WARNING: DO NOT USE WITH ACID WELL CLEANER. Dangerous when mixed.
DESCRIPTION

Chlor-Safe is designed as an alternative to popular chlorine disinfection and is effective without pH control.

• Safe and effective alternative to traditional chlorine
• Reducing congestion in the well system
• Reduces the need for pH control
• Easy to use
• Long shelf life
• NSF certified for potable water well use

HOW TO USE:

Chlor-Safe is mixed with potable water in a tank at the surface and the solution is placed in the well and agitated to disinfect the well casing, screen, and filter pack.

1. Determine the static volume and the amount of Chlor-Safe. (Consideration should be given to increasing
this volume by two to four times to allow the sufficient disinfectant solution to reach all areas of the well and borehole that can harbor coliform bacteria or other contaminating organisms.)
2. In a tank on the surface, add the amount of Chlor-Safe to water as estimated from the dosage guide.
3. Place the chlorine solution in the well, evenly washing down the upper levels of the well before you place the solution throughout the water column
4. Agitate or surge the mixture to ensure good coverage. Let the solution stand in the well for a minimum of 12 hours. Additional agitation before removal is beneficial.
5. Pump the solution to the surface, we recommend neutralizing using Chlor-Out NW-500, and discharge in accordance with local rules and regulations.

FAQ:.

Q: What is Chlor-Safe?
A: Chlor-Safe is an alternative to using traditional chlorine (bleach) for
disinfecting a well. It is a granular product that is dissolved in water and added
to the well.
Q: What can Chlor-Safe be used for?
A: Chlor-Safe is used to disinfect wells – removing things like coliform, iron
bacteria, E. coli, and bacteria that cause a rotten egg smell. It also will break
down bonds in residual drilling mud or clays to reduce congestion in the well.
Q: Can it be poured directly into the well?
A: No, Chlor-Safe should be added to a container/tank of water at the surface
before adding it to the well. This makes sure the chemistry is in solution before
putting it downhole – otherwise, it would be too concentrated at the top of the
well and too weak at the bottom, where most of the bacteria are.
Q: Is Chlor-Safe a copy of Sterilene?
A: Chlor-Safe is a similar product to Sterilene but has
been specifically designed to dissolve into solution faster and get to work
sooner to disinfect wells and remove bacteria. 
Q: Treatment Dosage is in pounds, how does that convert to cups?
A: 1 lb. = 1.6 cups (1 kg = 1200 ml)
