Plant/Process Description:
The San Angelo Wastewater Treatment Plant is a Conventional Activated Sludge Treatment Plant that treats an average of 9 to 10 million gallons per day. The plant uses three Anaerobic Digesters for sludge stabilization. The treatment process consists of the following steps:

1. Lift Station: All of the wastewater from San Angelo flows into a wet well located at the wastewater treatment plant. The wet well contains large pumps that pump all the wastewater to the head works of the plant.

2. Mechanical Bar Screens: There are two mechanical bar screens located at the beginning of the head works. These bar screens are set on times to operate every 15 minutes. The bar screens have square tubing spaced approximately one inch apart. Any large rags or debris is stopped by these bar screens. The bar screens have large mechanical rakes that clean the debris off the bars and deposits them into a dumpster for disposal in the landfill.

3. Grit Removal: There is a grit removal system after the wastewater goes through the bar screens. Here sand, gravel, etc., are removed from the system and taken to the landfill for disposal.

4. Primary Clarifiers: There are four primary clarifiers that slow the flow of the water down to allow very fine particles to settle out. The sludge that settles to the bottom of the clarifiers is pumped to the digesters for stabilization. The effluent from the primary clarifiers flows into aeration basins for further treatment.

5. Aeration Basins: There are two aeration basins. Each basin contains over 3,000 ceramic fine bubble diffusers. The diffusers act just like an air stone in a fish tank. Air flows through the diffusers to provide oxygen for the aerobic bacteria in the aeration basins. The aerobic bacteria thrive in the presence of oxygen and feed on the organic matter in the water thus removing pollutants in the water.

6. Final Clarifiers: There are four final clarifiers that slow the flow of the water down to allow the sludge from the aeration basins to settle out. The sludge settles to the bottom of the final clarifiers where most of it is recirculated to the aeration basins to maintain an adequate level of aerobic bacteria. The cleaned wastewater flows into a wet well for pumping to the holding reservoirs. The water from the reservoirs is either pumped to the Tom Green County Water Control and Improvement District located in Veribest for irrigation or is irrigated at the city's farm.
