An unidentified presenter described how wastewater leaves the oxidation ditch by gravity and enters clarifiers where microorganisms finish breaking down organic material. "So after the oxidation ditch, it, gravity feeds over here into our clarifiers," the presenter said, explaining that the next step is to let solids settle so clear water can overflow the top.
The presenter emphasized the clarifiers’ role in separating settled biomass from clear water and returning that biomass to the oxidation ditch for additional digestion. "And if we're doing our job right, we got a 14 foot deep clarifier with nice clean clear water on the top," the presenter said.
The speaker also provided rough capacity and process details, saying the clarifiers are "half 1000000 gallons a piece" and that there are two clarifiers. The presenter added that the plant runs two separate processes that remain separate until aerobic digestion, after which flows are combined: "We run 2 separate processes. Everything stays separate until aerobic digestion. Then we then we do combine." These numbers and phrasing were given verbally and were not accompanied by formal documentation in the transcript.
No formal actions, votes, or policy decisions were recorded in the available transcript. The remarks appear to be an informational explanation or tour of treatment processes; the presentation concluded with an attendee-style reaction: "This is so cool."
