5.2 design loading 5.2.1 primary clarifiers primary clarifier designs are primarily based upon surface overflow rate. In rectangular clarifiers length/width ratio is between 1.5 and 7.5 (usually 3). Normally, weir overflow rates of 10,000 to 20,000 gpd/ft 2 are used in the design of a settling tank. These spreadsheets also make weir overflow calculations to aid in effluent weir design..
