Description
High Oxygenation Efficiency Sewage Surface Disk Aerator with Robust Propulsion
Product Overview

As a key horizontal-axis surface aerator for oxidation ditches, the rotary disk aerator provides efficient oxygenation, robust propulsion, and prevents sludge settling, ensuring thorough mixing for biochemical processes. Key advantages include deep working depths, high power and oxygenation efficiency, excellent corrosion resistance, long lifespan, flexible assembly, and low operating and maintenance costs.

Working Principle

Comprising a drive unit, flexible coupling, main shaft, disks, and bearing housings, the aerator operates by rotating the disks via a motor and gear reducer. The spinning disks and their blind-hole structures create water curtains and entrain large volumes of air for thorough mixing and efficient oxygenation. Meanwhile, the rotation strongly propels the wastewater forward in the oxidation ditch, keeping the activated sludge perfectly suspended.

Product Features
  • Compact Layout: Small footprint for flexible process integration
  • Durable Material: Injection-molded FRPP disks offer high strength and outstanding corrosion resistance
  • Optimized Hydraulics: Specially designed disk protrusions maximize gas-liquid contact. Delivers >10% higher oxygenation capacity than domestic peers and excellent propulsion. Maximum working depth: ~5 meters
Structural Components
Drive Unit: Includes motor (single/dual/VFD) and gear reducer. The vertical configuration uses a spiral bevel-cylindrical reducer for a compact footprint and superior motor protection against water mist.
Flexible Coupling: Available in flexible pin or rubber contact types; designed to absorb vibration and compensate for angular misalignment.
Main Shaft: Built from heavy-wall seamless steel pipe with FRP thermoset molding or heavy-duty anti-corrosion spray (Zinc/SS). It is lightweight, high-strength, and durable.
Aerator Disks: Injection-molded from high-strength FRPP. The disk surface integrates four functional structures:
  • Teeth: Provide propulsion for water flow
  • Water-splashing Lobes: Maximize air-water contact and oxygen saturation
  • Oxygen-storage Grooves: Entrain and shear air bubbles for deep emulsification
  • Centrifugal Channels: Eject "dead water" via centrifugal force for continuous oxidation

Expandable Capacity: Feature a split-type (two-half) design with a locking device for easy on-site installation and capacity expansion.

Bearing Housing: Supports total operational load while compensating for the shaft's thermal expansion and contraction.High Oxygenation Efficiency Rotary Disk Aerator with Robust Propulsion and FRPP Disks for Sewage Treatment
