Question

why filtration better than decantation for class 6​

Answer 1

ello dear!!

This is so because it can be used to separate even smaller solid particles, which may not completely settle down with sedimentation. At the same time, during decantation, there is a chance of the particles mixing back in the liquid. Filtration technique can be used to overcome this as well.

Answer 2

Because filter removes small impurities and sedimentation and decantation remove large solid impurities. So filteration is better
