Accessible Language

• Nitrification is the two-step biological oxidation of ammonia-nitrogen to nitrite and nitrate using oxygen as a terminal electron acceptor.

• Some bacteria obtain energy from ammonia (NH3) or nitrite (NO2). This process is called nitrification.

Scenario Worksheets

• Real world operational problems.• Complex solutions with multiple steps.• Operator must draw conclusions from

chapter material and apply.

Sample Worksheet Scenario• A small activated sludge facility can only control

their wasting pump by manually turning it on and off. This means the operator must walk across the site each time they want to waste. The same operator also operates the water treatment plant and must frequently be away from the WRRF in the middle of the day. If they collect samples of the MLSS and RAS early in the morning, the laboratory can have results back by 2 pm each day. What can this operator do to make sure he wastes enough each day without overwasting?

Sample Worksheet Scenario• A ski resort has an activated sludge process. The

SRT is currently at 12 days and the MLSS concentration is 1800 mg/L. The resort has been open since September, but Christmas break is coming up in a few weeks, which is when they have the most visitors. The operator is concerned because the influent BOD5 load will increase when all of the visitors show up. They don’t think they have enough MLSS to maintain an F/M ratio of 0.2 kg BOD5/kg MLVSS•d (0.2 lb BOD5/lbMLVSS•d). The operator decides to decrease their wasting rate so they can build up their inventory before the new BOD5 arrives. Was this the right decision? Why or why not?
