Sewerage Systems

With Biozone purifiers we can process effluent and wastewater and convert it back to water. The Biozone plants are designed according to the specific requirement of each application – from industrial sites to local communities.

Biozone’s Biological Process

Our Biozone plants use the 4-SHIN Technologies to achieve its purpose

1. Nitrifica-shin 

2. Denitrifica-shin 

3. Clarifica-shin

4. Sterilisa-shin


  • STEP 1 – (Pump station) All effluent and wastewater gets collected in the Pump Station before it is biologically processed.


  • STEP 2 – (Bioreactor tanks) Bacteria remove nitrogen from waste-water by a two step biological processes: Nitrification and Denitrification.


  • STEP 3 – (Clarification tank) Once the bacteria mature they die and the system scours them off the media. These dead cells are collected and recycled back to the Pump Station. This allows the plant to generate zero sludge. The sludge settles at the bottom of the tank and the clear water is separated at the top.


  • STEP 4 – (Sterilization tank) here the clear water is treated either by Ozone or Ultraviolet and is now  ready for recycling.  Once sterilised, the treated effluent is ready for discharge, either by means of irrigation, or to return into dams or rivers.  If required, further treatment will be necessary to make the water suitable for drinking.
