In this system talking about separate particles in Wastewater, I used to use dictionary to translate but I don't get. Whom know about it please explain me.

Thank you

In this system, heavier grit particles settle to the bottom (of the channel), while lighter organic particles remain suspended and are transported out of the channel.
This is OK,although the part in brackets could be left out. "The lighter particles remain suspended" means that they are suspended in the water, they don't sink to the bottom.

Yes. Some further points:

It is taking about a system in which heavy pieces (heavier grit particles) go down and they continue to be in that place (settle).
Lighter particles don't go down- maybe because they are not heavy enough to be drawn by the force of gravitation.
So lighter particles remain somewhere in the middle of the container, and then they are removed (transported) from the system.

Why do you have to say that the particles
'remain suspended or are resuspended'?
