  • Suitable for continuous or intermittent operation.
  • Additional option of non-return valve available.
  • The membrane provides high oxygen yields.
  • Enhances mixing between the gas and liquid phases
  • In contrast to a surface aerator which has an electric motor in the water, a diffused aerator has its motor on the shore. Because of this the motor can be easier to manage or repair.
  • These systems is made to operate continuously so maintenance on its accessories is too low whereas in surface aerators.
