A ballasted flocculation process has twohydrocyclones in operation (two trains) with aninfluent flow of 6,000 gpm and a microsand slurryrecirculation rate of 300 gpm. Six volumes of samplesfrom the train produced the following volumes ofsettled microsand: 20 mL, 15 mL, 15 mL, 30 mL, 20mL, and 20 mL. The six volumes of samples collectedin the cone averaged 2,000 mL. Calculate Cm, themicrosand concentration in th
