Are there economical options for removing iron& other metals from borewell water? Request low-cost solution for high volume water treatment requirements?
Hi Chandra, It depends what usage the water is destined for. we produce the way to keep iron in suspension for much longer and prevent oxidised scale build up on all pipes and surfaces in full time contact with treated water by use of just frequencies and pulses.
Depending on the quantity of iron, you have choices of Cascade Aeration, Tray Aeration or Forced Aeration. However the precipitate needs to be removed by clarification & Filtration or only filtration.
The Brumby Pump aerates the water right down in the bore. If you then pump to a tank and allow to settle for a couple of days, you should have crystal clear water...www.brumbypumps.com
Chandra Kant Tewari I would be able to provide you with a solution for this exact requirement. Please send me all relevant project details to my e-mail - gabe@imexconsultinggroup.com
Cooling towers convert ferous to ferric iron. Ferrous is water soluble and ferric is insoluble and settles down in cooling tower basins. This way major portions of iron can be removed. For further removal methods discussed by Alexander below can be explored.
Plenty of options. All depends on the chemical form of iron in the bore water. The easiest is to oxidize the dissolved iron with air or ozone and then separate the oxidized metal on sand or any other granular media. Ion exchange can be also used for that - may require sodium chloride for regeneration of the resin. In case iron is complexed with organics which is quite common, it would be beneficial to identify the optimal conditions of breaking down this complex to release iron and precipitating the released metal on media. Catalytic filtration using Birm, Filox, Manganese Greensand, FHM and Pyrolox and other media based on manganese dioxides has been proven to be effective. Hope this helps
