Dear Eduardo,

I fully agree with the points raised by Joseph Cotruvo,

From my personal experiences, I would not go with using UV for disinfection of rural waters, its expensive and required professional work to operate and maintain, I assume you cold look for another cost-effective alternative

It would be good if you can analyze the raw water to identify the man constituents, and based on that we can suggest another treatment options rather than UV technology

I might suggest to use available natural materials from the project area such as natural coal/ sand Coal mixed in fixed bed form. Such beds will help in reducing nuisance odors/ irons, other dissolved solids and also microbiology from the raw water. The effluent from the fixed bed system can be disinfectant using any other proposed technology like chlorine, or UV . if this might be good option, please contact me and we will discuss further (zrashdan@yahoo.com)

Best wishes

I agree with you, but using filter bed before applying uv or other disinfection tech will help in reducing costs of the UV system 

If you already have some analysis for the raw water please share it with us so we can assist him in better way

Yes, I agree. That's why we keep in mind the possibility to incorporate sand filters (to reduce turbidity) and chlorine pulses or reduced continuous injection.

Thanks

Filters are useful to separate particles as smaller than clay, protozoa, and maybe some bacteria, but has no effect to all bacteria and viruses, where disinfectant chemicals (or radiation) are needed, that's why we are looking for alternatives to.

Thanks for your opinion.
