| Helpful Information |
| GPM = Gallons per minute
at point of chlorine injection |
| RESIDUAL = amount of
chlorine remaining after contact with water and its impurities.
A residual of .2 -.6 PPM should remain after chlorination at point
of use. |
| CONTACT TIME - the
time required for chlorine contact to perform disinfection. |
| APPLIED CHLORINE DOSAGE
= desired chlorine feed rate for water conditions. See chart below. |

| Metering Pump Selection |
| Select metering pump by taking total
gallons or liters used per day (meaning 24 hours of well pump
run time), and selecting a metering pump that most closely matches
this requirement. For instance, if 2.4 gallons of chloirne are
needed per day, select a 10 gallon per day pump. Then set the
pump at 24% of rated pump by adjusting the speed and/or stroke
settings on the pump. |
| Impurities Affecting Chlorine
Demand |
| IRON:
Apply 1 ppm chlorine for each 1.0 ppm iron |
| MANGANESE:
Apply 1.7 to 2.0 ppm chlorine for each 1 ppm manganese. |
| HYDROGEN
SULFIDE: Apply 2.0 ppm chlorine for each 1 ppm hydrogen
sulfide. |
| OTHER
factors that can affect chlorine demand: color, sediment, turbidity,
oil to name a few. |
| Variable Flow Rates |
| Note: if the water stream into which
the chlorine is being injected varies, determine the maximum flow
rate, and use a proportionally fed chlorination system. |
| Chlorine Bleach (sodium
hypochlorite) |
| Household
bleach = 5 1/4% 52,500 PPM |
| Pool chlorine
= 12% or 120,000 PPM |
| Pool chlorine
dilutions: |
| Diluted 1 part chlorine to 9 parts water:
12,000 |
| Diluted 1 part chlorine to 18 parts
water: 6,000 |
| Note: use soft
or purified water when diluting chlorine bleach. |

per day of bleach you would use: |
