X1 = 0.054 kg or 54 grams hypochlorite granules
b. Weigh 54 grams of hypochlorite granules. Place adequate amount of granules in a suitable
container (e.g. mortar). Grind the granules using a pestle.
c. Transfer the ground granules in a beaker or plastic container. Add a small amount of water.
Stir the mixture to dissolve the granules.
d. Decant the liquid and transfer to a plastic gallon.
e. Add a small amount of water to the remaining granules in the beaker or plastic container and
repeat steps c and d until the required amount of liquid, which is 3.78 Kg is attained.
f. Transfer the remaining granules in the plastic gallon, replace plastic cap, and mix
thoroughly by shaking the contents. Keep the plastic gallon tightly closed.
2. Chlorinate the water supply
The amount of chlorine stock solution required to be pumped out to chlorinate a volume of water is
computed based on the flow rate of water that is pumped to the tank, or on the flow rate of water that
is released from the tank which is distributed to the different water lines to obtain 0.5 ppm chlorine
in the chlorinated water. The computation is as follows:
(C1) (V1) = (C2) (V2)
where: C1 = concentration of the stock solution (10,000 ppm)
V2 = volume of the required stock solution (unknown)
C2 = concentration of the required chlorine solution (0.5 ppm)
V2 = volume of water that is pumped to the tank or pumped from the tank based
on the flow rate of water (e.g. 500 gal/min or
1890 L/min)
