The principal phase involves separating solids from liquids. The sewage is pumped into sedimentation tanks, wherever gravity forces solids to the bottom of your tank. The water is then released, leaving behind a here sludge/slurry.
Grit chambers are extensive slender tanks which might be built to slow down the movement so that solids like sand, espresso grounds, and eggshells will settle out from the water.
