  • Application of advanced Respirometry in the Nitrification assessment for different levels of Temperature, pH and Oxygen

    For a determined substrate concentration, the most significant environmental factors are temperature, pH and oxygen availability. The well known critical influence of those factors on the nitrification are here analyzed by making use of a specific software and advanced respirometry based on a dynamic LFS system, where the test conditions can be set in the corresponding test-settings board and ...

  • Tidal influences on unconfined water levels in wells.

    Tidal effects have the potential to measurably affect water level measurements and the estimation of groundwater flow direction and gradient. This has significant implications for the prediction and monitoring of contaminant plumes in coastal areas. Studies were conducted at two near-coastal sites in San Diego County, California, to evaluate the impact of tidal variability on the interpretation ...

  • Waste management and well-being

    There was the Industrial Revolution in Europe, followed by the Automobile Revolution in the early-to-mid 20th century. The Green and White ones followed after that in the Asian countries. The IT and telecom revolution has transformed lifestyles in the last two decades. After having nourished ourselves with the bounties of Mother Earth, it is time to give back, be grateful and conserve the ‘Gaia’ ...


  • Regional modeling of wells

    The ability to represent wells in a regional three-dimensional numerical groundwater model is crucial for many modeling exercises. Such wells can either be measurement wells where groundwater levels are measured as a function of time, or wells can be pumping wells in which water is removed from the well and a drawdown cone is created in the water table surrounding the well. There are numerical ...


  • IEG multi level sampling well (MLSW) case study - IEG Technologie GmbH

    The MLSW-system is used for the recovery of multiple high-quality samples of soil-gas and groundwater from numerous isolated horizons in a single standard borehole. The system is also used to accurately delineate contamination profiles in three dimensions, which is vital or the design, installation and monitoring of remediation systems. MLSWs also can be used for activly dispersing substances ...

  • Assessing sanitation service levels

    Conventional sanitation ladders rank sanitation in increasing complexity of technological options. However, sanitation improvement is not as straightforward as the concept of “a ladder” with incremental improvements, might suggest. For example, from the user perspective, a VIP toilet may in some circumstances be a better option than a septic tank system. There is a wide gap between ...

  • Scrubers with a level head

    The available methods for removing pollutants from a gas stream are numerous, to say the least. A popular method, scrubbers allow users to separate gases and solids by allowing the gas to come into contact with a liquid stream. In the end, the pollutants are washed away in the effluent, and the gas exits the system to be used in later processes or to be released into the atmosphere. For many ...
