Couple of quick questions.

1) Why RO? Why not employ microfiltration? The main contaminant in rural communities will be bacterial, and microfiltration will address that, lasts longer and costs less. It seems like RO is over treating the water.

2) On overtreating, this system treats to the point of un-usability. How would you propose to reintroduce minerals and electrolytes into the treated water in your system? Without those, RO treated water is undrinkable.

3) By what metric do you have an RO system that cost only twenty pound?

4) Or an RO membrane that will last a whole year, filtering 50L per day? That is nowhere near enough for a reverse osmosis system.

5) Is there any pretreatment or screening process before the RO membrane in order to filter out particulate matter that would otherwise punch holes in the membrane? Without that the membrane will be shredded.
