How to read the Table.
There are several different methods in use for disinfection. When looking for a method which fits your purpose, it is best to start looking at the places of use (last row) you are planning to use your drinking water and see which properties your disinfection device needs to have.
It is always highly recommended to use a filtration step in advance of any disinfection method, as the particles and chemicals present in the water may have a negative effect on drinkability and disinfection process.
Chlorination
Chlorination is still the most widely used process for drinking water disinfection world-wide. Advantages are the low price of active chlorine and the remaining disinfection capacity long after dosing resulting in clean piping and storage tanks. Disadvantage is the difficulty in exact dosing and therefore often overdosing occurs resulting in bad taste and smell. This is especially true for small capacities in which case dosing measuring equipment is very expensive.
How Sensiblue compares to the other methods.
The Sensiblue is cheaper in operation, as it just needs salt to be added and more effective and reliable in killing bacteria and viruses. Secondly it is the only self-powered and self-controlling system meaning it is safer and easier to use. Lastly the fact that it does local disinfection with activated chlorine means that it has a longer lasting (residual) disinfection than any other known & proven method, which makes it perfectly suitable for local water storage.
Sensiblue has the closest resemblance to salt electrolysis, but given its patented technology - which makes it cheaper to run (no power needed) and safer in use (no high voltage, no dosing systems) - it is intrinsically safer than electrolysis and any other disinfection process.
The Sensiblue does not remove any particles or chemicals nor does it kill protozoa that are present in the water. As these substances have a negative effect on the disinfection abilities of the Sensiblue and drinkability of the water, we strongly recommend adding a microfilter (candle) with a minimum filter capacity of 5 µm in front of the Sensiblue (as with any other disinfection method).
