Removal of iron and manganese from drinking water supply

WebThe presence of iron, copper, nickel, or cobalt catalyzes the rate of deterioration; therefore, piping systems should be plastic or other non-metallic material to prevent active corrosion of iron, copper or brass materials. In summary: The most stable hypochlorite solutions are those with low hypochlorite concentration, WebHypochlorous acid is a weak acid and dissociates to form a hydrogen ion and a hypochlorite ion. The concentration or distribution of each species at equilibrium depends on pH and temperature. Between pH 6.5 and 8.5, the dissociation reaction is incomplete, and both hypochlorous acid and hypochlorite ions are present. Webiron-reducing bacteria, slime, and sulfate-reducing bacteria. Chlorine destroys target organisms by oxidizing the cellular material of bacteria. Chlorine can be supplied in many forms and in liquid, solid, or gaseous phases.
