1450 – 2950rpm Fine Bubble Membrane Diffuser Centrifugal Aerator Fine Bubble Disc Diffuser

Centrifugal Aerator

Product Overview

The Centrifugal Aerator is a high-efficiency water aeration device designed to increase dissolved oxygen levels and improve water circulation. It is widely used in municipal and industrial wastewater treatment, aquaculture ponds, and lakes. The aerator employs a centrifugal impeller to draw water and air, mixing them efficiently for enhanced oxygen transfer and improved water quality.

Working Principle

• The motor drives the centrifugal impeller at high speed.

• Water is drawn into the impeller and mixed with air, producing a vortex and fine bubbles.

• Oxygen is transferred to water while creating circulation, enhancing biological treatment efficiency.

• Treated water is discharged into the tank or pond, ensuring uniform oxygen distribution.
