Water Moving Aerator: How And Why It Works

There are two, 2 HP, regenerative blowers on top of the Lagoon Master; each is connected to a set of bubble forming diffuser grids.

The Phase 1 blower (1) feeds air to the course bubble diffuser grid (2) which produces large 1-­‐2 cm bubbles that rise quickly into a baffle (3), pushing water at a velocity capable of moving over 9 million gallons of water per day. This moving water stays on the surface un0l its weight forces it to drop down to the sludge.

The Phase 2 blower (4) feeds air to the industrial grade fine bubble diffuser grid (5) located forward of the coarse bubble diffusers. The fine bubbles are <1 mm in diameter, and are carried underwater for up to 35’ due to their inability to rise through the fast moving turbulence of the water above them. The 25’+ of residence 0me for the small bubbles at 1 atmosphere of pressure, provides 15 lbs of dissolved oxygen per hour into the water.
