Bar Screens — Headworks

The first line of defense — mechanically cleaned bar screens that keep rags, debris, and solids out of your treatment process.

What is a Bar Screen?

Bar screens are the first line of defense at a wastewater treatment plant, removing rags, plastics, sticks, and other large solids from incoming wastewater before they can damage pumps, clog pipes, or foul downstream equipment. Mechanically cleaned bar screens use rakes or reciprocating mechanisms to continuously remove captured debris and deposit it into a screenings handling system — keeping the channel clear around the clock without manual intervention.
