Effect of Barriers Height at Inclined Cascade Aerator

Abstract

World generate a large amount of water loss due development of carbon dioxide, hydrogen sulphide, methane and various volatile organic compounds responsible for bad taste and odour water causes the large amount of marine animals’ death. Aeration is used to increase to oxygen content of the water. Stepped cascade is one of that aerators one of that aeration which is applied. In this present study were analysed the performance of the Standard oxygen transfer rate (SOTR) and Standard oxygen efficiency (SAE) in water. In each case comparison of the performance of the SOTR at the barrier height 10cm shows different from the barrier height at 6cm. Same as comparison of the performance of the SAE at the barrier height 10cm shows different from the barrier height at 6cm. By varying the cascade height 0.5, 1, 1.5, 2 m and 0, 1, 3, 7 number of barriers at two different barrier height 10cm, 6cm. Found that performance increase with the increase in no of barriers, with the height of barriers and the height of cascade.
