Bioremediation of Oil-Contaminated Soil in Kazakhstan - Case Study
Project Description The project consisted of the bioremediation of soil contaminated with mineral oils and approximately 3% crude oil. The soil matrix consisted of a fine grain composition with high salt contents. Therefore, a special bioremediation process employing static regeneration had been developed. The remediation procedure also included the sensor assisted addition of air and steam ...

Transport of Edible Oil Emulsions in Clayey Sands: 3D Sandbox Results and Model Validation
ABSTRACT: Injection of edible oils into the subsurface can provide an effective, low-cost alternative for stimulating anaerobic bioremediation processes. However, concerns have been raised about the effects of oil buoyancy and variations in aquifer permeability on the final distribution of oil in the subsurface. Three dimensional sandbox experiments were conducted to study the distribution of ...

SEB Surfactant Enhanced Bioremediation Process Improves F3 & F4 Bioremediation to CCME Guidelines - Case Study
SEB Surfactant Enhanced Bioremediation process successfully cleans >4,000 Tons of F3 and F4 hydrocarbon contaminated soils at a remote site in Alberta. The SEB process was employed when the subject soils would not respond well to a conventional ex-situ bioremediation treatment. So after a 20 month period of unsuccessful bioremediation; the client and environmental contractor contacted Ivey ...

Bioremediation of heavy metal contaminated aqueous solution by using red algae Porphyra leucosticta
Bioremediation is an effective process for the removal and recovery of heavy metal ions from aqueous solutions. In this study, red algae Porphyra leucosticta was examined to remove Cd(II) and Pb(II) ions from wastewater through biological enrichment and biological precipitation. The experimental parameters that affect the bioremediation process such as pH, contact time and biomass dosage were ...

CH#954 - Diesel/Gasoline Remediation
SITE OWNER: A Truck and Fueling Plaza SITE SURVEY: A tank area that had contained both diesel and gasoline tanks was discovered to have several leaks. The tanks from the pit area were removed. Definition and characterization revealed that not only the tank area was contaminated, but the contaminate plume had migrated under an area where a new building was being constructed. Initial ...

Nanobite bioremediates a Contaminated harbour - Case study
When a hydrocarbon is spilled on water, it is very visible – floating on the surface, a blue green sheen clearly visible. When applied to an oil spill on water, Nanobite Liquid will not mix with the water and become diluted. Within a minute it attaches to the hydrocarbon, bonding with it and creating a matrix – an agglomerated gel- that remains on the surface and cannot sink, no ...

Common Treatment Train for Fuels
A treatment train is the combination of different treatment technologies. A system diagram of a common treatment train for fuels is illustrated below. The fuel contaminated soil is first treated using a soil washing process. Water is injected at the up stream side of the contaminated site. Surfactant or other additives may be added to enhance the soil washing effect. Contaminated water is pulled ...

Biodegradation of Cypermethrin by pseudomonas in a batch activated sludge process
The biodegradation of Cypermethrin (20 to 125 mg/L) in an effluent using batch activated sludge was studied. Degradation was found to occur to a great extent only in the presence of Pseudomonas (IES-Ps-1) culture. Under aerobic conditions using mechanical aerators, Cypermethrin (20 mg/L) was almost completely degraded in just over 48 h at ambient temperature. Further loading of organic compound ...

Cadmium ion removal by electroflotation onto sewage sludge biomass
Non–living, anaerobically digested, Activated–Sludge (AS) was examined (laboratory–scale experiments) as possible biosorbent for the removal of cadmium from dilute aqueous solutions. The application of electroflotation to the suspended biomass, was investigated in this paper as an effective solid/liquid separation technique for the metal–loaded biosorbent particles. The main parameters ...

Surfactant desorption is key to successful PAH bioremediation
Formulations which are patented non-ionic surfactant mixtures used in the in situ and ex situ treatment of petroleum hydrocarbons, chlorinated solvents, heavy metals, and more recently PAHs, PCBs and MTBE type contaminated waste are involved in Surfactant Enhanced Bioremediation (SEB®) using Iveysol ®. These surfactant formulations have the ability to enhance soil biodegradation. During in ...

CH#952 - Oil Contaminated Soil
SITE OWNER: A National Overnight Express Package Company SITE SURVEY: Site and geological surveys revealed a contaminated area north of the facility and west of a diesel tank pit. The cause of the contamination was the result of two (2) underground storage tanks (UST™). One tank contained waste oil while the other contained new oil. Both tanks had been removed. A monitor well was ...

Integrated 3D physical-numerical modelling for simulating bioremediation of petroleum contamination in heterogeneous subsurface environment
This study presents physical-numerical modelling of petroleum contaminant transport and enhanced in situ bioremediation in heterogeneous subsurface environment. The approach is based on development of a three-dimensional multi-layered physical model coupled with a three-dimensional multiphase multi-component numerical model. An experimental scheme was designed to conduct 40-day benzene transport, ...

Cost implications of hydrogen donor selection for in-situ bioremediation of chlorinated solvents
The use of enhanced anaerobic bioremediation for treatment of chlorinated solvents in groundwater has increased at a rapid rate within the past three years. Since there are a number of different hydrogen donors that can potentially be used, it is important that practitioners understand the cost implications of the hydrogen donor(s) selected for the project. A comparative economic analysis is ...
