WebThe initial total solids concentration in a benthic segment [mg/L, or g/m3] is used to set the reference bulk density [g/mL] and porosity [L w /L]. As described in Section 8, the solids mass balance preserves reference bulk densities and porosities for benthic segments as individual solids are added or removed. Initial concentrations are specified http://www.abccert.org/pdf_docs/abcwwtfctable.pdf WebThe solids are then separated from the wastewater in the settling tank.
