  • PeCOD® Case Study #13 Airport De-Icing

    De-icing of aircrafts and airfield pavement is important to ensure the safety of passengers and cargo operators. These operations can have negative environmental impacts, due to the presence of ethylene glycol and propylene glycol, which contribute to high levels of BOD in surface water.  Regulations are in place to ensure that waste from de-icing operations are properly collected and ...

  • Festival music never sounded so good

    Music festivals have been popular for decades, with millions of attendees across the globe at events such as Lollapalooza in Argentina and Chile, Glastonbury in England or Coachella in the United States, to name but a few. Part of the attraction of festivals is the loud music but this can damage hearing and also be nuisance to those in the surrounding area. Jochen Schaal, Managing Director at ...

  • Combined effects of nutrient enrichment and inorganic sedimentation on benthic biota in an experimental stream system

    Sedimentation and nutrient loading are among the most prevalent threats to fluvial ecosystem integrity. This study employed artificial streams (mesocosms) to simulate individual and combined impacts of nutrient enrichment and deposited fine sediment on benthic biota. Ninety-six circular mesocosms were used in a 21-day crossed experiment that measured the impact of three substrate compositions ...

  • Assessing methods for estimating roughness coefficient in a vegetated marsh area using Delft3D

    A Delft3D-FLOW model was used to simulate tidal flow in Davis pond marsh in Louisiana, USA. The study area is a freshwater marsh consisting of one main channel and floodplain. Vegetation-induced flow resistance greatly influences tidal flow dynamics in the marsh. This study evaluated eight approaches to estimate vegetation roughness, including two constant Manning's n values, four empirical ...

  • Shallow groundwater quality assessment: use of the improved Nemerow pollution index, wavelet transform and neural networks

    Shallow groundwater is generally of great interest to the community due to its easy availability. However, it is very sensitive to external stimulus. In this paper, shallow groundwater quality is assessed and classified with improved Nemerow pollution index, multi-layer perceptron artificial neural network (MLP-ANN) optimized with a back-propagation algorithm and wavelet neural network (WNN) ...

  • Microbiological contamination of water pans in Baringo County

    Water pans constitute the main source of rural water supply in Baringo County. This study sought to assess the spatial-temporal variation of total coliforms, Escherichia coli, Fecal streptococcus and Salmonella species in the water pans. A sanitary survey was conducted to observe the potential sources of microbial contamination on the water pans. Water was ...

  • 4 Types of Contaminants in Water

    The EPA says that there are 4 type of water contaminants: physical, chemical, radiological, and biological. Its definition includes anything that is not an actual water molecule. That means that naturally occurring things like sediment and water weeds are considered contaminants along with things like oil and uranium. Chances are good that the type of contaminants your company needs to keep out ...

  • Determinants of the use of alternatives to arsenic-contaminated shallow groundwater: an exploratory study in rural West Bengal, India

    Shallow groundwater containing toxic concentrations of arsenic is the primary source of drinking water for millions of households in rural West Bengal, India. Often, this water also contains unpleasant levels of iron and non-negligible fecal contamination. Alternatives to shallow groundwater are increasingly available, including government-built deep tubewells, water purchased from independent ...

  • Evaluation of sludge handling using acidification and sequential aluminum coagulant recovery: case study of El-Sheikh Zayed WTP

    Huge amounts of water treatment sludge are wasted annually in Egypt. One common practice of sludge handling is to discharge into waterways or by disposal after drying into landfills. Currently, there is a critical need for sustainable solutions that provide environmental protection as well as benefits for water producers. Coagulant recovery is not new but is still a good solution for sludge ...
