Calculation of Amount of Bleaching Powder Needed

Given:
Population = 1000
Raw water supply = 50 lpcd
Chlorine dosage = 2 ppm
Available chlorine in bleaching powder = 20%

Step 1: Calculation of Daily Water Requirement
Daily water requirement = Population x Raw water supply
= 1000 x 50
= 50,000 liters (or 50 m3)

Step 2: Calculation of Chlorine Demand
Chlorine demand = Chlorine dosage x Daily water requirement
= 2 ppm x 50 m3
= 100 g/day (or 0.1 kg/day)

Step 3: Calculation of Amount of Bleaching Powder Needed
Amount of bleaching powder needed = Chlorine demand / Available chlorine in bleaching powder
= 0.1 kg/day / 0.2
= 0.5 kg/day

Conclusion

Therefore, the amount of bleaching powder containing 20% available chlorine needed per day to chlorinate a raw water supply of 50 lpcd at the rate of 2 ppm for a population of 1000 is 0.5 kg/day.
