| Тойм: | In the aquaculture industry, the dissolved oxygen is one of the important
parameters that need to be monitored seriously. Aerator is normally used to increase the
level of dissolved oxygen in water. It functions to circulate or mixes the water top to
bottom to ensure that the oxygen content is uniform throughout the pond. It also exposes
the water surface to absorb oxygen from atmosphere. This aerator uses a new concept by
using flexible link to generate dissolved oxygen. The advantages that have in flexible
link were used as an actuator to generate and distribute dissolved oxygen in water. Three
type experiments were done to find out and verified the optimum parameter setting for
this aerator. The best result of dissolved oxygen level were found during run the flexible
link aerator at full power with 0.65m length of flexible link and immerses 25% in water.
As a result, the flexible link was successfully implemented as a new aerator concept
where it is able to generate oxygen up to 8.6mg/L with the average Standard Oxygen
Transfer Efficiency 1.84 kgO2/kWhr and suitable to used in the shallow pond. The key
success factor in developing this method is due to the characteristics that are available
on flexible link where it length can be extended to cover the surface of the water without
burdening the motor. More water surface area exposed to the atmosphere it will
encourage the absorption oxygen into water. |
