Lamella Clarifiers

In conventional clarifiers particles with a higher gravity than waste water will settle down to the tank bottom over time. The closer the gravity of the particles is to the one of waste water as longer takes the settlement process and as larger the clarifiers have to be build. Lamella clarifiers are a very cost effective alternative to conventional clarifiers as they reduce the needed tank volume by 2 to 4 times. Lamella clarifiers consist of multiple channels that function as additional surface area to reduce the settling path of the particles in the waste water. AET provides consulting and lamella clarifier systems consisting of lamella clarifier plate settlers, support- and anti-floating structure, sludge removal and effluent launders.


Equidistant, Chevron shaped plate settlers

Plate settlers come in different designs to offer the customer the best compromise between added surface and minimum risk of clogging. Therefore different channel sizes and slopes can be manufactured. The equidistant, chevron – shaped channel design has been proven to be the best design to avoid sludge accumulation and to have a balanced sludge – water counterflow within the channels.
