Round the Lid, Not Through the Carbon

Tracer-Gas Capture Fractions of Passive Carbon Vent Filters at Gravity-Sewer Manholes

A research poster from the School of Underlying Conditions balances a constant-rate sulfur hexafluoride tracer through ten gravity-sewer manholes over six weeks and finds that passive carbon vent filters removing a median 98% of the hydrogen sulfide across their beds received a median 42% of each chamber's outflow, the remainder leaving around the lid, so that net control stood at 41%.
