  • Comparing Gravimetric and Centrifugal Spin Data: Accuracy of Suspended Solids Results and Process Control Calculations

    ABSTRACT: The Carbondale Wastewater Treatment Facility is located on the banks of the Roaring Fork River at the intersection of Highway 82 and Highway 133 on Colorado’s western slope. Samples for total suspended solids (TSS) were analyzed by gravimetric analysis with 45 mm filter papers and by centrifugal spin for three years. While there is a clear correlationbetween centrifuge and ...

  • How & Why We Measure Suspended Solids

    In case you weren’t sure, Suspended Solids is simply a density measurement used to describe exactly how much waste sludge and particles are in the water, and is measured in milligrams per litre (mg/l), grams per litre (g/l) or percentage solid (%). 1000mg/l = 1g/l = 0.1%. It is used to calculate the amount of material, or load, in a wastewater or industrial system. Suspended Solids ...

  • Parallel evaporation after extraction of liquid dairy samples following the Mojonnier method (ISO 1211:2010) – gravimetric fat determination

    Parallel evaporation after extraction of milk samples with the Mojonnier The fat in liquid dairy samples is usually extracted with an organic solvent that is then evaporated to complete dryness prior to gravimetric analysis. In this short note, initial conditions and evaporation settings for the parallel evporation of milk fat dissolved in diethyl ether / light petroleum are presented. ...
