The concentration of dissolved oxygen (DO) strongly influences the performance of aerobic biofilm reactors because organic oxidation is limited by the availability of oxygen. However, it is not necessary to maintain a high DO level in the reactors in order to overcome this limitation. Excessive aera

A simple flow-injection method for the automatic photometric determination of low concentrations of dissolved oxygen in waters was developed. The method uses Methylene Blue immobilized on a cationic exchange resin packed into a flow-cell located in the spectrophotometer, where the leuco form of the
