The adsorption column mounted on top of the existing well-head hand pump as shown in Figure 1 is essentially a cylindrical stainless steel (SS-304) tank containing two compartments,namely Fe(II) oxidation and adsorption.Each gravity-flow unit is designed for a flow rate of 12–15 L per minute after backwash. Regeneration is carried out in several consecutive steps in the central regeneration facility in a single rotating stainless steel batch reactor. Table 1 provides the salient steps of the regeneration process.
