These three solids tests can be related with Equation :TS = TSS +TDS
Total Solids. For regulatory and treatment purposes, total solids (TS) can first be classified as suspended or dissolved. Total solids, as defined by Standard Methods and EPA, is the material residue left in a vessel after evaporation of a sample and [....]
The most basic solids differentiation is between settleable and floatable solids. An additional important differentiation is between volatile and non-volatile solids. A chemical or biological solid can potentially be removed from a wastewater by conversion through biological or chemical activity or incineration if the solid is organic and volatile (burnable at around 550°C). A volatile [....]
For a completely biodegradable wastewater such as glucose, approximately ten percent of the original organics remain as non-biodegradable cellular residues after biological oxidation. Hence, the cellular residues are not measured by the BOD test. Therefore:
BODu = 0.9ThOD —1
where BODu = ultimate BOD
ThOD = theoretical oxygen demand For domestic sewage and some biodegradable industrial wastes, the relationship [....]
Water filtration is a physical process of separating suspended and colloidal particles from waste by passing the water through a granular material. The process of filtration involves straining, settling, and adsorption. As floc passes into the filter, the spaces between the filter grains become clogged, reducing this opening and increasing removal. Some material is removed merely because it settles on [....]
