The ACU-LAM louvered deflector system is designed to prevent floating debris from entering stormwater overflow systems, combined sewer overflow (CSO) systems, sanitary sewer overflow (SSO) systems, holding tank overflows and pond overflows. The ACU-LAM is ideal for installations where structural constraints prevent the installation of an ACU-SELF self-adjusting floating deflector or an ACU-STAT fixed deflector.

Features

Application scope

The ACU-LAM louvered deflector may vary from model GAL-B-30-* to GAL-B-90-*. The GAL-B-30-* is designed for a flow depth of 12 inches (30 cm) and measures 24 inches (60 cm) to a maximum length of 6 feet (2 m). GAL-B-90-* is designed for a flow depth of 36 inches (90 cm) and measures 24 inches (60 cm) up to a maximum length of 6 feet (2 m). ACU-LAM model selection is based solely on flow depth and weir length. Units are currently marked with an asterisk due to the wide variety of model options.

How it works

The ACU-LAM is a drainage 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 deflector would need to be placed at some distance from the weir. This would result in part of the influent being directed towards the downstream side of the deflector. As a result, all debris from this part of the influent would flow over the weir. This problem is avoided by installing the ACU-LAM lamella deflector directly on the weir, requiring no additional space within the structure. The ACU-LAM lamella deflector consists of a series of vertically-mounted, upward-sloping, equally-spaced, parallel stainless steel plates. The parallel plates are designed to maintain structural integrity under all flow conditions.

This unique design ensures that the overflow inlet slot is always submerged during an overflow event to guarantee maximum retention of floating elements. As a result, debris is retained in the channel for removal by the flow in dry weather after an overflow event. Its design also reduces the likelihood of sediment accumulated at the bottom of the channel being stirred up and carried away by the overflow.
