Solids which include stones, grit, and sand can be removed from wastewater by gravity when density dissimilarities are adequate to overcome dispersion by turbulence. This is usually accomplished utilizing a grit channel intended to make an the best possible movement price that permits grit to settle and other a lot less-dense solids for being carried ahead to the following treatment phase. Gravity separation of solids is the main treatment of sewage, wherever the device process is called "Principal settling tanks" or "Major sedimentation tanks".

The sludge is often a by-product or service of Most important treatment and will at times be repurposed as a fertiliser, however website it demands treatment like de-watering to stabilise it. Incineration will be the probably location for heavily contaminated sludge.
Many of the water is taken off in a very action named thickening then the sludge is processed in massive tanks termed digesters.
