Therefore it is recommended to filter chlorinate the water before and after application of chlorine should be mixed well and allow to stand 30 minutes for the chlorine contact microorganisms.
Drinkable water with iodine:
This is very effective disinfectant to kill bacteria, viruses and other microorganisms that can be found in water.
