How the System Works
The KiwiTreat system is connected to your house via a 100mm diameter sewer pipe, and a power cable for the pumps and alarm systems.
The package includes three tanks, and a drip-line which is installed into the disposal area. The treatment is done by utilising naturally occurring bacteria, which is found in all septic tanks, young and old.
Tank 1 Septic Tank
- Tank 1 is a typical septic tank.
- This tank is divided into 3 working areas.
- The first area is where the untreated sewage is received into the system, from the house. And this is where the treatment begins.
- Fats and oils float to the surface, and remain there.
- Inorganic material sinks to the bottom of the tank, and remain there.
- The organic solids are broken down by the resident bacteria, and the resultant liquid passes though a partition wall to the second area.
- The second area is the anoxic area, and here additional treatment by the same type of bacteria continues.
- KiwiTreat also uses this area to help reduce nitrogen in the total package.
- The third area is where a biological filter is installed.
- Colonies of bacteria build in this filter which continue to purify the liquid passing through this area.
- Also installed in this area is a variable flow restrictor which smooths out any large inputs into the the septic tank.
Tank 2 Aerobic Tank
- The partially treated liquid then passes into the second (aerobic) tank.
- This is where the treatment process becomes greatly enhanced. Another type of naturally occurring bacteria takes over the job. This bacteria requires oxygen to survive, this is done with a venturi and pump, and given the right conditions, the liquid is further purified very quickly.
- The liquid then moves through another partition into a settling area where the last of the microscopic particles are taken out of the process.
- By now the liquid has the appearance of clear water. When it reaches the outlet it moves into the third tank.
Tank 3 Holding Tank
Tank 3 is simply a holding tank from which the completed treatment is pumped out to the drip-line, on demand.
Drip-line is used with this system to ensure that the environmental impact to our living space is absolutely minimal.
