  • Monitoring of phytoplankton biomass and nutrients in a polluted stream

    The spatial and temporal variations in the concentrations of nutrients (NH4+, NO2−, PO43−, SiO4−) and chlorophyll a were monitored simultaneously in a slow-flowing watercourse (Saricay Stream, Turkey), which runs in a ruralurban gradient. Chlorophyll a concentrations ranged between 0.044 g l-1 and 206.15 g l-1 and, in general, the higher concentrations of chlorophyll a and ammonium were measured ...

  • Agricultural biomass monitoring on watersheds based on remotely sensed data

    There is a close quality relationship between the harmful levels of all three drought indicator groups (meteorological, hydrological and agricultural). However, the numerical scale of the relationships between them is unclear and the conversion of indicators is unsolved. Different areas or an area with different forms of drought cannot be compared. For example, from the evaluation of ...

  • 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 ...

  • Using ATP to Measure Living Biomass in Wastewater

    Bioreactors harness the ability of naturally-occurring microorganisms to break down environmental contaminants discharged from cities and industries. Becasue they are the engine driving the process, it is critical to closely monitor the quantity and quality of these microorganisms.  2nd Generation ATP provides wastewater treatment operators with the ultimate tool for accurately measuring ...

  • Dust monitoring

    Generally, two different approaches are used to measure the amount of dust deposited on a surface; Determination of the soiling of a surface, by a change in its properties; Determination of the quantity of dust deposited, by weight. WHAT IS DUST? Dust is a generic term used to describe fine particles that are suspended in the atmosphere. Dust comes from a wide variety of sources, including soil, ...

  • Cellular ATP – A Superior Measure of Active Biomass for Biological Wastewater Treatment Processes

    Biological wastewater treatment processes harness the ability of microorganisms to break down and assimilate organic compounds that, if left untreated, cause detriment to the environment. Although this process occurs naturally, engineered systems are used to accelerate the process by optimizing bioreactor conditions to promote higher-than-typical biomass concentrations, thus increasing the rate ...

  • Domestic wastewater treatment with a decentralized, simple technology biomass concentrator reactor

    A new type of membrane-like aerobic reactor initially designed for the degradation of hydrocarbon-derived groundwater contaminants was tested for treating domestic wastewater. The biomass concentrator reactor (BCR) consists of an enclosed, aerated tank containing a graded filtration medium with the function of solids separation, and was previously used to treat industrial wastewaters ...

  • Simulation of oxidation processes and biomass growth in intermittent sand filter

    Infiltration percolation is an extensive treatment process aimed at eliminating organic pollution, oxidizing ammonia and removing pathogens. The main purpose of this work was to improve, by means of a numerical model, the understanding of oxidation processes and biomass development in an intermittent sand filter. Hydrodynamic, dispersion and biologic parameters were calibrated and validated after ...

  • Monitoring of digesters in biogas plants

    Renewable sources of energy are gaining steadily in importance. Leading the way is the use of methane gas obtained from fermentation processes in biogas plants. Overloading such plants with excessive biomass may have drastic economic consequences and may even inactivate the biomass, necessitating a cost-intensive restart. Adding too little biomass also has financial consequences, as less ...


  • Monitoring of Algae Growth by TOC Measurement

    Global warming due to the excessive use of fossil fuels is becoming a problem which has prompted and accelerated the search for alternative fuels. Among the more attractive alternatives is biomass fuel, which is attracting considerable attention. Microalgae can be used for the production of oil without competing with food production, and to a greater extent than other biofuels, its ...

  • Anaerobic digestion of waste biomass from the production of L-cystine in suspended-growth bioreactors

    Waste biomass from the industrial production of the amino acid L-cystine contains above-average concentrations of organic pollutants and significant concentrations of nitrogen and sulfur. The specific biogas production (SBP) of waste biomass was monitored in parallel suspended-growth laboratory anaerobic bioreactors. After severe inhibition was observed, three different procedures were applied ...
