when an influent screen is clogging is that called screen blinding?

Yes — if an influent screen is clogging because material is blocking the openings, that is commonly called screen blinding.

In wastewater and screening contexts, people may also call it clogging or screen blockage ; “blinding” is the more technical term when the openings are becoming covered or packed with solids.

Quick distinction

• Screen blinding: the screen openings are getting blocked by solids, fibers, or sticky material.

• Screen clogging: a broader, everyday term for the same problem.

• Pegging: sometimes used when particles are lodged in the openings, especially with near-size particles.

For an influent screen, “blinding ” is a perfectly normal term to use if the screen is losing open area because solids are stuck in it.

TL;DR

Yes — clogging of an influent screen is often called screen blinding , though clogging and blockage are also commonly used.
