Design an upflow solids contact basin for a softening plant treating groundwater. The plant has a maximum day design flow rate of 10,000 m³/d and average winter demand of 5,000 m³/d. The primary softening clarifier is to be followed by a secondary clarifier that is to be used as settling tank for coagulation of the unsettled precipitate from the first tank. Verify that the design satisfactorily meets the GLUMRB guidance for side water depth, flocculation and mixing period, detention time, upflow rate (overflow rate), and weir loading. Use Table 4-4 to select the upflow clarifier(s).
