Evaluation of Mixing Energy in Laboratory Flasks Used for Dispersant Effectiveness Testing
Publisher: American Society of Civil Engineers
Abstract: The evaluation of dispersant effectiveness used for oil spills is commonly done using tests conducted in laboratory flasks. The success of a test relies on replication of the conditions at sea. We used a hot wire anemometer ...
Use of Membrane Bioreactor for Biodegradation of MTBE in Contaminated Water
Publisher: American Society of Civil Engineers
Abstract: An ultrafiltation membrane bioreactor was evaluated for biodegradation of methyl
Tracer Studies in Laboratory Beach Simulating Tidal Influences
Publisher: American Society of Civil Engineers
Abstract: Bioremediation of oil spills on tidally influenced beaches commonly involves the addition of a nutrient solution to the contaminated region of the beach at low tide to stimulate the growth of indigenous oil-degrading ...
Sedimentation of Oil-Mineral Aggregates for Remediation of Vegetable Oil Spills
Publisher: American Society of Civil Engineers
Abstract: A response alternative for floating vegetable oil spills based on sedimentation of negatively buoyant oil-mineral aggregates followed by anaerobic biodegradation in the sediments is under investigation. Sedimentation of ...
Tracer Studies in a Laboratory Beach Subjected to Waves
Publisher: American Society of Civil Engineers
Abstract: This work investigated the washout of dissolved nutrients from beaches due to waves by conducting tracer studies in a laboratory beach facility. The effects of waves were studied in the case where the beach was subjected ...
Effects of Nutrient Source and Supply on Crude Oil Biodegradation in Continuous-Flow Beach Microcosms
Publisher: American Society of Civil Engineers
Abstract: Ammonium and nitrate were used as nitrogen sources to support microbial biodegradation of crude oil in continuous-flow beach microcosms to determine whether either nutrient was more effective in open systems, such as ...
Steady Seepage in Trenches and Dams: Effect of Capillary Flow
Publisher: American Society of Civil Engineers
Abstract: Steady seepage from two-dimensional domains is investigated using a dimensionless formulation for variably saturated media that depends on three dimensionless parameters,
2D Variably Saturated Flows: Physical Scaling and Bayesian Estimation
Publisher: American Society of Civil Engineers
Abstract: A novel dimensionless formulation for water flow in two-dimensional variably saturated media is presented. It shows that scaling physical systems requires conservation of the ratio between capillary forces and gravity ...
