De-ironing and de-manganisation with O2

Enhanced reaction by pure Oxygen


Many waterworks use pure Oxygen instead of compressed air because of its almost five-fold higher solubility in water then Oxygen from air(see figure). As a result DOC levels beyond 12 mg/l are easily achievable and provide a proper ambient for the reaction of Manganese. Even Ammonium may be reduced by means of pure Oxygen.


For the rapid and complete dissolution of O2, Messer supplies several widely tested technologies, varying from fine-bubble feed directly into the main water stream to complete dissolution in a side stream under hydraulically defined conditions. In a project we specify the feed method that fits the customer needs regarding local conditions best.
