BIOROCK® was established in 1988 and is now an internationally acclaimed and experienced company and an industry leader in
(compact) sewage water treatment technology.
The BIOROCK Series is a range of compact sewage treatment plants, denominated into 4, 6, 10, 15 and 30 person (PE) systems. The revolutionary BIOROCK® sewage treatment plants use a biological process and are gravity fed, requiring no electricity or moving parts in the treatment process.
As a result of this, maintenance and operational costs are extremely low, and reliability is maximized. The durable HDPE tanks are produced and assembled in our own factory. The plants are supplied as a complete package for ease of installation.
The BIOROCK® system functions as a two stage treatment system.
Initially the raw sewage enters a primary tank to provide separation and the breakdown of organic solids (Primary Treatment). The sewage then passes through an effluent filter before discharging into the BIOROCK® unit which incorporates the well proven aerobic digestion process (Secondary Treatment) and filtration process (Tertiary Treatment). Where required the BIOROCK® units can be retrofitted to a traditional septic tank.
Traditional versus BIOROCK®
BIOROCK® provides a revolutionary and efficient system when compared with many of the other sewage treatment brands available today. The superb results produced by BIOROCK® have placed our systems in a leading position when compared with older & traditional techniques – such as Activated Sludge, SBR, and so on. So many systems on the market are characterized by their energy consumption, high maintenance costs, significant operational costs and a high volume sludge production which leads to frequent de-sludging.
