  • Anaerobic Biomass Activity Tests

    Anaerobic Biomass Activity Tests The methane production activity of anaerobic sludges is related to the history of the sludge, the biomass yield from the wastewater the sludge has been treating, the fraction of methanogens, and the presence of toxic substances. Best performance can be achieved from an anaerobic treatment plant if the operator measures the Specific Methanogenic Production (SMP) ...

  • Wastewater Monitoring Series, Part 1: Identifying the Gaps in Conventional Biomass Test Methods in Wastewater

    Biological wastewater treatment systems require living biomass to remove biodegradable contaminants from wastewater.  Effective treatment is directly dependent on the concentration of healthy biomass. It stands to reason that having an easy method to directly measure the quantity and quality of living biomass would be tremendously beneficial to the operation of biological wastewater ...

  • Effects of pH on chromate(VI) adsorption by Spirulina platensis biomass: batch tests and FT-IR studies

    Raw and methylated biomass of Spirulina platensis was employed in chromate batch adsorption tests at pH range 1–7. The acid conditions seemed to favour the removal of chromium (Cr) with a yield of 87.0 and 97.6% by using raw and methylated biomass, respectively. However, the chromate and total chromium determination, carried out in the same sample, evidenced that a fraction of ...

    This workshop was convened by the European Commission's Joint Research Centre, Institute of Energy Studies at Ispra, Italy, in co-operation with CONCAWE and EUCAR, the co-authors of the joint European well-to-wheels study [A3]. The second edition of the well-to-wheels study was released in May 2006 and is available on the JRC web site. This contains detailed evaluations of energy and GHG ...


  • Algae biomass cultivation in nitrogen rich biogas digestate

    Because microalgae are known for quick biomass growth and nutrient uptake, there has been much interest in their use in research on wastewater treatment methods. While many studies have concentrated on the algal treatment of wastewaters with low to medium ammonium concentrations, there are several liquid waste streams with high ammonium concentrations that microalgae could potentially treat. ...

  • Growth of microalgal biomass on supernatant from biosolid dewatering

    The paper reports the results of an experiment to assess the feasibility of including a photobioreactor within the design of a wastewater treatment plant, growing microalgae on the centrate from anaerobic sludge dewatering. The growth of algal biomass would take advantage of the available nitrogen and provide a substrate for biogas production by anaerobic digestion. Tests were carried out by ...

  • 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 ...

  • Effect of phosphorus concentration on phosphorus removal and biomass

    Membrane bioreactor (MBR) process was employed to study the effect of biological phosphorus removal (bio-P removal) and P-content in treated sludge with increased phosphorus concentration present in the wastewater. Further, the following four test fractions of raw wastewaters was obtained having different P-concentrations viz., run 1: P-20 mg/L, run 2: P-40 mg/L, run 3: P-60 mg/L, run 4: P-80 ...

  • Energetic and exergetic performance evaluation of improved biomass cookstoves

    This paper deals with thermal and exergy efficiencies of single–pot and double–pot improved cookstoves. These cookstoves are essentially made of cement and bricks and have at least five years of useful life. The cookstoves were tested with Acacia nilotica wood. Thermal and exergy efficiencies of the single–pot improved cookstove were estimated at 20.36%, and 8.10%, respectively, whereas for the ...

  • The Standard For Total Biomass Measurement in Metalworking Fluids

    Metalworking fluids provide a warm and nutrient-rich environment for growth of bacteria and fungus.  Once microbial growth is established it can contribute to the breakdown of the metal working fluid emulsion and consequently its ability to lubricate metallic surfaces.  Microbes also lower the fluid's pH, leading to corrosion of tool parts and staining of wetted metal surfaces.  ...
