wastewater mercury monitoring Articles

  • Is there mercury in your industrial wastewater discharge?

    An assessment of sampling locations for three industrial wastewater effluent piping systems is presented. The assessments provided demonstrate that by installing sampling ports at the appropriate location along an effluent stream’s piping system, truly representative samples can be collected. These real and accurate results scientifically prove that a specific industrial wastewater ...

  • Predictors of mercury spatial patterns in San Francisco Bay forage fish

    Pollution reduction efforts should be targeted towards those sources that result in the highest bioaccumulation. For mercury (Hg) in estuaries and other complex water bodies, carefully designed biosentinel monitoring programs can help identify predictors of bioaccumulation and inform management priorities for source reduction. We employed a probabilistic forage fish Hg survey with hypothesis ...

  • KPDES Permit Compliance: Metals in Wastewater Effluent at Fort Knox

    ABSTRACT Prior to constructing a new FOTW, Fort Knox had a history of exceeding KPDES effluent limitations for ammonia and BOD. The new 6 MGD FOTW solved the problem, but metals exceedances became an issue. The exceedances could be linked to several factors: low water-quality based effluent limitations (WQBELs) on the new KPDES permit, high background concentrations of some metals, and high ...

  • Fabrication and evaluation of an attapulgite membrane as the filter for recycling blowdown water from industrial boilers

    Continuous blowdown water (CBW) from industrial boilers is of great quantity and energy, and therefore worth recycling. According to the data from a long period of monitoring, carbonate and sulfate were documented as the main contaminants in CBW. Herein, an attapulgite (ATP) membrane was prepared on a macroporous Al2O3 support through solid state sintering. The prepared membrane ...

  • A Comparison Of Microbial Repair Mechanisms With Low Pressure And Medium Pressure UV Lamps

    Introduction It is well-known that bacteria and other microorganisms are capable of repairing their DNA following damage by ultraviolet (UV) radiation. Known as ‘reactivation’, it is a natural defense mechanism that has evolved over millions of years. Some microorganisms need visible light in order to repair their DNA (known as ‘photoreactivation’), while others can repair their DNA without light ...

  • Water Quality Models

    ' In order to determine the impacts of a particular discharge on ambient water quality, it is usually necessary to model the diffusion and dispersion of the discharge in the relevant water body. The approach applies both to new discharges and to upgrading of existing sources. This note provides guidance on models that may be applicable in the context of typical Bank projects.' Introduction ...
