We have a groundwater well from which the water comes out of colorless and after exposure to air the water changes color to a yellowish red color, the water was examined and found to have a high percentage of iron. What is the best way to treat water to remove dissolved iron in water
Simple answer. Oxidise the dissolved iron to turn it into a precipitate then remove using an OVXF filter.

I would recommend process line consisting of spray aeration, retention, sand filtration and disinfection.

You can incorporate Cascade aeration system and then do to chlorination upstream to remove the Iron content in water. if the quantity is less and the flow rate is small then you can even go in for softening. There are specific iron chellting resins also

My friends thank you for the help, I ask God to bless you

Depending on how much water is removed from the well at any given time you may have enough residence time to simply aerate the well water otherwise you may need to pump it into a separate containment cell and aerate it.
It would be advised to conduct a thorough check as some have already mentioned, of the various elements in the water. You want to be sure that simple aeration will cure your issue. Don't hesitate to contact me regarding our toroidal vortex circulator aeration technology for ponds, tanks, and lakes and our well aerators.

There is another alternative - do nothing. Many thousands of people live with iron in their water - there is no health issues. You may just need to clean out small valves from time to time, and flush out storage tanks once per year or so. We lived with such a situation for about 30 years, in fact it was the best tasting water we ever had. (we have now moved to a new smallholding where the borehole water is quite hard - and we miss our old iron rich borehole.

My patent IN 201811011885 can help.and not just remove but you can use the iron elsewhere to manufacture something and earn.

Hi Mohammed, You could use BioZeo WATER a clinoptilolite zeolite filtration media to solve this problem.

Mohammed, once you get the iron and manganese levels in check, please check out a system called the Ketos Shield that does real time testing/monitoring and unmanned continuous water sampling of 23 water quality elements including iron, manganese, alkalinity and pH which are discussed below. https://ketos.co/

Iron removal can be achieved using aeration cascade, settlement lagoon or tank and then polish with reed bed/wetlands. Any groundwater rich in iron might also contain manganese and aluminium plus sulphate. It is therefore worth checking the alkalinity and acidity (as mg/l CaCO3) of the groundwater as low alkalinity (<300 mg/l) will often inhibit iron oxy-hydroxide floc formation. The aeration cascade is used to elevate dissolved oxygen content, but it also helps liberate any entrained carbon dioxide which might depress the pH. NB - Please note checking pH only gives a partial picture of the acid/alkali balance, alkalinity is the key parameter to buffer pH changes.

Can be used the Pyrolusite as the media for Iron and Mangnese adsorption. We have a million tons reserved so you can order as your requirement.

I agree with Park Winter , Joseph Cotruvo and Thomas Getz . The most effective method for iron removal is to convert soluble iron to insoluble by oxidation followed by filtration for solids removal. Oxidation can take place via oxygenation (aeration) wich needs long time and big aeration tank, or by addition of oxidating agent like chlorine (the cheapest one). The problem using oxidating agent (let's say chlorine) is that you have to take care how to remove the exess residual from the outlet water in order to follow the needed standards using an appropriate reductive agent. For the case of chlorine the cheapest is sulfites, like sodium metabisulfite.

And if you have iron, its also very likely you have manganese, worth testing for and compare levels with standards.

Check out these guys https://www.dmi65.com. We used this process at a bottling plant in New Zealand with great results. If using chlorine as the oxidising agent you will need carbon filters to remove. And the finished product was great!

You can use alum for allowing the turbidity to settle down at the bottom and then siphon the clear water from the top

An actually depended on heavy metal in that water such as iron , manganese level. And then selected of the oxidizing agent for oxidized such as Ozone Chlorine Aerator Manganese peroxide and then Sediment and/or clear and activated filter. However it also looking for your budgets too which this is a important things.

I agree with Mr. Joseph Cotruvo who advised "...Oxidation with air or chlorine followed by filtration to remove the ferric hydroxide precipitate is the cheapest and simplest approach..." He is correct. This is simple and cost effective. Best wishes.

Ozone injected into an atmospheric storage tank is an environmentally sound and fairly inexpensive alternative. Depending upon the pH or the water and other factors, there are also some medias that can be used that precipitate out the iron and then mechanically filter it. The best way to determine the options that make the most sense is to look at a water analysis. Then we can see what other issues there are with this water and make sure you are addressing all the problems that you want to address.
