A Plug & play Waste water / Sewage Treatment Solution 4 - 6 P.E


All-in-one, compact, integrated, Wastewater Treatment System. BIOROCK MONOBLOCK-2 is the perfect Septic Tank replacement.

BIOROCK MONOBLOCK-2  can cater 4-6 persons household- or commercial properties. BIOROCK MONOBLOCK uses no electricity (*) and is 100% environment friendly. BIOROCK MONOBLOCK-2 is a all in one system where the Bioreactor and primary tank are integrated in one plug and play unit. BIOROCK MONOBLOCK-2 is easy to install and requires almost no startup time after installation and longer periods of no-use. The high quality of the treated effluent produced can, when desired, be discharged into sensitive water courses.

Primary tank (first treatment)

The primary tank of the MONOBLOCK-2 has a volume of 2000 liter (2m3) and clarifies the sewage coming from the residence by retaining oils, fats and greases and organic solids. The water passes through an effluent filter before discharging into the BIOROCK reactor for further processing.

Bioreactor (secundary treatment)

The BIOROCK Media in the Bioreactor treats the wastewater naturally with an aerobic digestion process (Secondary Treatment) and a filtration process (Tertiary Treatment). The waste water / sewage water percolates through the BIOROCK filtering media. The BIOROCK Media is a very effective carrier material for bacteria. The BIOROCK media is highly resistant to degradation and remains extremely stable over a long term. The BIOROCK Media is easy to handle, is environment friendly ane 100% recyclable.

Revolutionary Technology

The MONOBLOCK units are packaged domestic waste water treatment / sewage treatment plants, providing a consistent high quality effluent that meets the highest standards. The biological purification technique requires no electricity or moving parts (*). As a result of this; maintenance and operational costs are particularly low, and the systems reliability is maximized. The units are assembled in light but durable HDPE tanks with lightweight, low profile, green access covers. The plants are supplied as a complete package for simple onsite installation. The BIOROCK units utilizes a unique fixed bio-film technology with specific functions to achieve an odor free effluent, suitable for irrigation or re-use in the grey water system. Due to the high quality of the treated effluent produced, should it be desired, it can be discharged into sensitive water courses.
