How many types of settling are there in sedimentation tank?
Explanation: There are 4 types of settling in sedimentation tank, namely Flocculent, Discrete, Compression and Hindered settling.
In which type of settling, sedimentation of discrete particles takes place?
Explanation: In Discrete settling, sedimentation of discrete particles takes place where the particles have little tendency to flocculate.
The settling velocity of spherical particle is given by
Explanation: The settling velocity of spherical particle is given by stokes equation where vS = (g/18) * (G1) d^{2} /v when diameter d is less than 0.1mm.
In the expression vS = 1.8 (g*d (G1))^{ 1/2}, the diameter of spherical particle is
Explanation: The settling velocity of spherical particle is given by stokes law and when the diameter d of spherical particle is > 1mm, settling velocity is given by vS = 1.8 (g*d (G1)) ^{1/2}where G is the specific gravity of the particle.
In which type of settling, settling of particles takes place by the contact of impurities with each other present in wastewater?
Explanation: When large amounts of impurities is present in water, they contact each other in the compression zone and compression settling takes place.
