Effective headworks screening is the foundation of reliable and cost-efficient wastewater treatment. Our presentation, Wastewater Screen Technologies and Design Considerations, provides a comprehensive and practical guide to selecting and designing screening systems that maximize protection of downstream processes, extend equipment life, and reduce long-term operating costs.
Drawing on data from the UK Water Industry Research’s internationally recognized National Screen Evaluation Facility, we will demonstrate how Screenings Capture Ratio (SCR) directly impacts plant performance and operational efficiency. Attendees will gain a clear understanding of the comparative effectiveness of screen types—including center flow, through flow, multi-rake, and step screens—and how SCR influences debris removal, maintenance demands, and sludge quality.
Beyond theory, the session emphasizes real-world application. We highlight design standards for screen velocities, explore velocity adjustment strategies, and share proven approaches to minimizing headloss and eliminating bypass. Attendees will see how advanced design features—such as stainless steel construction, non-submerged components, replaceable wear tracks, and fully enclosed housings—optimize safety, reliability, and odor control.
We will also address the full screening process by examining screenings handling systems, including washing, compacting, dewatering, and transport technologies, ensuring that participants leave with a complete understanding of both front-end screening and downstream solids management.
The presentation concludes with case examples across municipal and industrial applications—from membrane bioreactors (MBR) and combined sewer overflows (CSO) to septage receiving stations and industrial intakes—demonstrating the versatility of modern screen designs.
By blending technical rigor with practical insights, this session equips decision-makers, designers, and operators with the knowledge needed to select the right technology, ensure regulatory compliance, and deliver long-term operational savings.
