Solar Water Disinfection (SODIS) in the Philippines

[MinaFem]

The leaching of DEHA and DEHP chemicals into the water is minimal and poses according to a recent study no harm for our health: As per WHO guidelines for drinking water quality it is well within the permissible limits and does not cause cancer or any other disease. For more information search for scientists Mr. J. Senthil Nathan and Dr. Ligy Philip.

Perhaps they could construct a huge plastic water container and just keep refilling it to have a steady supply of clean water without the cumbersome filling of individual bottles?

it only works with small bottles up to max 3 liters, but yes it would be cool if they could use a higher capacity :)

i heard reusing Bottles that may cause to Cancer,

So be aware and follow these methods.

If you have enough clean water (and soap) to properly clean out, and rinse all of the bottles each time before you fill them and set them in the sun, then how do not already have enough water that is clean enough for drinking just as it is?

They are using PET (PolyEThylane) bottles, and yes that might put harmful chemicals in the water after 6 hours under the sun's heat. An improvement to this - if you want to do it all perfect, would be to use glass bottles, placed on top of corrugated metal sheets. That would concentrate sunlight even more and thus increase the amount of UV radiation passing through the water. Of course, if these things are available.

It has been proven that there are 0 chemicals that are mixed in the water because of the PET bottle. Plus, using glass bottles makes it even harder for the UVA rays to pass through the bottle.

what´s the name of the music that start at 5.00 min? it's so amazing!!

[TheMaglev]

Is the container they are using are made of plastics???? Do they know that plastic has a chemical reaction when soaked up under the sun for so long and this reaction will be mix in the water inside the container, this can even cause cancer!!!

[megbobeg]

You're right of course, but in many places the chance of that happing is nothing compared to dying of cholera or dysentery.

@TheMaglev without water life generally comes to a terminal end after as few as 3 days

its a case of choosing the lesser (much lesser) of 2 evils
