The ACU-SCREEN fine-slotted overflow screen system is designed to remove debris from stormwater overflow systems, combined sewer overflow (CSO) systems and sanitary sewer overflow (SSO) systems. The ACU-SCREEN fine-slotted screen offers an economical and effective solution for protection against floating and suspended matter entering receiving streams. The ACU-SCREEN fine-slotted screen is designed for installation on stormwater weirs, decanter weirs, CSO weirs and flood discharge weirs. The ACU-SCREEN`s modular design makes it suitable for any type of overflow system, and is easy to install in existing structures.

The Pump Action Screen (PAS) is a simple, robust mechanical CSO screen consisting of a stainless steel half-round steel basket with 6 mm perforations, submersible pump, distribution piping and venturi. It is designed to prevent the discharge of non-biodegradable solid debris larger than 6 mm in two directions.Screening debris is cleaned from the underside of the screen chamber and expelled past the end of the screen, eliminating any potential residues.

The ACU-TIP tipping bucket is a sediment flushing system designed to remove debris deposited at the bottom of tanks, such as stormwater retention tanks or CSOs and sanitary equalization tanks. The system works by releasing a torrent of fresh water stored in the tipping bucket. The resulting flushing wave progresses along the entirety of the drainage channel, pushing the debris deposited in front of it. The re-suspended debris are then transported by the flushing water to the treatment plant for disposal.

The ACU-GATE Flush Valve System is designed for efficient sediment removal from stormwater retention tanks, combined sewer overflow (CSO) retention tanks, sanitary sewer overflow (SSO) tanks, reservoirs, and tank bottoms. This system effectively removes debris in a single flush and has been successfully applied in CSO and SSO settings. Additionally, it can be utilized in agricultural and industrial applications to clean various batch tanks, ponds, and other similar structures.

The ACU-DRUM rotating drum system is a sediment flushing device designed to remove debris deposited in stormwater holding tanks, combined sewer overflow (CSO) holding tanks, sanitary sewer overflow (SSO) equalization tanks and tank bottoms, using a single flush. It has been used in CSO and SSO applications and can be used in agricultural and industrial applications to clean any reservoir, tank or batch-processing tank.

The ACU-VAC vacuum flushing system is designed for flushing rainwater, surface water, combined sewage/rainwater, raw sewage storage tanks and equalization basins. ACU-VAC can be used in circular storm tanks (up to 65 m in diameter), rectangular storm tanks (up to 150 m in length) and sewer systems (up to 250 m in length). The ACU-VAC is designed to have a tank bottom slope of between 0.5 and 2%. Circular tanks with a diameter of 165 ft (50 m) or more can use the ACU-VAC vacuum flushing system.

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.

The ACU-SELF self-adjusting floating 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-SELF can also be installed in canals or culverts where retention of floating elements is required.

The ACU-STAT fixed 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.
