gravity separation treatment

Wastewater treatment - Wikipedia

Solids like stones, excretes etc. and non-polar Impurities liquid's may be removed from wastewater by gravity when density differences are sufficient to overcome dispersion by turbulence.

Understanding Separation Essentials For Wastewater Treatment

May 15, 2015· Separation would be more easily attained between the solid and liquid phases if the solid-phase material and particulates were larger and heavier to allow gravity separation of the solid phase. As these particulates get smaller (and lighter) as colloids, significant separatory problems arise.
