Answer 1

Question:-

Calculate the annual requirement of bleaching powder (30% purity) for treating 50,000 KLD water with a chlorine dose of 0.5 mg/l

____________________________

Answer :-

the chemical formula of bleaching powder is Ca(ClO)2, water + chlorine = H2O + Cl.

30% × 50,000 × 0.5

30/100 × 50,000 × 5/10

30 × 50 × 5

= 7,500.
