Screen CSO flows in a small footprint, maintaining high treatment efficiency even under surcharged and submerged conditions.

With the threat of a sewer overflow, you need a powerful and highly efficient screen that will keep flow moving while maintaining high treatment. The Heliscreen® is a compact, powered combined sewer overflow (CSO), sanitary sewer overflow (SSO) and wet weather screening system that delivers reliable screening and capture of gross solids and floatables, continuing to operate with high ef?ciency even under surcharged and submerged conditions.

Providing effective operation even under extreme flow conditions, the Heliscreen® can handle high concentrations of screenings down to 6 mm in diameter, retaining 100% of screenings on the sanitary side of the overflow weir and preventing the need for screenings handling.

Compact, self-cleaning and easy to install and maintain, the Heliscreen® is a versatile CSO, SSO or wet weather overflow solution that is ideal for small, constrained sites with little headloss.

Applications

  • New and retrofit CSO or SSO facilities
  • Sites constrained by hydraulic levels or chamber dimensions
  • Remote sites or facilities with low maintenance requirements


Versatile and adaptable, the Heliscreen® is available in standard diameter sizes of 300, 500, 700 and 1000mm. The versatility of the Heliscreen® allows for units to be installed in parallel or in series to accommodate any flow requirements.

The Heliscreen® has the advantage of retaining 100% of the screenings on the foul side, as well as the ability to work under surcharged conditions. It is self-cleansing, handles high concentrations of screenings and is easy to install and maintain.
