Underflow concentration
WebThe concentration of hydrofluosilicic acid may be raised by recirculation to 15 to 20% solution. This hydrofluosilicic acid solution may be used as raw material for the … Webheight H2, where concentration is C2 (C2 is determined by extending tangent and bisecting angle of intersection). The time tu can be determined as follows (Metcalf and Eddy, 2003): a. Construct a horizontal line at the depth ‘Hu’, that corresponds to the depth at which the solids are at the desired underflow concentration, ‘Cu’.
