Abstract
An improved method and apparatus for treating liquor containing biodegradable wastes wherein the liquor is first delivered to a quiescent settling zone and then to an aeration zone. The aeration liquor is delivered downwardly through a column of submerged fixed media having a high surface area to volume ratio so that aerobic microorganisms can grow on their surface. The liquor is recirculated through the aeration zone and fixed media, and is withdrawn from the unit after treatment.
