This paper illustrates the possibilities of applying what is essentially a physical soil-washing technique for treatment of soil contaminated by semi-volatile hydrocarbons in order to reduce the level of pollution to that permitted by Italian regulations. The ground around a factory producing lubricating-oil additives consists of silty-sandy soils, which have long been contaminated by heavy hyd...
In this study, the identity and distribution of plants and the structure of their associated rhizobacterial communities were examined in an oil-contaminated site. The number of plant species that formed a community or were scattered was 24. The species living in soil highly contaminated with total petroleum hydrocarbon (TPH) (9,000-4,5000 mg/g-soil) were Cynodon dactylon, Persicaria lapathifoli...
Production and spillage of petroleum hydrocarbons which is the most versatile energy resource causes disastrous environmental pollution. Elevated oil degrading performance from microorganisms is demanded for successful microbial remediation of those toxic pollutants. The employment of biosurfactant-producing and hydrocarbon-utilizing microbes enhances the effectiveness of bioremediation as bios...
: The present study evaluated the effect of integration electro-kinetic (EK) oxidation with sonication degradation diesel in a hydrocarbon contaminated wastewater. operational parameters including initial pH (3 - 9), (100 300 W), voltage (0.5 3 V/cm), and reaction time (60 150 min) were studied consecutively. highest total petroleum (TPH) destruction rate 40% was achieved at 5. Also, increasing...
An experimental scrutinization of bioremediation crude oil polluted soil using furnace pyrolyzed comingled-biochar containing poultry litter, pine wood and rice straw char made at different proportions was carried out in the present study. The experiment performed five stages which include investigation, biochar production, characterization, total petroleum hydrocarbon (TPH) remediation via gre...
Interaksi sinergis antara tanaman-bakteri dapat digunakan untuk meningkatkan kinerja fitoremediasi tanah yang terkontaminasi hidrokarbon (HC). Penelitian bertujuan karakterisasi plant growth promoting rhizobacteria: Azotobacter sp. dan Pseudomonas dalam limbah minyak bumi menggunakan tanaman sorgum (Sorghum bicolor L.). rancangan acak kelompok faktorial (RAK-Faktorial) terdiri dari inokulasi se...
امروزه آلودگی خاک به انواع مواد نفتی(tph : total petroleum hydrocarbon ) از جمله معضلاتی است که محیط زیست انسان و سایر موجودات زنده وابسته به خاک را با خطر جدی مواجه نموده است. پاک سازی این آلاینده در خاک به دلیل سمی و شیمیایی بودن از اهمیت بسزایی برخوردار است. موضوع اصلی پیگیری شده در این پایان نامه بررسی روش خاک شویی به کمک شوینده سورفکتانت به عنوان یکی از روش های فیزیکی-شیمیایی جهت پاک سازی...
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 replications of the fo...
Produced water (PW) and spent oil-based wastewaters are some of the largest mineral oil produced. Due to high toxicity hydrocarbons, several countries set stringent discharge limits its treatment is compulsory before discharge. In this work, biological coupled with production bacterial lipids demonstrated in sequential batch airlift reactors (SBAR). Two SBAR (2 L working volume) were used for P...
Leakages of oil products derived from petroleum can affect the environment, even causing risks to human. In order to study all the substances that usually are found in a petroleum leakage, it becomes interesting to apply the study to the Total Petroleum Hydrocarbons (TPH) fractions which have similar physico-chemical properties. The purpose of this paper is to perform a suitable risk specific s...
