  • Separation

    Introduction: Ex situ separation can be performed by many processes. Gravity separation and sieving/physical separation are two well-developed processes that have long been primary methods for treating municipal wastewaters. Magnetic separation, on the other hand, is a much newer separation process that is still being tested. Gravity Separation Gravity ...

  • Sedimentation structures

    Sedimentation structures are measures, which purify the surface runoff with the principle of sedimentation. The separation of solid from rainwater discharge (divided sewer system) can be carried out through: grit chamber rainwater sedimentation tank vortex separator system The dimensioning of plants, that work with sedimentation is done according to the allowed ...

  • Bioremediation Technologies for Marine Sediments

      USA – Baltic International Symposium on Advances in Marine Environmental Research, Monitoring and Technologies. Klaipeda, Lithuania. June 15-17, 2004 Global commerce relies heavily on waterborne transportation. Innovative, economical and environmentally sound ways to manage ...


  • The Power to Separate

    Gravity separators are effective and economical tools used to process wastewater and stormwater by removing pollutants such as sediment, hydrocarbons and debris through the process of sedimentation or flotation. Most separators have few or no moving parts, are easy to maintain and have a successful history of use in many different industrial, commercial and residential applications. Specifying ...

  • Environmental qualitative assessment of rivers sediments

    In this study, the concentrations of heavy metals (Ca, Zn, Cu, Fe, Mn, Ni) in thesediment of Shavoor River in Khuzestan Province in Iran has been investigated. After the library studies and field studies, six samples of water and sediment were taken from the river in order to evaluate heavy metal pollution in sediments. To determine the geochemical phases of metals in sediment samples the 5-step ...

  • Data Requirements for Soil, Sediment, and Sludge

    Site soil conditions frequently limit the selection of a treatment process. Process-limiting characteristics such as pH or moisture content may sometimes be adjusted. In other cases, a treatment technology may be eliminated based upon the soil classification (e.g., particle-size distribution) or other soil characteristics. Soils are inherently variable in their physical and chemical ...

  • Biosorptive separation of 'labile' fractions of copper and lead from river sediments and evaluation by differential pulse, anodic stripping voltammetry

    The 'labile' copper and lead metal contents of contaminated sediments were extracted in different chemical solutions and then subjected for biosorptive separations. The sorbents called 'AlgaSORB-sp' and 'AlgaSORB-ch' were derived from two different algae, viz., Spirogyra and Chlorella, respectively . The metal detection was made by differential pulse, anodic stripping voltammetry. The retention ...

  • In Situ Physical/Chemical Treatment for Soil, Sediment, and Sludge

    The main advantage of in situ treatment is that it allows soil to be treated without being excavated and transported, resulting in potentially significant cost savings. However, in situ treatment generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in soil and aquifer characteristics and because the efficacy of the ...

  • Analysis of PBDEs in Sediment Using GC-MS/MS

    Polybrominated diphenyl ethers (PBDEs) are brominated flame retardants (BFRs) widely used in plastics. Due to their toxicity and persistence, their industrial production is to be eliminated under the Stockholm Convention. Contamination from PBDEs is widespread in the environment, including in sediments. In order to determine PBDEs in sediments, they need to be separated from a large amount of ...

  • Ex Situ Thermal Treatment for Soil, Sediment, and Sludge

    The main advantage of ex situ treatments is that they generally require shorter time periods, and there is more certainty about the uniformity of treatment because of the ability to screen, homogenize, and continuously mix the soils. Ex situ processes, however, require excavation of soils leading to increased costs and engineering for equipment, possible permitting, and materials handling worker ...

  • 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 ...

  • Sequential fractionation of phosphorus in lake sediments of Northern Greece

    The amounts and forms of potentially mobile P in surface sediments from two lakes, Volvi and Koronia, located in Northern Greece were evaluated using a sequential chemical extraction. Five sedimentary P reservoirs were separately quantified: loosely sorbed P (NH4Cl-P), iron associated P (BD-P), calcium bound P (HCl-P), metal oxide bound P (NaOH-P) and residual P (organic and refractory P). ...

  • Sediment Spill Monitoring from Dredging, using the SediMeter

    Strategies for sediment spill monitoring and siltation measurements. The SediMeter allows a gradual increase in the equipment investment as conditions merit, from a single stand-alone logger, to a real-time monitoring network in which all previously purchased equipment can be included. Sediment spill causing siltation gives rise to two separate environmental problems: A suspended sediment plume ...

  • Common Treatment Technologies for Inorganics in Soil, Sediment, and Sludge

    The most commonly used treatment technologies for inorganics in soil, sediment, and sludge include solidification/stabilization (S/S), excavation and off-site disposal, and acid extraction. These treatment technologies are described briefly below. Solidification processes produce monolithic blocks of waste with high structural integrity. The contaminants do not necessarily interact chemically ...

  • Common Treatment Technologies for Fuels in Soil, Sediment, and Sludge

    Common treatment technologies for fuels in soil, sediment, and sludge include biodegradation, incineration, SVE, and low temperature thermal desorption. Incineration is typically used when chlorinated SVOCs are also present with fuel, and not specified for fuel-only contaminated soil, sediment, or sludge. All types of biodegradation, both in situ or ex situ, can be used to remediate soils: ...

  • Common Treatment Technologies for Radionuclides in Soil, Sediment, and Sludge

    Unlike organic contaminants (and similar to metals), radionuclides cannot be destroyed or degraded; therefore, remediation technologies applicable to radionuclides involve separation, concentration/volume reduction, and/or immobilization. The most commonly used treatment technology for radionuclides in soil, sediment, and sludge is solidification/stabilization (S/S). This treatment technology is ...

  • Ex Situ Biological Treatment for Soil, Sediment, and Sludge

    The main advantage of ex situ treatment is that it generally requires shorter time periods than in situ treatment, and there is more certainty about the uniformity of treatment because of the ability to homogenize, screen, and continuously mix the soil. However, ex situ treatment requires excavation of soils, leading to increased costs and engineering for equipment, possible permitting, and ...
