Abstract

This paper presents the result of experiment the flexible beam aerator model as a new concept to generate dissolved oxygen. This flexible beam method is inverted as compared to other researches done in this field. The vibration generated from the movement of the flexible beam will generate waves and bubbles in water thus generating dissolved oxygen. In this experiment, by using a optimum parameter setup, this new concept aerator able to generated dissolved oxygen up to 8.6 mg/L with the average Standard Oxygen Transfer Efficiency 1.84 kgO2/kWhr. The key factor in developing this method is by implement the characteristic of this flexible beam where it length can cover more surface water area. More water surface area expose to atmosphere it will encourage oxygen to absorb in water. The flexible beam movements circulate the water thus the dissolved oxygen can distribute from top to bottom. Three type experiments were done to find out the optimum parameter setting for this aerator. The best setting will give a higher dissolved oxygen level.
