UF Wastewater Treatment Plant Tour

UF Water Reclamation Facility

http://bellsouthpwp.net/r/e/reginawilliams/index.html

Overview

• Treats wastewater generated from housing and dorm areas, as well as academic and auxiliary buildings on the main campus (3 mi2)

• Facility has been in operation since 1994 • Uses BioDenipho Process to treat

Grit Removal Conveyor

Vortex Grit Chamber Automatic Bar Screen, Screen Chute & Muffin

Monster (Channel Grinder)

Influent Flow & Influent Flow Meter

What is another way to measure flow at a wastewater treatment plant?

Channel Grinder Grind wood, plastics, rocks, nuts, bolts, wire, sludge and other foreign material that can cause damage to process and waste water equipment

Bar Screens • Required to remove objects greater than ½-1”

(e.g., paper, twigs, rags, plastics)

Mechanically Cleaned Bar Screen

Anaerobic Basins

Anaerobic Basins

• Activated sludge from the secondary clarifiers added in channel splitter box just before anaerobic basins

• Low-speed mixers provide a homogenous mixture of the activated sludge without the creation of any floc shear or vortices.

• As the influent and return activated sludge are stressed under anaerobic conditions, bacteria begin releasing phosphorus into the mixed liquor, increasing the phosphorus concentration

Aerobic/Anoxic Basins

Aerobic/Anoxic Basins

Anoxic Basins Oxidation Ditch

Nitrification: ammonia oxidized to nitrate

Microorganisms convert stored BOD (biochemical oxygen demand) to CO2, water, and increased cell mass.

Uptake phosphorous (necessary for cell growth) – net P uptake is more than that released in anaerobic basins

Denitrification: Reduce nitrate to N2 gas

Low dissolved oxygen concentration

BOD is degraded

Where does the effluent and WAS go?

Effluent water: Re-use – on-campus irrigation (90%)

Well

Overflow to Lake Alice

WAS: Sludge is dewatered first and then land applied
