  • A quick guide to oil analysis for engine test applications

    Reliability testing is a very important component of new engine development. Engineers need to fully understand and chart the engine lifetime performance under a variety of conditions before mass production may be considered. Many important performance data parameters are collected in real time through the many different types of sensors that are connected to the engine in the test cell and oil ...

  • 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 ...

  • How Tire Shredding Protects Wildlife

    One of the most revolutionary inventions in the history of mankind was the wheel, and the best upgrade to that invention was the rubber tire, which overcame the limitations of wooden or metal wheels and made it possible to have smooth rides at fast speeds. However, there is a significant drawback to using rubber tires: eventually, they get too worn out to be useful as tires anymore and have to ...

  • How industrial water filtration can improve efficiency and save you money

    Over the course of the past couple of decades, industrial water filtration has become one of the most important considerations for the average manufacturing facility in North America. These concerns have only increased as water supplies have dwindled and wastewater contamination standards have become more stringent. All of this has led to the need to choose the right industrial water filters and ...

  • 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 ...

  • Turning coolant contamination into a profitable oil-reclamation program

    What started out as an expensive problem of metalworking coolant contamination has been turned into a profitable oil-reclamation program. Van Huffel Tube of Warren, Ohio – a manufacturer of welded tubing – was spending about $3,000 per year in recharging a soluble-oil coolant tank that would become contaminated with tramp lubricating oil. The 1,000 gallon tank had to be recharged ...

  • Water repellency in oil contaminated sandy and clayey soils

    Two sites from a humid tropical environment were studied with respect to soil water repellency caused by hydrocarbon contamination. Samples were analyzed for water repellency (molarity ethanol droplet method), total petroleum hydrocarbons, acute toxicity (Microtox) and field capacity. At both sites, water absorption times were ...

  • Treatment of Oil-Contaminated Soils for Identification and Classification

    An experimental investigation was performed to evaluate the effects of oil contamination on soils and to establish a methodology to identify and classify contaminated soils. Identification and classification tests were performed before treatment, cleaning, stabilization, or disposal of contaminated soils.There are no standards for identification and classification of contaminated soils. ...

  • Characterization and treatability of a contaminated soil from an oil exploration zone

    Abstract: A crude contaminated soil, arising from an oil production zone in Tabasco, Mexico was studied. A sample of about 40 kg was dried and screened through meshes 10-100. Total petroleum hydrocarbons and 6 metals (Cd, Cu, Cr, Ni, V and Zn) were determined to the different portions. For soil which passed mesh 10, six non-ionic, three anionic and one zwitterionic surfactant solutions ...

  • Environmental and health risk assessment of an oil contaminated site in the Mexican tropical southeast

    The aim of the present study was the environmental and health risk assessment of the oil contaminated soil in the Mexican tropic. The case is based on the total petroleum hydrocarbons (TPH) and polycyclic aromatic (PAH) soil contamination resulting from the activities of the oil industry over 70 years. The results of this study were estimated using CalTOX, a multimedia exposure model. The ...

  • Treatment of wastewater contaminated with detergents and mineral oils using effective and scalable technology

    In this work, effective, cheap and scalable methodology is introduced to treat oily wastewater. The water produced from car-wash processes was utilized as a model because it has various pollutants – oil, lubricants, detergents, solid particles, etc. The results showed that the turbidity and chemical oxygen demand (COD) values dramatically decrease by using the proposed treatment process, ...

  • North Holmwood, Surrey case study - Homes potentially contaminated by fuel oil

    Fearful residents of houses on land potentially contaminated with fuel oil in North Holmwood, Surrey are concerned about the impact of past industrial land use on their property prices. The extent of contamination has varied from one house to another but clearly demonstrates the importance of knowing what activities were carried out before the development was constructed back in 1985. Mole Valley ...

  • How to Deal with Oils When Treating Contaminated Construction Dewatering Water

    Oils are defined as organic materials that are not completely dissolved in water and present in the forms of sheens, globules, droplets. If present at a construction dewatering site, oil will most likely need to be removed from the contaminate water before discharge in order to meet the discharge limits for oil & grease (O&G) and/orspecific contaminants of concern (COC) that oil may carry ...

  • Phytoremediation of Alkylated Polycyclic Aromatic Hydrocarbons in a Crude Oil-Contaminated Soil

    Abstract  Phytoremediation uses plants and their associated microorganisms in conjunction with agronomic techniques to remove or degrade environmental contaminants. The objective of the field study was to evaluate the effect of vegetation establishment plus fertilizer addition on the biodegradation of alkylated polycyclic aromatic hydrocarbons in a crude oil-contaminated soil. Four ...


  • Germination and growth of six plant species on contaminated soil with spent oil
