1. For a municipal WWTP with an average daily flow of 2.0 MGD and a peak flow of 6.0 MGD, design a rectangular primary clarifier based on the following criteria: BODs concentration entering the primary clarifier 180 mg/L Assume minimal removal of BODs in the primary clarifier Use minimum depth (8 ft) criteria for a primary clarifier Multiple units capable of independent operation shall be provided in all facilities where design flows exceed 250,000 gpd. SOR = 1000 gpd/ft2 (normal conditions) SOR = 2500 gpd/ft? (peak conditions) Weir loading rate = 20,000 gpd/ft Maximum HRT = 2.5 hours What percent removals under normal conditions would you expect from your design based on the graph on page 346 of your textbook?
