Benefits

  • High Fine-Solids Capture Efficiency

    The alternating stair-step lamella design forms a screenings mat that captures particles finer than the screen opening. This mat enhances fine-solids removal while allowing screening to continue.

  • Compact, Retrofit-Friendly Design

    The ESR can be installed in new or existing facilities without requiring channel modifications. Its compact inclined configuration and above-channel drive system make it well suited for retrofit applications.

  • Reduced Overhead Clearance

    A maximum setting angle of 57 degrees helps limit the screen’s overall height. This compact profile allows the ESR to fit facilities with restricted overhead space.

  • Reliable Self-Cleaning Operation

    Automatic, self-cleaning operation continually removes accumulated screenings from the lamella surface. This helps maintain consistent screening performance without interrupting operation.

  • Reduced Downstream Loading

    Capturing fine particles early in the treatment process reduces the amount of material carried into downstream equipment. This supports more effective primary, secondary, and sludge treatment operations.

  • Minimal Operator Intervention

    Automatic, continuous operation reduces the need for manual cleaning and frequent operating adjustments. The self-cleaning design allows the ESR to maintain performance with limited routine attention.

ESR: Hassle-free Sludge Screening

The ESR Stair Screen is an automatic, self-cleaning fine screen designed for primary, secondary, and sludge screening in municipal and industrial systems. Its alternating stair-step lamella design forms a screenings mat that captures particles finer than the screen opening while maintaining continuous operation. The ESR supports a range of applications, including municipal sewage treatment, slaughterhouses, tanneries, breweries, and paper plants. Its inclined configuration, with a maximum setting angle of 57 degrees, provides a compact footprint and minimizes overhead clearance requirements. Designed for new and existing facilities, the above-channel drive system supports straightforward installation without requiring channel modifications.
