Mining equipment cleaned with Ivey-sol prior to painting. used to remove residual oils and coal dust. successful application - Case Study
It was excellent, it worked very well It took all the oils and coal residues off in a fraction of the time it normally takes when using just high pressure hot water. It allowed us to clean and prep the equipment for painting in 1 verses 2 days". Post Treatment Water Following Ivey-sol Treatment of Heavy Waste-oil Contaminated Soils at a Refinery Site. The precipitation of the oil was effected ...

Full-scale STARx Hottpad to Treat Heavy Crude Oil Sludge at an Operating Oil Field - Oil Field in Kuwait - Case Study
Overview Wafra Joint Operations (JO) in Kuwait has been an operating oil field for almost 90 years. For more than 70 years, produced water was placed into solar evaporation ponds, growing to approximately 6 km2 in area. Beginning in the early-2000s, JO began remediation of the solar ponds, consolidating waste sludge and stockpiling contaminated soils. One of the final phases of this remediation ...

Separation and recovery of oil from oily waste materials using anaerobic thermal desorption unit technology
RLC Technologies, Inc.’s Anaerobic Thermal Desorption Unit (ATDU) is an exsitu, non-incineration technology designed to separate hydrocarbons from various matrices including oilfield waste, soil, sludge, sand, filter-cake, tank and tanker bottoms, organic-based hazardous waste and contaminated soil in a non-oxidizing atmosphere without destroying the hydrocarbons. This paper briefly ...

Heavy metal content in Thlaspi caerulescens J. et C. Presl growing on metalliferous and non-metalliferous soils in Central Slovakia
Thlaspi caerulescens is an important component of specific vegetation on mine wastes in Central Slovakia including those containing high soil concentrations of Zn, Pb and Cd in Banska Stiavnica and Cu in Spania Dolina. The population density of T. caerulescens varied in both metalliferous and non-metalliferous soils. Selective distribution of metals was observed in T. caerulescens: Cu and Pb ...

Characterization of Iron- and Manganese-cemented Redoximorphic aggregates in wetland soils contaminated with mine wastes
In wetlands, translocation of Fe and Mn from reducing to oxidizing zones creates localized enrichments and depletions of oxide minerals. In zones of enrichment, oxides cement matrix particles together into aggregates. In this paper, we describe the various Fe- and Mn-cemented features present in the 1 to 2-mm size fraction of mine-waste contaminated wetland soils of the Coeur d'Alene (CDA) River ...

A dynamite job? Cleaning up trinitrotoluene waste at the Apache powder superfund site.
The clean up of trinitrotoluene (TNT) wastes and contaminated soils from an abandoned TNT salvage operation is underway at the Apache Powder Superfund Site in Cochise County. Clean-up operations involved an unexploded ordnance (UXO) survey, on-site pre-burn of high-grade materials, excavation, and off-site disposal. Approximately 5,400 lb of high-grade TNT wastes (averaging approximately 33 ...

Lead Soil Contamination
What is Lead Soil Contamination? The keys to successful stabilization of lead soil contamination are: using the right reagent, using the right dosage and achieving good mixing of the reagent with the waste. Lead soil contamination involves encapsulation and chemical conversion during remediation projects rendering them non-leachable to allow disposal of a non-hazardous ...

The 1998 PCB Disposal Amendments: Guide to the 1998 PCB "Mega Rule"
INTRODUCTION On June 29, 1998, the U.S. Environmental Protection Agency (EPA) promulgated a sweeping series of changes in the PCB regulations under the Toxic Substances Control Act (TSCA). Commonly known as the Mega-Rule or PCB Disposal Amendments (due to its focus largely on waste management issues), this long-awaited rule encompasses more than 80 changes in the regulations and spans more ...

Characterisation of antimony, arsenic, cadmium, copper and tin occurrences at an abandoned sulphide-mining area
Contamination levels in top-soil, vascular plant and surface water samples from the Sao Domingos mining area, Portugal, were determined by Instrumental Neutron Activation Analysis (INAA) and Compton-Suppression Neutron Activation Analysis (CSNAA). The total levels of As, Cd, Cu, Sb and Sn are reported with a discussion of plant uptake and transfer coefficients. Comparative analysis of the same ...

Contaminant removal from dry and wet sands by thermal desorption
Infrared heating was used to determine the effects of temperature and moisture on the removal of selected organic compounds from contaminated sand matrices. Quartz sand was used as a chemically inert surrogate for soil to isolate the heat transfer and mass transfer effects without any chemical contribution from soil. The selected organic contaminants were 3-nitrobenzene sulphonic acid, sodium ...

The impact of an open waste disposal site on soil and groundwater pollution
A study has been carried out of a waste disposal site, located in the valley of a small creek, 3 km south of Canakkale city centre. The surface area of the site was around 101000 square metres, and the total amount of waste deposited at the site since 1990 was approximately 1001000 tons. The major risks of the dump are its closeness to the university campus area to the south, the airport to the ...

Solidification/Stabilization
Introduction: As for in situ solidification/stabilization (S/S), ex situ S/S contaminants are physically bound or enclosed within a stabilized mass (solidification), or chemical reactions are induced between the stabilizing agent and contaminants to reduce their mobility (stabilization). Ex situ S/S, however, typically requires disposal of the resultant materials. Under CERCLA material can be ...

Use of domestic sewage effluent for sustainable production of vegetable in Kashmir valley
Trace metals in discrete portions of knoll kohl were evaluated along with chemical composition of sewage effluent, irrigation water, and soil. High nutrients, Fe and Mn levels were noticed in the sewage effluent, whereas irrigation water showed recommended norms. Knoll kohl grown on sewage-irrigated soil accumulated sufficiently good amount of trace metals available to consumers. This study also ...

TECHNOLOGICAL INNOVATION IN RECYCLING FOR THE NEW SUSTAINABLE MODEL OF THE TEXTILE INDUSTRY
Europe generates more than 16 million tonnes of textile waste annually; 73% end up incinerated or in landfills and only 1% is recycled. Figures that make the textile industry one of the least sustainable on the planet. It is clear, therefore, that textile recycling has a fundamental role in the minimization and optimization of global waste management. In this sense, the future Waste Law, ...

How to turn human waste into disease-free fertiliser
Poor sanitation can contaminate drinking water, especially in rural areas. Unless properly dealt with, faeces and other human waste can pollute the soil and eventually wells, causing diseases such as diarrhoea. The EcoSanitation method provides a safe way to dispose of human waste. Today, a research project in Tanzania examines the potential of combining this system with a composting technique ...

Do I need a Phase I Environmental Site Assessment (Phase I ESA) and What do they cost?
A Phase I Environmental Site Assessment, often called a Phase I ESA, is generally performed on a commercial property usually as part of a sale/purchase or commercial financing by a broker or other lending institution. The objective is to protect a prospective buyer, property owner, or lending institution from some unforeseen aspect of the property that could affect the value or saleability of ...
