Question

In WWTP, ______ remove solid materials.​

Answer 1

Answer:

sedimentation is an effective process

there are two new methods that efficiently remove solids at a high rate. One of these is Chemically Enhanced Primary Treatment (CEPT) and the other is mechanical separation. The CEPT process adds metal salts and polymers prior to the wastewater entering the primary tanks.

Answer 2

Solids such as stones, grit, and sand may be removed from wastewater by gravity when density differences are sufficient to overcome dispersion by turbulence.
