Well, when we think of Secondary clarifier, it is always the Conventional clarifiers and the reason being the MLSS volume and The conventional clarifier are to be designed based on the solids loading rate, and solids needs plan area, it cannot be replaced with tubes/plates. Hence its always the conventional clarifiers, further, if we provide Lamella clarifier then we need to realize that there would be a greater upward thrust because of the biomass and the MLSS and plates/tubes get easily lifted up, and hence poor clarifications. Lamella can be used when we are treating phosphorous chemically, as a tretiary clarifier as the phosphorous loading will always be on the lower side and Lamella can still maintain the same.
