Tonka Water Iron Removal Technologies
The treatment options available for iron removal include combinations of aeration/detention/filtration, oxidation/filtration and for low levels (<0.5 mg/l) direct ion exchange.
Tonka Water’s approach to iron removal starts with a water analysis and definition of treatment goals. Typically, a multi-stage treatment process is the most cost-effective and will be easiest to control and operate. The first step is aeration, where iron oxidation is achieved, allowing the soluble iron to convert to an in-soluble form which can be filtered. Following aeration and adequate detention, our filtration solutions can be either gravity or pressure, in accordance with recommendations by 10 States Standards or the relevant approving authority. Depending on the levels of iron, detention with sedimentation can be provided as well.
Filter medias applicable to iron removal include a wide variety, from anthracite, dual media, or our highly efficient IMAR™, a unique media specially developed by Tonka Water to enhance removal while minimizing backwash waste.
Tonka Water offers pilot testing to optimize an existing plant or to assist in the design of a new plant.
