Solution for iron problem

Postby chem geek » Sun 17 Mar, 2013 20:08

I'm cross-linking this thread to this TFP thread where an experiment was done to remove metal stains using hydrogen peroxide and it appeared to work very well.

Before you go ahead implementing this method, you should first backwash the filter.
Calculate how much flocculent you should add. Usually, for every 6,500 gallons of water, it is suggested to add one quarter of a gallon of flocculent.
Then, add flocculent to the waters so that it mixes with the water to attach itself to the iron. Once it attaches to the iron, it pulls the iron to the bottom of the pool. This way, it collects on the floor of the pool.
Remove the collected metal on the floor. Since it settles on the floor, it would be very easy for you to remove it.

If using that method, you need to use the right flocculent. To flocc metals (positive charge) you need an anionic flocculent (negative charge) to pull the charged particles together.

To be honest that method is long winded and requires more chemicals. Sequestriants are short term as the chlorine is used up to break them down so using more chlorine, likewise with algaecides, but hey that's what built the pool industry!

Better to filter the iron out. A really good filtration media like Activate from Dryden Aqua has a negative surface charge so will attract iron. Simply reduce the iron in the pool with ascorbic acid from the staining version back into solution non staining. Then put a chlorine source into the skimmer to re oxidise it just before it enters the filter. The iron will plate out and be grabbed by the filter media and you'll need to frequently backwash the filter and repeat until the iron is depleted. You can measure the iron in the backwash water to prove it's working.

Hey I get that you guys know about this stuff in great detail but I don't have all this chemistry background. I have an above ground pool that holds 4800 gallons of water. What product can I buy to get the iron out of my pool? I appreciate your intelligence but I just need a specific straight answer if you could, please?
