Grande - Model ACU-BEND - Bending Weir System - Brochure

The ACU-BEND flexible weir system is designed to maintain maximum water levels upstream of the weir, allowing full utilization of all available upstream storage volume, without affecting overflow weir capacity in combined sewer overflow (CSO) applications. ACU-BEND`s unique, patented and extensively tested design works by only allowing any excess water in the system to reach the receiving watercourse, but only once the design upstream water level has been reached. This increases the storage volume of tanks and sewers and reduces the frequency and volume of overflows, resulting in less water pollution. This enables the ACU-BEND to overcome the disadvantages inherent in fixed weirs. The ACU-BEND can also create a hermetic seal that protects against backflow and controls odours, as it is normally in the closed position.
