One cubic foot of water contains 7.48052 gallons. There are 1728 cubic inches in one cubic foot. The number of gallons of water in a cubic inch is 7.48052 gallons divided by 1728 cubic inches, which equals 0.004329005 gallons per cubic inch of water. There are 6,272,640 cubic inches of water on one acre.
Automatic Iron Filter Systems. Our main recommendations for iron treatment is the long-lasting Pro-OX Iron Filtration or the Pro-OX-AIR if odor is present. For water very high in iron with high levels of hydrogen sulfide and/or manganese, we recommend a pre-chlorination feed for maximum removal rates..
Iron bacteria in water can rapidly foul softener beds, and worse, can grow and pass through the beds in slugs. When such materials are found in the water, softeners should not be applied. Technically, industrial water softeners can remove dissolved ferrous iron by ion exchange, just as they remove calcium and magnesium.Further, precipitated iron can be removed by filtration. Problems arise, however, in getting the iron out of the softener bed during regeneration.deally, ferrous iron removed by ion exchange should be discharged with the hardness during the usual brine regeneration. In practice, however, it is usual for at least some of this iron to be converted to the ferric, insoluble state by oxygen in the regeneration water or brine.
