How to use chlorine tablets for drinking water

Measure the volume of water to be treated.
Add 1 tablet for every 100 litres. For a 1,000 litre tank, add 10 tablets.
Let the tablets dissolve fully. Warm water or stirring speeds this up.
Wait at least 30 minutes before using the water, the contact time the World Health Organization recommends for chlorine disinfection.

Where to use

Drinking water and storage tanks: overhead and underground tanks, drums and public water supplies, including after floods.
Poultry, cattle and dairy farms: drinking water and water lines, sheds, cages, equipment and hatching trays.
Hospitals: floors, bed linen, surgical equipment and spills.
Hotels: floors, linen, utensils and pre-chlorination of RO feed water.
Aquaculture: equipment, nets and feed trays.

Why NaDCC tablets instead of liquid bleach

Accurate dose: each tablet releases the stated level of available chlorine.
No spills or leaks, and easy to store and transport.
Less corrosive to metals than liquid bleach.
Dissolves to a near neutral pH, while sodium hypochlorite is pH 9 to 12.
Stays stable for more than 2 years.

NaDCC tablets vs 0.5 g ISI chlorine tablets

Many 0.5 g chlorine tablets sold in India are IS 9825 tablets made with bleaching powder, which treat about 20 litres each. Super Active Chlor Tablets are NaDCC tablets that treat 100 litres each, so one pack of 1,000 tablets treats 100,000 litres of water. Compare tablets by litres treated, not by tablet count.
