Operating Characteristics

  The DSA centrifugal submersible aerator is the most economical and most effective choice for sewage treatment processes which need extra air supplies. It dispenses with investment for engine rooms with the design of submersible motor, uses the star-like impeller, and the hybrid channel of radial air and water.

  Negative pressure is formed in the mixing chamber as the impeller rotates, which then inhales air. Stirred simultaneously by the water and the impeller, the negative pressure becomes bubbles through the diffusing channel and dissolves oxygen in the air into the water.
