Question on the biocide additive for the Katadyn PUR Survivor 06 and 35 Reverse Osmosis Manual Desalinator Pumps:

Is the biocide to kill organisms in the freshly pumped water or is it to protect the unit itself?

If it is to kill organisms in the freshly desalinated water, what is the biocide?

Could one use the biocide for other non-desalinating systems or even manually?

If unable to use the biocide, can you run the desalinated water through a conventional filtration with or with out a silver or iodine system to achieve the same results as the biocide?
