Centralised treatment of oil sludge and other industrial waste
Centralised treatment of various sources of industrial waste has been established in many European countries over the last decade. Many facilities are still equipped with non state of the art technology and therefore cannot fulfil the broad field of applications with regard to industrial waste remediation. econ's international client decided to be one step ahead and erected a new econ industries ...

A New Apparatus for the Evaluation of Electro-Kinetic Processes in Hazardous Waste Management
Possible uses of electro-kinetics for hazardous waste site remediation are being investigated. This paper describes a new apparatus which has been specifically designed, fabricated, and assembled to evaluate the viability, feasibility, practicality, and potential costs of these conceivable techniques experimentally. Results of studies on the existence of electro-osmotic flow in compacted clay and ...

Manufacturing facility cleaning case study
The Challenge A large Industrial manufacturing facility found that their process used to perform the necessary tasks was creating an undesirable accumulation of heavy metals dust throughout the entire plant. Not only was this a potential health risk to the plant workers, there was a structural and safety problem because the dust could spark and cause a fire or explosion. The Enviro-Vac Solution ...

No Small Task: Regulating Nanotechnology To Ensure Safety, Maximize Benefits
Nanotechnology is about engineering at the same size as large molecules like DNA, which is two nanometers wide — a nanometer is a billionth of a meter — or even smaller. Smallness has its virtues. Nanoscale zinc oxide diffracts light better, making a better sunscreen. Similarly, ultrathin nanoscale films are improving the efficiency of cell phone screens and photovoltaics. In the future, ...

Filter bed remediation - Case Study
Biological filter beds usually consist of a mineral media over which effluent to be treated percolates. The media becomes host to a biomass which is grazed by a series of more complex organisms. If the growth of the biomass is greater than the rate at which the grazing occurs then the biomass film will accumulate in the bed. This will block the interstices of the media and restrict effluent ...

The use of vetiver (Vetiveria zizanioides L.) for the remediation of wastewater discharged from tapioca factories
Three experiments were conducted to study the potential use of vetiver (Vetiveria zizanioides L.) to remediate wastewater discharged from a tapioca factory. Two experiments studied the tolerance of vetiver to grow in wastewater, and the other studied the factors influencing the effectiveness of vetiver for the remediation of the wastewater. Vetiver grew well in all wastewater preparations and was ...

Properties and Behavior of Radionuclides
For the purposes of this document, radionuclides should be considered to have properties similar to those of other heavy metals.This does not imply that all radionuclides are heavy metals, but that the majority of sites requiring remediation of radioactively contaminated materials are contaminated with radionuclides that have similar properties. Like metals, the contaminants of concern are ...

Evaluating DNAPL Recovery System Performance GeoTrax Survey - Case Study
Aestus performed our GeoTrax Surveys to asses the performance of a DNAPL recovery system installed within a waste pit at a hazardous waste landfill. The two remediation wells along our survey transect had been “clean” for two years prior to our confirmation survey work. The GeoTrax Survey results indicated that recovery wells have achieved significant reduction of DNAPLs near the ...

Asbestos contaminated soil case study
An active gypsum manufacturing facility discovered they had a large area of gypsum waste containing asbestos mixed with soil at the back of their property. The waste had accumulated over the years before the dangers of asbestos were known and now required remediation due to communication wires buried in the waste. Excavators could not be used due to the presence of the communication wires that ...

Application of SpillRemed (Industrial) at Ronson Aviation, NJ
Application of bioremediation products for routine maintenance of facilities receiving waste oil is being practiced by Ronson Aviation, NJ for several years and they have found that their site is now free from any residual fuel in the waste stream. All of the above remediation has been accomplished at under USD 300.00 per OWS per year, proving our point that oil contamination remediation need not ...

A simple method to check for natural attenuation downstream of abandoned waste disposal sites
Evaluations of waste sites are based on the assessment of whether conditions for Natural Attenuation (NA) processes are favourable. A method is proposed as a first check for effects of NA in the groundwater emissions. For the application of the method, concentrations of the concerned substance and of a tracer must be available at observation wells at different distances from the source, ...

Improving the sustainability of source removal
Abstract:There is a growing recognition of the importance of making hazardous waste remediation more sustainable, and thereby minimizing its economic, environmental and social impacts. The attention of sustainable remediation practitioners has thus far been focused on remediation of lower concentration targets, such as dissolved plumes, where reliance on green techniques that mimic naturally ...

Use of vermiculture technology for waste management and environmental remediation in Argentina
Throughout the world, there have been increasing interests in the recycling of wastes for sustainable development. This especially applies for organic materials of municipal and agro-industrial origin. Recycling initiatives in Argentina are still incipient. In the last years, the use of earthworms for stabilising organic wastes has been evaluated. In this paper, the authors compile the research ...

Less and More : Why You Should Pump Slurries with a Peristaltic Pump
LESS WATER Peristaltic Pumps Use Less Water Hose pumps can circulate slurry SGs of 1.6 to 1.8 or up to 80% solid content. The traditional centrifugal pump loses efficiency when the slurry SG reaches 1.3 or 30% solids. With this limitation, slurry pumps have significant process water demands : on a plant processing 70 tonnes of ore per hour, every time a hose pump replaces a process slurry pump, ...
