Results are for preliminary sizing; the final design is based on water analysis and a site survey.
Limits are 0.2 mg/L iron and 0.05 mg/L manganese. Stoichiometric oxidant demand is ~0.64 mg/L chlorine per mg/L iron and ~1.29 per mg/L manganese (KMnO₄: 0.94 and 1.92). Catalytic filters run at 8–12 m/h; manganese needs pH above 8.
Recommended systems
