Design an upflow solids contact basin for a softening plant treating groundwater. The plant has a maximum day design flow rate of 50,000 m³ /d and average winter demand of 25,000 m³/d. Verify that the design satisfactorily meets the GLUMRB guidance for flocculation and mixing period, detention time, upflow rate (overflow rate), and weir loading. Use Table 4-4 to select the upflow clarifier(s).
