Photocatalytic degradation of naphthalene in offshore produced water
Offshore oil and gas industry has produced and discharged a considerable amount of produced on a daily basis. However, current treatment methods such as gravity separation are not effective in removing dissolved organic matters...
Membrane fouling remediation in ultrafiltration of latex contaminated water and wastewater
The goal of the present study was to remediate membrane fouling of latex effluent by altering the membrane surface charge or the ionic strength of simulated latex effluent either through the pH change or using anionic...
Optimizing Water Quality Sampling Through Application Of Real Time Ionic Concentration Regression Models
The Water Resources Management Division of the Department of Environment and Conservation performs routine water sampling to measure the physical and chemical parameters of select water bodies in Newfoundland and Labrador. Ionic...
Sea-Land Integrated Pollution Control Mode applied to Beidaihe Offshore Area
A Sea-Land Integrated Pollution Control Mode(SLIPCM) is extremely needed as the Beidaihe offshore area experiences the deterioration of water environmental quality and degradation of ecosystem service functions. In this study, a...
Cuttings Transport Evaluation in Deviated Wells
Cuttings transport efficiency is a measure of the extent to which cuttings are carried to the surface from a drilled hole. It quantifies the success achieved in freeing a well of drilled cuttings. It is also related to the...
Optimal PM2.5 emission reduction strategies for an industrial park based on China’s 12th five-year plan on air pollution prevention and control
Over the past decades, China has been undertaking extremely rapid industrialization and urbanization. Along with economic boom, many adverse environmental effects are emerging. Among them, it is of great significance for the...
Water Supply-Demand Management under Climate Change
This study aimed to investigate optimal multiple reservoir operations and water demand management considering climate change impact. In this study, conditional density estimation network creation and evaluation (CaDENCE) method...
Uncertainty analysis for propagation effects from statistical downscaling to hydrological modelingUncertainty analysis for propagation effects from statistical downscaling to hydrological modeling
To understand the water balance and environmental effects under climate change condition, hydrological models are always used to simulate the hydrological cycle and predict future scenarios by using global climate models (GCMs)...
Behavior of Corexit dispersants in the Gulf of Mexico after the Deepwater Horizon oil spill
Offshore Oil spills are of tremendous concern due to its enormous harm to economic and ecological systems. Corexit dispersants are used as an important combating agent for oil spills as they can dilute oil downward to water...
Possible Impacts of Climate Changes on Freshwater in Coastal Aquifers
Groundwater resources in coastal aquifers constitute a main source of freshwater in many regions around the globe. This is typically true in arid and semi-arid regions where rainfall is scarce and infrequent and the surface...
Development of a risk rank model for environmental risk assessment of abrupt water pollution accidents - with the case of Laoguan River Basin
In recent years, abrupt water pollution accidents have broken out frequently in watersheds and caused huge environmental and economic losses. These accidents have become one of the most serious environmental problems in China....
Offsetting the Destruction of Marine Fish Habitat During Coastal Development Projects in Canada
Under the Fisheries Act of Canada (2012), proponents of development projects are responsible for offsetting the destruction of freshwater and marine habitat if “serious harm” is expected to occur to fish supporting a commercial...
An Agent-based Simulation-optimization Coupling Approach for Device Allocation and Operation Control in Response to Offshore Oil Spills
The efficiency of offshore oil spill response not only relies on an efficaciously global decision/planning in devices combination and allocation, but also depends on the timely control for response devices (e.g., skimmers and...
Numerical simulations of oil spill trajectories in the Danjiangkou Reservoir in China
Oil spills in surface water happen each year in the world and significantly damage water quality and ecosystems. Numerical simulation of oil spill trajectories is helpful for risk assessment and risk controlling. Previous...
Comparison of Autoregressive Moving Average and State Space Methods for Monthly Time Series Modelling of Labrador and South-East Quebec River Flows
Time series data such as monthly stream flows can be modelled using time series methods and then used to forecast flows for short term planning. Two methods of time series modelling were reviewed and compared; the well-known...
Sludge Blanket Anaerobic membrane bioreactor (SB-AnMBR) Treatment of Prehydrolysis Liquor from the Dissolving Pulp Industry
Performance of innovative sludge-blanket anaerobic membrane bioreactors (SB-AnMBRs) was evaluated at mesophilic (35oC for 400 days) followed by thermophilic (55oC for 330 days) temperatures for the treatment of the...
A Study on Pollution in Livestock and Poultry Breeding in Shiyan City
With the investigation and research of agricultural ecology situation, the pollution characteristics of livestock manure were indicated by the statistical analysis of data as well as the effect of livestock and poultry breeding...
Study on Water-Atmosphere Interface Distribution and Concentration Fluctuation Intensities of Polybrominated Diphenyl Ethers in Great Lake
In this study, the water-atmosphere interfaces distribution and concentration fluctuation intensities of polybrominated diphenyl ethers (PBDEs) in Great Lake were analyzed. Based on the selected significant quantum descriptors...
Intelligent Multiparameter Fiber-Optic Sensing for Ocean Observation
With the increasing needs for the protection of marine and fresh water environment, there is surging demand for effective technologies to monitor different environmental parameters. Among different new technologies, fiber-optic...
Optimizing Water Quality Sampling Through Application Of Real Time Ionic Concentration Regression Models
The Water Resources Management Division of the Department of Environment and Conservation performs routine water sampling to measure the physical and chemical parameters of select water bodies in Newfoundland and Labrador. Ionic...
Long-Term Dependence of Annual Peak Flows of Canadian Rivers
Both short- and long-term dependence of the peak flow series of 90 Canadian rivers were analyzed two decades ago. It showed that although short-term dependence was practically absent for most of the flow series, significant...
Trace Element Analysis of Water with Inductively Coupled Plasma-Mass Spectrometry
Trace element analysis of the drinking water in the area of St. John’s, Newfoundland, Canada has been investigated by an Agilent 7700X inductively coupled plasma-mass spectrometry (ICP-MS). The results indicate that the levels...
