SAFL Baffle
Stormwater Sediment
80%+ TSS Capture and Retention:


The Patentend SAFL Baffle removes sediment from stormwater, and the harmful chemicals (such as phosphorus) that cling to the surface area of sediment.

This is a low cost and zero maintenance device that helps engineers meet their stormwater TSS removal goals (Total Suspended Solids).

How it Works

The SAFL Baffle is a stormwater pretreatment system that fits into a sump structure (new or existing) and keeps sediment out of downstream water bodies and BMPs. It works by capturing and retaining sediment, by stopping the rotating scour action that takes place during high flow conditions.
