Proficiency test of non-target screening with gas chromatography mass spectrometry to confirm a detected contamination of raw and drinking water

Much of the water supply industry has implemented online monitoring and warning systems for chemical or biological contaminations. When a contamination is detected, further investigations are necessary to confirm or to cancel the initial alarm. The proficiency of a non-target screening approach with solid phase extraction and GCMS in full-scan mode was examined. A selection of pesticides and ...

Testing of Oil Recovery Skimmers in Ice at Ohmsett - The National Oil Spill Response Research & Renewable Energy Test Facility

Abstract The mechanical recovery of oil in ice-infested water presents unique and difficult clean-up challenges. Ice can impede the movement of spilled oil making it less available for removal by the active components of oil recovery skimmers. Ice and slush that is recovered with oil can jam the skimmer, pump inlets and hoses and can provide an environment for enhanced emulsion formation. ...

Validation of a new standardized test method for the freshwater amphipod Hyalella azteca: Determining the chronic effects of silver in sediment

Environment Canada has developed a new 42 day sediment toxicity test method that includes a reproduction test endpoint with the freshwater amphipod Hyalella azteca. Due to concerns that existing standard methodologies, where adults are transferred to a water‐only exposure before release of their first brood at day 28, will lead to internal contaminant depuration and loss of sensitivity, the EC ...

The modelling of lead removal from water by deep eutectic solvents functionalized CNTs: artificial neural network (ANN) approach

The main challenge in the lead removal simulation is the behaviour of non-linearity relationships between the process parameters. The conventional modelling technique usually deals with this problem by a linear method. The substitute modelling technique is an artificial neural network (ANN) system, and it is selected to reflect the non-linearity in the interaction among the variables in the ...

Fit for Changes

Changing conditions are a huge challenge for pump operators. Not only can the operating costs skyrocket, but the risk of production downtime can too—which is unacceptable, especially in businesses like oil and gas, power, and water. The example of a water injection pump retrofit shows how Sulzer helps to ensure reliable operation and to reduce energy consumption. A major oil company ...
