Grit Removal Essentials

By Frank Weis, P.E., Senior Engineering Consultant, Smith & Loveless Inc.

More companies offer mechanized grit removal systems and services than ever before, underscoring the increasing grit removal focus in the industry. The rising application of membrane bioreactors (MBRs), specialized pumping equipment, and fine bubble diffusers in wastewater treatment plant infrastructure require protective equipment up front to maximize service life and operation. A properly designed and operated grit removal system prevents grit buildup in unit processes, scouring and plugging in lines, and fouling of diffusers and membranes. In times when funding sources are tighter and dollars are scarcer, protecting plant infrastructure proves critical. As the stakes increase, it’s wise to take a closer look at the dynamics of grit removal to achieve optimal outcomes.
