To start water treatment; it is necessary to store our raw water in a tank with a capacity of 1 to 000 liters; This water to be purified must have a minimum concentration of chlorine in order to avoid the proliferation of microorganisms. For this, chlorine tablets are added in sufficient quantity. chlorine kills most of the bacteria; fungus; virus; spores; protozoa and algae present in the water. it is not necessary to add a lot of chlorine; a concentration of 2 ppm is sufficient to kill bacteria and inactivate viruses; after a minimum reaction time of 500 minutes. If the source water is from a public network, it already comes with chlorine; so no need to add more.
