Activated carbon treatment

Activated carbon treatment

Activated carbon treatment

(OP)
My water treatment plant has a leaking reservoir tank issue. It is leaking about 10 gallon/min of treated water with 1.70ppm chlorine concentration into the creek. I am buying GAC to treat the leaking water. How do I calculate the quantity of carbon I need or the contact time for carbon?

RE: Activated carbon treatment

You are probably better served with a VitaDChlor feeder:

If you still want to use carbon, you can get by with a simple residential GAC filter. GAC has an infinite capacity for carbon. It takes about 8 gpm/cu. ft. GAC with a minimum 2 feet deep bed.

Hi bimr,
Thank you for your input. I didn't understand the second part of your answer. I want to see the quantity of carbon I need to neutralize water with 1.7ppm chlorine level and flow rate 14400 gallon/day. I have been treating the water with the Na2SO3. I would like to see the price difference of this two method.

RE: Activated carbon treatment

Columns are designed on the basis of throughput. For 16 gallons per minute, you would need a column with 2 cu. ft of GAC with a minimum bed depth of 2 feet.
