  • Aerobic microbial transformations of pipe and silt trap sediments from combined sewers

    ABSTRACTOrganic matter in sediments from pipes and silt traps in combined sewers was divided into fractions with different settling velocities. Biodegradability of organic matter for these fractions was characterised based on results from a conceptual model of aerobic transformations of resuspended sediments calibrated on oxygen utilisation rates. Pipe sediments as well as silt trap sediments ...

  • Pilot plant study for one year: water quality management and algal control of sustainable urban stormwater ponds

    Pond structures as cost-effective "source control" drainage techniques that can be applied to reduce the risk of downstream flooding and to recycle stormwater. There are no widely accepted performance and water quality management data on stormwater ponds, yet there is a need for operation and maintenance guidelines, coupled with data on reliability, economics and public acceptance. The purpose of ...

  • Soil Fracturing

    Introduction Fracturing is an enhancement technology designed to increase the efficiency of other in situ technologies in difficult soil conditions. The fracturing extends and enlarges existing fissures and introduces new fractures, primarily in the horizontal direction. When fracturing has been completed, the formation is then subjected to vapor extraction, either by applying a vacuum to all ...

  • Fountain creek sediment collector - case study

    An innovative sediment management method, a 30-ft wide, high capacity, Sediment Collector, is currently installed in Fountain Creek, Pueblo, Colorado upstream of the confluence with the Arkansas River.  This installation is intended to demonstrate a new technology available to reduce the need for dredging.  The purpose of the Sediment Collector is to demonstrate the capability to lower ...

  • Living with floods in the Mahanadi Delta, India

    In October 2013, one of the fiercest cyclones to hit the Bay of Bengal for many years made landfall on the low-lying delta coast of the Indian state of Odisha. With winds battering the coastline at more than 200 kilometres per hour, the structural damage from cyclone Phailin was intense. Thousands of straw, timber and bamboo homes were destroyed across the delta of the River Mahanadi, one of ...

  • Spray Painting: GT Motors

     Background GT Motors (GTM) is a small panel beating and spray painting workshop established in 1964, with a current of workforce of four. GTM currently repairs and refinishes approximately 30 cars a month from a largely private and growing customer base. Like many environmentally responsible operators, the firm reuses and recycles as much of the wastes generated in their ...


  • Bioremediation/natural attenuation continues after ISCO treatment

    Scientists and engineers from the private sector and EPA are evaluating the potential for in situ bioremediation and/or natural attenuation to successfully treat residual soil and ground-water contamination after source-area in situ chemical oxidation (ISCO) treatment. The studies were prompted by concerns that the two treatment technologies may be incompatible due to detrimental impacts on ...

  • Real-time TOC tightens effluent control at Greencore

    A food manufacturing facility in Selby has installed a new continuous TOC (Total Organic Carbon) monitor, ‘the BioTector’ which has dramatically improved the site’s capability to refine and improve the plant’s wastewater treatment process. As a result the plant is better able to quickly respond to changes in the influent. Greencore Foods is a leading player in the food ...


  • Erosion and Sediment Control: Navigating NPDES Regulations, the SWPPP, and Techniques for Compliance

    Erosion and Sedimentation: Why Are They a Problem? The US Environmental Protection Agency lists sediment as the single most common pollutant in rivers, streams, lakes, and reservoirs. With all the potentially harmful chemicals and substances in the world, it seems odd to many people that sediment—dirt, essentially—is singled out as the major culprit. Yet these particles of ...

  • TURBIDITY BARRIER ULTIMATE GUIDE

    TURBIDITY BARRIER ULTIMATE GUIDE Definition Floating turbidity barriers (a.k.a. silt curtains, silt boom, sediment curtain) are a temporary in-water sediment barrier consisting of a continuous geotextile fabric curtain suspended from a flotation device on the water surface and held in ...

  • The In Situ Bioremediation/Groundwater Remediation Process

    In-situ groundwater bioremediation is a technology that encourages growth and reproduction of indigenous microorganisms to enhance biodegradation of organic constituents in the saturated zone. In-situ groundwater bioremediation can effectively degrade organic constituents which are dissolved in groundwater and adsorbed onto the aquifer matrix. The Adventus In Situ Bioremediation/Groundwater ...


  • Crossflow Membrane Filtration High-Purity Water Systems

    INTRODUCTION As the electronics industry continues to provide us with such products as high resolution television, notebook size portable computers and cars with automatic navigation systems, it becomes necessary to produce semiconductors with finer device geometries to allow for efficient placement of more circuits per a given area. This requires increased control of a semiconductor's material ...
