The first compact sewage treatment plant in the World without electricity and moving parts

The BIOROCK® S series is a range of compact packaged sewage treatment plants, denominated into 4, 8, 12 & 25 person systems. If installed in parallel they can also cater for greater population loadings.

BIOROCK® S Series system functions as a two stage Sewage Treatment Plant. The raw sewage first enters a Primary tank to provide pre-separation and initial breakdown of organic solids. The sewage then passes through an effluent filter before discharging into the BIOROCK® unit itself which incorporates the aerobic filtration process.

This later stage of the process is defined by layers of BIOROCK® media. The BIOROCK® media is pre-treated 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.

Where required the BIOROCK® S Series can be retrofitted to a traditional septic tank to provide secondary effluent quality.

BIOROCK® provides a cutting edge modern solution that ensures an ecologically superior sewage treatment solution! The results delivered by BIOROCK® ensure our leading position in the market & environmental forum in comparison to older & traditional techniques – such as Activated Sludge, SBR, and so on. These latter traditional systems are characterized by their energy consumption, high maintenance costs, significant operational costs and a high volume sludge production and accordingly, sludge management.

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.)
