In ecology, the term “resilience” refers to the ability of the environment to absorb disturbances without seeing its structure and functionality characteristics significantly altered, and to recover its original state once the disturbance is over.
Lamellar resilience is the ability of a lamella clarifier to continue working properly without significantly altering its performance in case of
excessive flow. Whether or not the lamella clarifier shows this characteristic depends on the design having taken the resilience into account or not. Usually, the design of a new lamella clarifier does not consider it for cost reasons. On the contrary, most existing clarifiers that are converted into lamella clarifiers show lamellar resilience, which means that they are able to handle excess flows that had not been contemplated in their initial design.
