The system consists of a single, septic tank, with an integral biofilter,
clarifier to treat the effluent before discharge. A water supply is
not required as the system is charged with water on installation and
the displacement principle is used thereafter. It is a low-flow system
and suitable for the full daily use requirements of 6 adults. Excessive
use will degrade the effluent quality but in normal circumstances not
to a level which would be considered a pollutant or pose any health
or pollution risks.
in the system is a dropper tube and a pedestal with a closure system
to ensure the waste tank is sealed from the bathroom or toilet cubicle.
Men may use the system for normal urination without lifting or lowering
the seat. When the seat is lowered the closure panel opens and faeces
may pass into the tank. After use the seat returns to the open position
and the toilet aperture closes. As this is an anaerobic system urine
diversion is not required.
of anaerobic digestion in this system means that the waste is treated
and not merely stored. Anaerobic sludge will accumulate over time and
will need to be removed after 5 to 7 years of use. The clarifier/filter
section of the unit is simply lifted out and the sludge can then be
removed either mechanically or manually. At this time the clarifier/filter
unit can be cleaned and serviced if necessary.
can be installed inside a new house, an existing house or in a separate
cubicle depending upon circumstances. Should it be required to be installed
externally in a separate cubicle a purpose designed unit is available.
