SODIS, which stands for Solar Water Disinfection, which is a way to purify or to disinfect the water without using any high technology devices (I really mean without any electronic devices!) but still, related to certain high technology concept. Sure you all are kind of curious and feel weird, why am I speaking of without any electronic device and yet using the high tech concept. Hereby i emphasize, what you need to focus is, the concept of SODIS.
You sure don't need my reminds that, water is the world most important elements to the human. Without water, we cannot do many things in our daily life (Don't need to mention anymore about the activities right?). But after decades and decades, the water quality in our world slowly degrades and became worst when there are lots of activities or accidents that happened which contributes to the water pollution. Making the water quality is no longer satisfy in certain country especially Africa's fellow residents.
Water area which been polluted can no longer be consumed, consumption of the polluted water could bring harm to the human or even cause death to the consumer. Therefore, SODIS is developed to overcome this water crisis on poverty countries.
SODIS is a simple technology which used to improve the microbiological quality of drinking water. In short, it use solar radiation to destroy the pathogenic bacteria and microorganisms. This technology is first introduced by EAWAG (The Swiss Federal Institute for Environmental Science and Technology) and SANDEC (EAWAG's Department of Water and Sanitation in Developing Countries) (What a pretty long department name!!!) since 1991.
I'll describe the method of SODIS at below, you can try to do some experiment on it ^_^:

- First, we need to find a water bottle, which is transparent and colorless. We need to proper wash both inside and outside of the bottle. And most importantly, the water bottle must be made of the material of PET (Polyethylene Terephthalae). Bottle which made of PVC (Polyvinylchloride) as main material cannot be used to perform this disinfection process.
Yes, that is all the procedure for disinfect the water. But need to remind you all that, not all type of water is suitable to undergo this process. Water which has been polluted to a certain degree is not fit to perform this disinfection action. Therefore, when you do this experiment, at least try to use "Not So Dirty" water. >_< here.
Water is one of the most important elements in our world. Without water, we will sure encounter difficulty in our daily life. You're lucky IF you're provided with guarantee clean water source, because there are much people in this world who fact difficulty in getting clean water everyday. Therefore we should help these people to obtain clean water in order to let them continue their daily life. Hope this crisis will be surmounted by the co-operation of all countries. Please give encouragement for people to help protect our nature.
