What are the Advantages of Aerated Lagoons

There are many ways to treat wastewater. Design constraints, wastewater parameters (organic load, BOD, COD, pH, temperature), land availability and value, CapEx, and energy efficiency, will all be considered, and eventually determine, which option is chosen.

One possible option to be considered is a wastewater aeration lagoon. This is a good option in rural areas, for a plant with a relatively low wastewater flow rate of municipal and industrial influent, where land is available, and population is sparse. A wastewater lagoon system does not require operations personnel to be always onsite, enabling one worker to operate several facilities simultaneously; it is considered to provide a very reliable process that is not very susceptible to changes in organic load, in contrast to activated sludge reactors; and has relatively low-cost operational expenses, therefore, it is becoming very popular throughout the world.

As lagoons do not have a levelled floor, the common way to aerate them is with surface aerators. Although surface aerators are relatively easy to install, when it comes to frequent breakdowns and maintenance, they are also known as an operator’s nightmare, not to mention high power consumption and low aeration efficiency.

Mapal Aeration Solutions offer floating fine bubble diffusers that provide bottom to top aeration and mixing for lagoons. Mapal’s system avoids all the problematic aspects of surface aerators – higher efficiency aeration, with better mixing, at significantly lower costs. Installation is conducted in a full lagoon, with the use of a crane. And to top it all, the robust stainless-steel structure of Mapal’s aeration units ensures that lifting the units out of the wastewater for maintenance is safe and easy. There is no need to enter the wastewater at any stage during installation or during maintenance – a tremendous H&S benefit. The units can be moved, removed, and re-used, saving in the waste and expense of manufacturing new units, providing considerable cost and environmental advantages.
