What Is a Wastewater Bar Screen? Franklin Miller Inc

Wastewater Bar Screen. A bar screen is a filter that removes big solid objects from the wastewater. It’s a type of coarse screen that takes out rags, plastics, papers, metals, etc. from any flowing water. As the name implies, it usually consists of vertical steel bars spaced 1 to 3 inches apart. It’s usually the first step in a wastewater

The 3 Stages of Wastewater Treatment

Wastewater Sludge Treatment. The by-product of Wastewater or Sewage Treatment is called Bio-Solids.These are the Solids that are removed in the primary treatment and secondary systems. Sewage sludge, semisolid, or slurry residual material that is produced as a by-product of the wastewater treatment processes, still needs more treatment and is considered volatile.
