Influence of phosphate and citric acid on the phytoextraction of As from contaminated soils
The influence of phytoextraction in arsenic (As) contaminated soil on the phosphate and citric acid addition were investigated using Pteris vittata L. (Chinese brake fern). The As uptake in the fronds increased 85% in As–spiked soil when phosphate was added. The addition of citric acid for 2 weeks to the phosphate added soils resulted in the highest As uptake by 75% compared to only ...

Evaluation of sodium lignosulphonate for the remediation of chromium–contaminated soil and water
Commercial sodium lignosulphonate, a by–product of sulphite pulp leaching, was evaluated for the remediation of soil and water contaminated with hexavalent chromium. Two series of bench–scale tests were performed: (a) removal of chromium from water using reagent binding and membrane separation; and (b) stabilisation of chromium in the soil using chemical soil flushing. Water treatment tests were ...

Best technology for oily wastes and OBM cuttings in the Middle East-VacuDry vs. rotary kiln
This article explains the best available technology for oily wastes and OBM cuttings: When it comes to drill cuttings and contaminated soils treatment, numerous technologies are available on the market. For heavy oily wastes, especially OBM cuttings and oil sludges, only thermal processes have proved to be effective. For the last decade, few technologies have been competing for the latter oily ...

Bioremediation of ground water by treatment of soil at source with Vaporremed
A heating oil company during servicing of a home in PA released almost 150 gallons of heating oil that seeped into the basement and below. Ground water was shallow and PA DEP wanted to ensure that the contamination did not pollute the water. The environment company overlooking the cleanup decided to use VaporRemed to reduce the fumes. In three weeks time the level of contamination of the soil and ...

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 ...

Recovery of nitrogen pools and processes in degraded riparian zones in the southern appalachians
Establishment of riparian buffers is an effective method for reducing nutrient input to streams. However, the underlying biogeochemical processes are not fully understood. The objective of this 4-yr study was to examine the effects of riparian zone restoration on soil N cycling mechanisms in a mountain pasture previously degraded by cattle. Soil inorganic N pools, fluxes, and transformation ...

Heavy Metal Fixation Reagent for Soil - What is Heavy Metal Fixation?
Heavy Metal Fixation can be done by a chemical process that will prevent leaching of metals into the ground water during soil remediation projects. Different reagents are available which can stabilize lead, however different reagents required different cure times and addition of moisture, produce different amount of bulking, and produce material with different strengths, densities and other ...

Best technology for treating oily wastes in the Middle East – VacuDry® vs. rotary kiln
When it comes to drill cuttings and contaminated soils treatment, numerous technologies are available on the market. For heavy oily wastes, especially OBM cuttings and sludges, only thermal processes have proved to be effective. For the last decade, few technologies have been competing for the latter oily wastes. In particular, traditional indirect fired rotary kilns and VacuDry® vacuum ...

Bioremediation of petroleum contaminated Soils in Brazil Using AgroRemed
At Atuba at the corporate site of COPEL, a state owned utility company, soil was heavily contaminated with transformer oil due to a long history of contamination since 1964 probably due to unsafe practices of storage and cleanup. The level of contamination measures as TPH in soil was as high as 766,695 ppm and much of the contamination was at a depth of 1 meter. The site is located on a hill and ...

Improving the Predictability of Petroleum Brownfield Restoration
It’s no secret that the United States has an aging infrastructure problem. The public’s attention is focused on the repair of roadways and bridges, but there is also an ongoing initiative to address the existing infrastructure of legacy underground storage tanks, abandoned gas stations and truck stops, that are designated petroleum brownfields. As of July 2021, approximately 21 ...

Case Study - Crude oil and refinery waste
For years refinery and oil field waste had been dumped into the marsh adjacent to a large residential community. The waste oil had also started seeping into the local groundwater. The area included three large ponds including a bermed area, 3 meters deep, containing a mixture of 60% oil-tar in water. The total area held approximately 3,400 cubic meters (m3) of contaminated soil and sludge ...

Thermal Remediation of Karst Limestone – Redstone Arsenal, Alabama
Abstract: Electrical resistance heating (ERH) was used for the thermal remediation of two sites at Redstone Arsenal (RSA) near Huntsville, Alabama. Both sites feature karst limestone with heavy clay overburden. The two sites are located about five miles (10 km) apart, but differ considerably in the characteristics of the limestone. At site RSA-053, the heavy clay is underlain by very hard, ...
