Consider a suspension that contains virus particles with a diameter of 0.1 μm and a number concentration of 104/mL. Assume that the mixture is stirred in a beaker (G=10 s¹), the temperature is 25°C, and an optimal coagulant dose has been applied (a=1). a. Estimate the time required to halve the free virus concentration (i.e., those not attached to any other particles). b. If the suspension also contains bentonite particles with a diameter of 1 μm and a number concentration of 5×106/mL in addition to the viruses, what is the time required to halve the free virus concentration?
