Fine Bar Screens

Fine bar screens represent essential preliminary treatment equipment, removing smaller debris, plastics, and fibrous materials that pass through coarse screens but could damage pumps, clog pipes, or interfere with downstream biological and physical treatment processes. With bar spacing ranging from 3-10mm, these screens provide a critical defense layer protecting treatment assets.

Mechanical fine bar screens feature either step screens with ascending flights or chain-and-flight mechanisms that continuously remove captured screenings. Automatic operation ensures consistent performance without manual cleaning, while robust construction handles peak flows and shock loads. Stainless steel construction and corrosion-resistant components ensure long service life in aggressive wastewater environments.

Spans Envirotech supplies fine bar screens from leading manufacturers, engineered for reliability and low maintenance. Our screening solutions incorporate optimized hydraulics, automated washing systems, and integrated screenings handling to provide complete, turnkey screening stations that protect treatment infrastructure while minimizing operational costs.
