LJ-DSB600 Vertical Inverted Umbrella Surface Aerator with High Oxygen Transfer and Radial Flow Induction for Compact Wastewater Treatment

The Lanjiang LJ-DSB600 is a compact entry-level inverted umbrella surface aerator in the LJ-DSB series, specifically designed for small to medium oxidation ditches, activated sludge processes, and aerated lagoons.

The inverted umbrella impeller rotates at low speed, lifting oxygen-deficient water and sludge from below along the conical surface. The discharged water creates a hydraulic jump at the surface that entrains atmospheric oxygen, while simultaneously driving the mixture into a spiral circulation pattern at a velocity exceeding 0.3 m/s.

• Vertical shaft design with dedicated gearbox and compact footprint
• Eliminates horizontal oil seals to prevent gearbox oil leakage
• Main shaft machined from single-piece high-strength 45# solid steel
• Superior concentricity and durability
• Adjustable base with heavy-gauge steel construction
• Precision-machined levelling with ≥300 mm concrete anchoring

Ideal for smaller wastewater treatment facilities requiring efficient low-speed surface aeration in oxidation ditches, activated sludge processes, and aerated lagoons.
