    Micro Pulse LiDAR remote sensing data are used to calculate a highly accurate Planetary Boundary Layer (PBL) height to improve plume models that help assess emissions sources. ...

  • Geomembrana HDPE Liner for Gold Mine Tailings Pond in Indonesia - Case Study

    Geomembrana HDPE liner, also known as geomembrane HDPE liner, is the  very low permeability synthetic membrane liner used with geotechnical engineering related material so as to contain fluid or gas migration in a human-made project, structure, or system. BPM brand high quality Geomembrana HDPE liner is manufactured with ...

  • Top 5 Differences between Micro Pulse LiDAR and Ceilometer Technology

    If you are evaluating backscatter LiDAR sensors for measuring aerosols, cloud vertical structure, and planetary boundary layer (PBL) heights, what factors should you consider in your comparison? It really comes down to a choice between the traditional analog technology used in ceilometers and the more recent advanced technology found in Micro Pulse LiDAR (MPL) sensors. ...

  • Multiple Instruments Work Together for a Better View of Air Quality

    Accurately identifying and quantifying particulate matter (PM) in the atmosphere is key to determining air quality. Researchers are particularly interested in PM that have a diameter of less than 2.5 micrometers because they are believed to contribute to heart and lung disease in humans and animals. These tiny particles are invisible to the naked eye and originate from power plants, fires, and ...

  • Rainwater harvesting for Harrow Boys School

    Harrow Boys School have included a 20,000 litre rainwater harvesting system within a new build boarding house. The rainwater harvesting system will collect, filter, disinfect and distribute the harvested rainwater for re-use in W.C. ...

  • Case Study - Water Resources Planning - Grand Forks, British Columbia

    Piteau Associates was tasked with developing a plan for preservation of water quality of public water supply wells within the community of Grand Forks, Columbia. They constructed a database of water quality and utilized EnviroInsite to show the spatial distribution and water quality trends of natural and anthropogenic ...

  • Risk management for water supply pipes

    In this paper, the risk of water supply systems as a combination of hydraulic analyses (consequence) and failure probability of pipelines based on the actual condition is discussed. On the one hand, a stepwise closing of pipelines calculates the influence on customer's supply which represents the importance of a pipe. On the other hand, based on existing failure statistics, age and material ...

  • Development of Microbial Growth in Fuels

    Microbial contamination is not specific to any one fuel type - marine, aviation, automotive and home heating fuels are all susceptible. Similarly there is no single specific organism that can be identified as being responsible for degradation and spoilage. As a general rule, wherever fuel and water come into contact in a storage or distribution system microbial contamination is likely to ...

  • Automated techniques for real-time shipboard determination of dissolved trace metals in marine surface waters

    This review compares methods that are currently employed for shipboard analysis of trace metals in seawater voltammetric, chemiluminescence and colorimetric methods. Instrumentation and methods are described for collecting surface seawater using pumping, with subsequent on-line analysis by stripping voltammetry. The review is illustrated with data for oceanic and coastal distributions of ...

  • Risk and Integrated Water Management (GWP, 2002)

    This paper attepmts to address different risk categories that water managers and water users are faced. It argues that risk managment is a distributive issue that cannot be treated solely as a technical matter best handled by experts. It involves the allocation of wealth and welfare between water sectors, ...

  • Recycled Water Quality

    Matching recycled water quality to beneficial uses requires an understanding of health and environmental requirements. Measures to achieve appropriate recycled water quality are determined firstly by treatment. The degree of treatment depends in part on the source and the hydraulic and biochemical characters of the wastewater. Overall recycled water outcomes may also be controlled ...

  • Bayesian modelling for water loss management decisions

    Bayesian networks and their associated methods are especially suited for capturing and dealing with uncertainty. They can be successfully applied both in engineering sciences and in reliability analyses of water distribution systems. In this paper we propose an interactive Bayesian network and a decision-theoretic system which intend to monitor water loss, predict likely outcome and select ...

  • MIEX® DOC Process for Removal of Humics in Water Treatment

    INTRODUCTION Humic substances present a significant problem in water treatment by causing colour in water, increasing required coagulant doses, providing precursors for disinfection by-products and causing re-growth in the distribution network. Humic compounds comprise more than 60% of natural organic matter in source waters. Dissolved organic carbon (DOC) is a “bulk” measure of the organic ...
