The ACU-LAM is a baffle system used in installations where there are difficult structural constraints such as where the inlet pipe enters the overflow structure parallel and adjacent to the weir. A standard static baffle would require placement at a certain distance from the weir. This would result in a portion of the influent to be directed to the downstream side of the baffle. As a result, all debris from this portion of the influent will flow over the weir. This problem is avoided by installing the ACU-LAM Lamella Baffle directly on the weir, requiring no additional space within the structure. The ACU-LAM Lamella Baffle consists of a series of vertically mounted, upward sloping, equally spaced, parallel stainless steel plates. The parallel plates are designed to maintain structural integrity for all flow conditions.
This unique design ensures that the overflow inlet slot is always submerged during an overflow event to ensure maximum floatables retention. As a result the debris is retained in the channel for removal by the dry weather flow after an overflow event. Its design also reduces the likelihood that sediments accumulated on the channel floor are stirred up and carried with the overflow.
