  • ATP Results vs. CFU Results - Consideration #1

    Culturing techniques have been used as the standard method to identify specific microbes of concern in public and environmental health sectors for over 100 years. While these tools excel in identifying specific microorganisms, they have their limitations, particularly the speed of results (from 1 to 28 days or longer, depending on the species present) and the inability to quantify the total ...

  • Activated sludge optimization using ATP in pulp and paper industry

    The activated sludge process is an old technology, but still the most commonly used one for treatment of wastewater. Despite the wide spread usage the technology still suffers from instability (Tandoi et al. 2006) and high operating cost. Activated sludge processes often carry a large solids inventory. Managing the total inventory without interference is the key component of the optimization ...

  • EPA clamping down on Ozone standards

    The U.S. Environmental Protection Agency (EPA) is preparing to again lower its ozone standard. This action reduces the amount of ozone that is allowed in the air we breathe and thus forces more industrial sources to further reduce their air pollution emissions. In this white paper we look at: What will happen when the new ozone standard is finalized; and Ways to deal ...

  • 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.  ...

  • Thermodynamic analysis of the living cell: design of an exergy-based method

    A proper thermodynamic analysis of living-cell processes should elucidate the often-supposed sophistication of biochemical energy and material conversion, and it may provide valuable lessons on the design and operation of future technological processes. The difficulty however is to adequately account for the interaction of biochemical compounds with their complex intracellular environments, ...

  • Exergetic analysis of glucose metabolism

    The aim of this work is to analyse exergetically the glucose metabolism, which involves the steps of Glycolysis, Krebs Cycle and the Oxidative Phosphorylation. In order to achieve these goals, a methodology for the exergetic analysis of metabolism is presented. The exergy value of the metabolic compounds takes into account the compounds concentration in the environment, ionic dissociations, metal ...

  • Microbes Run the World

    Microbes run the world. They are the governing agents behind the conversion of key elements into vital biological forms. They remove toxins from their environments, and protect us from disease-causing organisms. Microbes do not, however, go to battle alone. Microbe armies live in complex communities that follow intricate processes and interactions to ensure environmental stability. Until ...

  • The PT pump - a true workhorse, even after 25 years of faithful service!

    1992 - The first large order It was back in the year 1992 when a MAN truck arrived in Apeldoorn from Van Kessel - a large Dutch dewatering company - to collect a deep loader trailer full with sound attenuated PT dewatering units from BBA Pumps. Jan Pellegrom, chief foreman at Van Kessel, remembers it as if it were only yesterday. "Back then we ordered our first 50 PT pumps for ...
