OSPRI makes SODIS even easier to use.
Standard SODIS treatment requires users to juggle multiple variables. With OSPRI, all it takes is a simple color change.
Step 1
Fill a plastic bottle with source water. Place OSPRI into the bottle.
Step 2
Place bottle in sunlight.
Step 3
The OSPRI will change color gradually during the SODIS treatment.
Step 4
Remove OSPRI from bottle. Store OSPRI in a clean, dry place. Enjoy clean drinking water.
Let's compare the standard SODIS protocol to enhanced SODIS with OSPRI.
Standard SODIS
- ☑ Ensure the bottle is made of the right material.
- ☑ Make sure the bottle material is not too thick.
- ☑ Make sure the bottle is not too big.
- ☑ Check that the water is not too cloudy.
- ☑ Estimate the percentage of cloud cover and use it to calculate the treatment time.
SODIS with OSPRI
- ☑ Did the OSPRI change color? If so, the water is safe to drink.
That's all.
