Tube settlers / lamella clarifiers / plate settlers consist of a series of inclined plates or channels that provide a large effective surface area with a small footprint. As a result, basins with lamella plate separators are significantly smaller than conventional clarifier tanks. The additional surface area shortens the particle settling path along with its sedimentation time. Additionally, a plate inclination between 55° and 60° creates a balanced counterflow of sludge and water. In the end, this enhances the settling process.

One important factor for the selection of the right type of tube settler is structural loading requirements. Accumulated sludge in the tube settler channels can add up to loads of 20 lbs/ft3 or more so that collapse is a possibility. To avoid collapsing media, AET supplies reinforced tube settlers with superior product stability. During manufacturing, single-channel profiles are assembled to a media block through a tongue and groove system and heat welding. The resulting assembled blocks have high out-of-plane compression and shear properties comparable to a honeycomb structure. Therefore, AET tube settlers (in combination with the right support structure) are walkable for maintenance and cleaning purposes.

Another important factor in selecting the right type of lamella plate separator is the structural load ing. Through sludge accumulation loads of 20 lbs/ft3 along with the weight of the lamella plate separators, collapse is a possibility. To avoid collapsing media, AET supplies lamella plate separators with a higher material thickness than most products available on the market. During installation, single channel profiles are assembled to a media block through a tongue and groove system and heat welding. The resulting assembled blocks have high out-of-plane compression and shear properties similar to a honeycomb structure. One of the biggest benefits for the customer is that the offered lamella plate separators are walkable for maintenance reasons. Not only that, but they can be cleaned with a pressure washer if needed. Another big benefit is that the lamella plate separators are easily assembled on site.
