The process needs some modifications. If the iron concentration is high, above 1,000.00 ppm, a precipitation with alkaline solution is required, after filtration and removal of iron (iron hydroxide) and filtration of activated carbon. About pH, the same is being altered due to the disinfection process performed with chlorine, which is alkaline. The pH must be adjusted with acid solution. This is our suggestion, as it will be necessary to perform a pilot test in the laboratory, and then proceed to the practical execution in the treatment plant.
