  • Experimental study of pollutant washoff on a full-scale street section physical model

    This study analyses the mobilization of total suspended solids (TSS) for different spatial distributions of sediment load located over the roadway surface of a full-scale street section physical model. At the sewer network outlet, flow discharges were measured and TSS pollutographs were determined with manual grab samples and inferred from turbidity records. In all the tests, the rain duration ...

  • Rethinking micropollutant removal assessment methods for wastewater treatment plants – how to get more robust data?

    This paper covers the pitfalls, recommendations and a new methodology for assessing micropollutant removal efficiencies in wastewater treatment plants. The proposed calculation rules take into account the limit of quantification and the analytical and sampling uncertainty of measured concentrations. We identified six cases for which a removal efficiency value is reliable and four other cases ...

  • 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 ...

  • Destabilization dynamics of clay and acid-free polymers of ferric and magnesium salts in AMD without pH adjustment

    The physicochemical treatment was employed to treat acid mine drainage (AMD) in the removal of turbid materials using clay only (exp A) and a combination of clay, FeCl3 and Mg(OH)2 (exp B) to form a polymer. A 5 g sample of clay (bentonite) was added to 1.2 L of AMD and treated in a jar test at 250 rpm for 2 min and reduced to 100 rpm for 10 min. A 200 mL sub-sample from the 1.2 L mother ...

  • Characterizing shallow secondary clarifier performance where conventional flux theory over-estimates allowable solids loading rate

    The performance characteristics of relatively shallow (3.3 and 3.7 m sidewater depth in 30.5 m diameter) activated sludge secondary clarifiers were extensively evaluated during a 2-year testing program at the City of Akron Water Reclamation Facility (WRF), Ohio, USA. Testing included hydraulic and solids loading stress tests, and measurement of sludge characteristics (zone settling velocity ...

  • Travels with Paul – Quarries and Wastewater Treatment Works

    We followed Paul’s visits in February so we could show you just what a Partech sales engineer does! The month started off in Romsey where Paul carried out a site survey at a very muddy quarry… Paul went to see if Partech could help with their flocculent dosing control. The Partech team are pretty certain they’ll be able to offer an excellent solution, but Paul went to lend a ...

  • Influence of temperature on the activity of anammox granular biomass

    The aim of this study was to determine a short-term and long-term effect of temperature on the anammox rate and determination of temperature coefficients in the Arrhenius and Ratkowsky equations. The short-term effects of temperature on the anammox granular biomass were investigated in batch tests at ten different temperatures in the range of 10–55 °C. The maximum overall nitrogen removal rate ...

  • Case Study: Liz Bagshaw on the IRC sensors

    Our infrared IR’C sensors have been making waves in the world of glacial meltwater monitoring. Glacial environments are key indicators of global warming and climate change. They’re also home to a diverse range of microorganisms. Both of these need to be quantified and monitored, but doing this isn’t easy because of the cold, remote environments in which they are found. To combat ...
