The Guardian SFB Rope uses silver to kill pathogens on contact.
SFB strands are covered with water permeable synthetic fabric
with a string attached to one end and used to pull the rope from
the container. Users put the Guardian SFB Rope into a 20 litre
collection container at the water source point, allowing it to be
treated on the way to the household. This technology was
especially designed for transporting source water. Virus and
bacteria removal is accelerated by the motion caused by carrying
the water. The Guardian SFB Rope also prevents water from
recontamination.
Can be purchased from the manufacturer upon request.
There are no moving or mechanical parts to break. Inlet water
needs to have low turbidity, total dissolved solids and hardness.
The Guardian SFB Rope has been laboratory tested by the
manufacturer and tested in the field.
If turbidity is higher than 30 NTU, filter the water and shake it
vigorously for 1 minute before using the Guardian Rope. If water
hardness is over 500 ppm, allow 50% more time for treatment.
The treatment effectiveness will be significantly reduced if the
Guardian SFB Rope comes into contact with chlorine products
(such as bleach).
The Guardian SFB Rope may corrode if placed in a metal
container with saline water. The Guardian SFB Rope should be
cleaned if this occurs.
