Primary Treatment of Wastewater
Framing: the primary treatments. The objective of so-called primary wastewater treatments is to remove the "coarser" component of the effluent: sands, oils and grease, a substantial portion of larger suspended solids. This is usually a non-self-contained stage of treatment, which in fact should reduce the pollutant load and facilitate subsequent interventions.
