Question

1) What do you understand by flocculation of particles?What type of filter helps in flocculation?
2) Give reasons why we should prefer using Biological water filters rather than chemicals?

3). Why it is necessary to measure pH during the process of filtration ofwater? ​

Answer 1

Flocculation, in the field of chemistry, is a process in which colloids come out of suspension in the form of floc or flake, either spontaneously or due to the addition of a clarifying agent. The action differs from precipitation in that, prior to flocculation, colloids are merely suspended in a liquid and not actually dissolved in a solution. In the flocculated system, there is no formation of a cake, since all the flocs are in the suspension...
