Process Description
Shongololo Waste Water Treatment Plants use the latest biological technology and equipment for superior strength and simplicity.
The biological process of waste water purification has been perfected over millions of years by nature and has been mimicked by humans for hundreds of years.
The process starts by the gravity inflow of all domestic black* and grey water of the premises into the first underground sealed plastic chamber of the Shongololo
1. Septic Chamber
Solids are separated into lighter particles that will float and heavier particles that will settle. The relatively clearer water from the middle of the chamber then overflows to the anaerobic chamber.
2. Anaerobic Chamber
Further settling takes place as well as the breakdown of BOD (biological oxygen demand) through anaerobic bacteria, which thrives in this environment that is void of oxygen. Up to 40°/o of the BOD can be removed in this stage alone. The waste water stream then flows into the biological reactor chamber.
3. Biological Reactor
The perfect environment is created for natural bacteria to proliferate and consume the organic waste in the water. Specialized plastic floating bio filter media is used to increase the surface area for bacteria to live. To put this in perspective - 1 m3 of this media has a surface area of 2 tennis courts.
Oxygen is added to the waste water via a propriety bubble generation system to create the ideal aerobic environment for the ecosystem to thrive and to lower the BOD of the waste water. After sufficient contact time the water then overflows to the final sanitation and discharge chamber for further treatment.
4. Discharge Chamber
The water in this chamber is sanitised by a chemical
free process of using ozone or alternatively mineralisation to eliminate the pathogens. The clarified, sanitised, odour-free effluent is finally pumped on demand to irrigation, re-flushing of toilets or many more reuse applications.
* Black water is sewage from toilets. Grey water is waste water from sinks, basins, laundry, showers, baths etc.
