Ask The Expert Question 2, July 2008
I am in Honduras, Central America. I need information on water treatment options for iron. I have a film of red color on the surface of a water well and the sanitary tank has turned red because of the water. We chlorinate the well but iron problems continue. We also add bensalconium chloride (alkyl dimethyl benzil ammonium chloride) in solution and use an aeration pump. I want to try to find a greensand type of filter or an ozone filter that will resolve this problem. Please let me know what is the best option.
