FUNCTIONS OF THE BIOZONE NOKAK SYSTEMS

In today’s world, the high cost and shortages of water and energy necessitate the provision for effective treatment of own water resources (such as on a Mine). Recycling of waste water using appropriate technology instead of discarding in to overloaded Municipal Sewer systems, septic tanks, drains and rivers is necessary, cost effective and safe. The use of septic tanks for sewer treatment is no longer condoned especially in built up areas and the use of chlorine as a disinfectant is definitely disallowed. In areas with high clay content soils, a high water table or sensitive groundwater areas, septic tank soak-away systems are inefficient, out of date, often fail and contribute to surface or groundwater pollution.

“Grey” (water from the home, excluding toilet water) and “Black”( toilet water) can all be treated suitable for reuse in the garden or for recycling. The Biozone NoKak sewage treatment plant treats the effluent on-site and produces clear, odourless and environmentally safe water for the irrigation of lawns, sports fields, golf courses and agricultural plots, or for filling dams where wildlife comes to drink, such as below a game lodge viewing platform, or simply to return it to the environment in streams, rivers or dams.

The Biozone NoKak systems enable natural and safe treatment of sewer and waste waterfor use in:

• Irrigation of gardens
• Replenishing of ponds or dams
• Safe discharge to rivers and streams
• Recycling to flush toilet or fire systems in homes, factories or high rise buildings
• Recycling to potable drinking water with further treatment.

Old septic tank systems need to be replaced with the Biozone system for effective sewerage treatment and recycling of waste water. Non domestic types of effluent such as chemical waste or the outflow from abattoirs and fish processing facilities can also be reclaimed with custom made Biozone systems.

FEATURES

The Biozone NoKak system uses a biological process where bacteria colonies are grown on a submersed fixed film media where they feed on organic nutrients (sewerage). Oxygen is introduced at the correct levels in to the treatment tank (bioreactor) to encourage and promote bacteria growth. In so doing COD levels are reduced, nitrification and de-nitrification
occurs and nitrates and ammonia levels are controlled rendering the water safe for recycling.

Once the bacteria mature they die and the Biozone system scours them off the media. This effluent passes into the clarifier where the sludge settles at the bottom and the clear water separates at the top. The clear water can then be sterilised by means of an ozone or ultraviolet technology. Once sterilised, the treated effluent is ready for discharge, either by
means of irrigation, or to return into dams or rivers. The accumulated sludge at the bottom of the clarifier is recycled back into the septic tank where it is digested further. If required, further treatment will be necessary to make the water suitable for drinking. The units are designed to suit the number of occupants using the water and toilet facilities. In offices and factories where occupants are only there during working hours, the sizing will be different to domestic homes and this must be taken in to account. (A normal household will use 250 litres per person per day). The Biozone NoKak systems are modular in design meaning that the treatment tanks are banked up to suit the application.
