$3 we see that if the rate or liquid overllow, .. from the clarifier equals OQ., Eq. (5-36) becomes VX Q.(X.-X.) + Qx, + O'y, (6-2) By decreasing the sludge wastage rate, C.. the sludge age is increased. The sludge overflow concentration, X, may be eliminated from the above equa- tion by making a solids balance around the settler giving 8,- (6-3) 1 + R-RX + - Show transcribed image tex
