    「By applying this method, the number of oxygen-supply cycles required for aerobic treatment is reduced, and running costs such as equipment depreciation and labor costs required for oxygen supply are expected to decline by approximately 60% compared with the conventional method using aerobic treatment alone.」

    The Company developed combined aerobic and anaerobic treatment using nitrate and ferric ions as electron acceptors, demonstrated oil decomposition in medium-scale and outdoor tests, expects to reduce running costs by approximately 60%, and plans demonstration tests at actual contaminated sites.
