Lagoon aeration

Aerated Lagoons are a simple way to biologically treat both municipal and industrial wastewater.

 

Mapal’s patented floating aeration units enable us to offer highly effective Fine Bubble aeration in lagoons; the aeration units float above the surface of the lagoonand the  Fine Bubble diffusers float 30 cm above  the lagoon floor, therefore, the floor does not need to be levelled, and there is no damage to geotechnical liningUsing Fine Bubble diffusersprovides high efficiency aeration, with high amount of oxygen per kW as compared to surface aerators.

 

Mapal has extensive experience in installation of its aeration units in live lagoonsInstallation is conducted with a crane, thereforethe lagoon does not need to be emptied  and workerare not required to enter the water during installation


Mapal’s units can supply a full aeration solutionor can work alongside existing surface aerationwhen supplemental oxygen is needed. This is done by harnessing the units in placethereforethere is no danger of them colliding with existing aerators.

Mapal offers Fine Bubble aeration for lagoons on a permanent or rental basis, as per the customer’s needs.
