A water treatment plant is processing water at a flow rate of 1.5 m/s using three parallel treatment trains. The detention times for the rapid mix tank, flocculation basin, and rectangular sedimentation basin are 10 sec, 30 min and 60 min, respectively. The velocity gradients for the rapid mix and flocculation tanks are 900 s and 60:40:20 s1, respectively. The viscosity of water is 0.001 Pa-s. (a) Determine the size and power requirements for rapid mix tanks. (b) Determine the...

your answer.
A settling tank is being designed to remove suspended particles through Type 1 settling. The density of the particle is 1045 kg/m23 and the density of the water is 1020 kg/m2. The diameter of the particles is 0.2 mm and the temperature is 25* C. Assuming laminar conditions, find the settling velocity, vi, for the particles. If the overflow rate is 65 m2/d m2, what is the percentage of...

You are hired to design a rectangular sedimentation tank (length to width ratio = 3:1 and detention time ~ 2 h) for a new water treatment plant (flow rate: 0.04 m/s; temperature: 20 ). Suspended particles can be removed when the overflow rate is higher than the settling velocities of particles. You have finished characterizing the influent particles (assuming all of them are spherical) and obtained the following results: Particle diameter (m) Particle density (kg/m) Percentile 50 1.4 x 10...
