the treated effluents to be discharged directly into the natural environment. (You should make enquiries with the local district authorities in order to find out the local regulatory requirements on using the effluents for irrigation purposes.)

Septic Tank Retrofit

If you already have a functionning septic tank, and just want to upgrade it, our ECOROCK treatment unit is the perfect solution. It fits most of the primary tanks on the market and will complement your septic tank perfectly.

Our new Multi-Way Splitter ensures that the pre-treated wastewater is consistently distributed across the ECOROCK-5010 Units.
