  • How to Remediate under an Intersection with Horizontal Wells

    Roadway intersections within urban settings are arguably some of the most challenging areas for subsurface remediation. Many consultants tasked with remediation of challenging sites such as these become frustrated by the inability of a vertical remediation system to influence the area of concern and/or they are anxious that they will not efficiently bring their clients’ sites to ...

  • CASE STUDY - Surfactant Enchanced HVDPE Remediation of Petroleum Contaminated Soil, Bedrock and Groundwater

    Anionic: Have one or more negatively (-) charged groupings; commonly used in laundry detergent Cationic: Have one or more positively (+) charged groupings, typically poor detergents but well suited for use as germicides, fabric softeners and emulsifiers. Amphoteric: Contain both anionic and cationic groupings; prefer neutral pH and found in products such as hair shampoo, skin cleaners and carpet ...

  • Curtailing Contamination Hydrocarbon Engineering July 2017

    During planned shutdowns, the equipment in refineries and petrochemical plants has to be checked. The downtime can require several weeks when tanks, vessels, distillation columns, and pipes have to be drained and cleaned for i   maintenance or repair. Shutdowns are labour-intensive and require accurate scheduling and organisation between all projects, as often hundreds of workers are ...

  • Six months treatment cut 95% of priority PAH pollutants from coke oven effluent

    Six months treatment cut 95% of priority PAH pollutants from coke oven effluent. Citadel Biocat+TM provided the bioremediation in situ of 150,000 cubic meters of contaminated soil at a decommissioned coke oven effluent lagoon. Several decades of steel production had created a residue of significant amounts of polycyclic aromatic hydrocarbons (PAH’s), along with soluble components such as ...

  • Surface water polycyclic aromatic hydrocarbons (PAH) in urban areas of Nanjing, China

    The concentration, sources and environmental risks of polycyclic aromatic hydrocarbons (PAHs) in surface water in urban areas of Nanjing were investigated. The range of ∑16PAHs concentration is between 4,076 and 29,455 ng/L, with a mean of 17,212 ng/L. The composition of PAHs indicated that 2- and 3-ring PAHs have the highest proportion in all PAHs, while the 5- and 6-ring PAHs were the least ...

  • Biosurfactant production by Mucor circinelloides on waste frying oil and possible uses in crude oil remediation

    Biosurfactants are biocompatible surface active agents which many microorganisms produce. This study investigated the production of biosurfactants by Mucor circinelloides. The effects of different factors on biosurfactant production, including carbon sources and concentrations, nitrogen sources, and iron (II) concentration, were studied and the optimum condition determined. Finally, the ...

  • Using FTIR spectroscopy to measure hydrocarbon pollution in water

    According to the World Health Organization (WHO) and UNICEF’s 2015 Progress on Sanitation and Drinking Water report almost 700 million people around the world don’t have access to clean drinking water [1]. Poor water quality is beginning to return to the developed world too. The strain of population growth, intensified agricultural practices and continued industrial expansion have are ...

  • Enhanced Bio-Stimulation through Horizontal Wells

    Biosparging technology can be further enhanced when applied through Horizontal Remediation Wells. Since horizontal well systems typically have 4 to 10 times more screen footage in contact with the contaminated media than vertical systems, Horizontal Biosparge Wells can inject much greater volumes while maintaining the same low flow rates. This, in turn, leads to more rapid increases in dissolved ...

  • Enhanced Bio-Remediation of Wastewater

    Bioremediation has been used to treat hydrocarbon contamination in municipal wastewater for centuries. Most microbes used in bioremediation today are naturally occurringyetspecifically chosen and cultured versus being genetically modified. Bioremediation rivals techniques such as pump and treat extraction systems, as it provide cost savings for municipalities, as well as environmental savings by ...

  • Horizontal Recirculation Wells Remediate Fuel Oil Impacts

    Catering to the unique needs of the client and working hand-in-hand with the consultant, Directional Technologies approached a challenging remedial situation with flexibility and a new approach to re-task a horizontal injection well system to horizontal recirculation wells. Directional Technologies invites you to read another case study explaining how a project benefited from decades of ...

  • Nanobite Treated Contaminated Water – Fit to Drink! - Case study

    In 2010 the US Environmental Protection Agency, US Coast guard and BP Oil company invited Unirem Incorporated, the manufacturer of Nanobite Powder, to do an encapsulation test on crude oil polluted waters in the Gulf of Mexico. Nanobite Powder is the European trade name for a bio-remediation accelerator known in the USA as PRP (Petroleum Remediation Product). Nanobite Powder was ...

  • 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 ...

  • Nanobite Cleans up Coastal Oil Disaster in Spain - Case Study

    On November 13, 2002, the Greek tanker The Prestige began losing its cargo of #6 bunker crude oil after one of its tanks burst off the northwest coast of Spain. The Spanish government decided to allow the tanker to sink, despite concerns of widespread contamination. By December’s end, the tanker had lost 80% of ...

  • 93% of Oil from Railway tracks remediated - Case study

    Railway engines are predominantly diesel and as such  they discharge large volumes of oil, diesel and hydraulic fluids as they operate. These hydrocarbons contaminate the railway lines, stations and sidings on which the engines operate. For many years the hydrocarbon discharges have been ignored, with the tracks and surrounding lands becoming heaving contaminated. However, new ...

  • 99% of Oil from Leaking tanks remediated - Case study

    Spills and leaks from domestic and commercial oil tanks are a very common occurrence, caused either by the refilling of tanks or as the result of leaks. Very  often old metal tanks corrode and start leaking oil onto the ground around the tank. Also the tanks themselves become covered in dried hydrocarbons and become significantly discoloured, even black. Spilled oil can seep into the ground, ...

  • Nanobite remediates boyne river oil spill - Case study

    On the 6 September 2007, an oil spill from a fuel dump leaks into the beautiful Boyne River, County Louth, Ireland. Local wild fowl and their nesting areas are endangered, as is the local water supply. The coastguards deploy conventional booms to contain the spill but decide against the use of conventional chemical detergents because of the obvious damage to flora and fauna. ...

  • 99% of Interceptor contamination remediated - Case study

    What is an Interceptor Tank? An interceptor tank is a trap used to filter out hydrocarbon pollutants from rainwater runoff. It is typically used in road construction and on petrol station forecourts to prevent fuel contamination of the water table via runoff. Petrol interceptors work on the premise that some hydrocarbons such as petrol and diesel float on the ...
