Seven aerdisc® Directional Aerators have been installed at Ashburton District Councils, Wilkins Road Wastewater Treatment Plant over the last three months. Three in the oxidation pond and four in the aeration basin.
Previously, the aeration basin had Qty 10 x 7.5kW incline-shaft aerators, each including a side-channel blower, for a total energy of over 80kW, but even so the plant continually suffered from low DO and major short-circuiting issues.
Upon installation of only four 7.5kW aerdisc® aerators with a total energy of only 30kW, the DO jumped and short-circuiting was eliminated.
