Lagoon Master Aerator

The Lagoon Master Aerator is ideally suited to provide aeration and mixing in shallow pond/lagoon wastewater treatment systems. The Lagoon Master Aerator has two (2) independently operating regenerative blowers, each feeding air to a bubble-forming diffuser grid. The 1st blower runs continuously feeding the rear most coarse bubble diffuser grid, which creates motive action resulting in horizontal and vertical mixing. The 2nd blower supplies air to fine-bubble diffusers that increases the dissolved oxygen in the water column, and through the motive mechanism created by the coarse bubbles, also provides an oxygenated plume that brings dissolved oxygen into the sludge layer at the bottom. These processes allow for gentle sludge turnover and continual sludge digestion.



The Lagoon Master Aerator is available in 2 versions: Version 1 (V1) has the blowers mounted on top of the unit, and Version 2 (V2) has the blowers mounted on the pond/lagoon embankment. The only maintenance required on the Lagoon Master Aerator involves cleaning the stainless steel air intake filter on each blower. These filters will last for years but occasional cleaning is required.

    • Aeration & mixing with low power input
    • Destratification of water column
    • Odour elimination
    • Reducing algal growth
    • Organic breakdown of settled sludge
    • Reduces/eliminates sludge build-up
    • Easy to install
    • Simple to operate
    • Low maintenance, no moving parts
    • Low power consumption


The Reliant Lagoon Master Water-Moving and Sludge Activating Aeration System is not a standard aerator; Lagoon Master systems continuously move water along the bottom of a lagoon or pond, delivering large amounts of dissolved oxygen (DO) very efficiently, using minimal energy. Compared to standard paddlewheel, vortex, static tube, hose diffusion, spray (fountain), or aspirating aerators, Lagoon Masters” is more efficient, less costly to operate, and requires less maintenance.
