Drinking Water Chlorine Disinfectant System
Drinking Water Chlorine Disinfectant System
(OP)
I need help in setting up a drinking water disinfection system for the company that I work with. This is new to me and I do not know where to start. The population served is around 25-35 people with a low to moderate water well flowrate. This will help us meet TCEQ regulations.

I need to have residual chlorine at .2mg/l and over a four sample average between .2 - 4. mg/l residual chlorine. I've been told that I can use gas, tablets or liquid bleach. I just need the simplest configuration to dose chlorine in the water line going into my two small storage tanks. Thanks in advance for your help.

Looking at the chart, a meter can be found giving 1 contact per gallon or per 10 gallons. If this contact is used to pace a dosing pump, varying flow rates from the source can be tolerated.
These pumps can provide 1 stroke for every pulse or 1 stroke for every 64 pulses or anything in between. Calculate the volume per stroke by dividing FEED/HOUR by strokes/min and then by 60 (min to hour):

The last thing is to specify a "de-gassing head". This will return a VERY small bit of flow to the supply tank at each stroke. Because the discharge is at the top, any gas will collect there and be returned to the supply tank. This will prevent gas from building up and causing pumping problems.
You will need to double check my numbers, but 0.01 ml/Gallon (of 12% sodium hypochlorite) will result in 0.3 mg/L chlorine residual, maybe?

You'll also need a way to constantly monitor chlorine levels. Something like this Hach unit:
