The inside of the
Saniplus comprises of a
pressure chamber, which starts and stops the unit, and the
motor, which drives the stainless steel macerator blades and the
pump.
When the flush is activated, the water flowing into the
Saniplus
activates a micro switch in the pressure chamber, which in turn
starts the motor. The motor is sealed for life in oil filled
enclosure. A common spindle drives the impeller and the
macerator blades. The moving parts therefore are kept to an
absolute minimum. Water and organic waste matter, enter the
chamber and are reduced to slurry as the macerator blades rotate
at 3600 RPM. The centrifugal force causes the reduced solids to
be ejected through a grill into the container where it is picked
up by the impeller pump mounted beneath the motor. The pump
operates at 10 PSI and pumps the effluent upward to 12 feet
and/or 150 feet horizontally. Once the water is discharged and
the water level in the container goes down, the micro switch
deactivates the unit until the flush is activated again. A
normal operating cycle for
Saniplus takes about
15 - 18 seconds depending upon the discharge pipe run
configuration; power consumption is therefore minimal.
In addition to the toilet waste,
Saniplus will
also discharge gray wastewater from a variety of other sanitary
fixtures, such as: a hand basin, a bath, a bidet and a urinal.
When adding a bathtub, a base will have to be constructed, made
out of 2" x 8" on edge, to allow for the installation of a
P-trap and some gravity flow towards the pump unit.
The
wastewater from other sanitary fixtures is discharged into
Saniplus via two 1 1/2-inch inlets, on either
side of the housing. Either one or both inlets can be used as
required. The discharge elbow on top of the
Saniplus
can be turned either to the left or to the right, depending on
the discharge installation.
The
Saniplus automatically adjust the input
rate from other sanitary fixtures, always giving priority to the
discharge water of the toilet. Inlet valves operated by a simple
float mechanism achieve this. For example, if the bath is being
emptied and the toilet is flushed simultaneously, the inrush of
water from the toilet into the container slows down or stops the
discharge from other fixtures for a few seconds, until the waste
from the toilet has been dealt with. As the toilet water is
discharged and the level in the container goes down the float
valves open and the discharge from the other fixtures resumes.
The
Saniplus is designed to provide vertical
pumping up to 12 feet as well as a horizontal discharge,
therefore a simple ball non-return valve is incorporated. It has
now become possible to install a complete bathroom where
previously this would have been impossible or where considerable
capital equipment and structural work would have been necessary.
The water closet the
Saniplus is connected to,
uses much less water than a regular toilet, it uses 6 liters
(1.6 USG) of water per flush.
