Demonstration of Resin Adsorption Techology for Treatment of VOCs in Groundwater
Untitled Document ABSTRACT Aberdeen Proving Ground (APG) has been a center for the development, testing, and manufacture of military-related chemicals since World War I, with industrial activities concentrated in the Canal Creek Area. Groundwater at APG has been impacted by these historical practices. The APG Installation Restoration Program (IRP) is implementing the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) process throughout APG. A Record...
Consideration of the Effects of Remediation Technologies on Natural Attenuation.
ABSTRACT: We have long understood and continue to improve our understanding of the geochemical conditions that favor biodegradation of petroleum hydrocarbons. Over the last several years our understanding of the conditions that are necessary for and/or promote reductive dechlorination of chlorinated hydrocarbons has improved substantially. Over this time in situ remediation technologies have proliferated. Many sites are being addressed with active remediation in conjunction with natural attenuation. For chlorinated...
Solid Waste Management: A Case Study of National Refinery Limited
Investigations have been carried out to assess and characterize the waste being generated in one of the largest petrochemical refinery of Pakistan. It was found that the refinery complex generates about 2000 metric tons of solid waste and about 0.55 million gallons of waste water per day. Besides these gaseous pollutants like H2S, CO, CO2 NO2, and particulate matter are also emitted in the atmosphere. Solid waste consisted of municipal waste, sludges from the API oil water separator, storage tank bottoms,...
Water Industry on the Eco Wave?
A wave of privatization is rolling through the water industry – at the environment‘s expense? In order to provide an answer to this question, the Environmental-Rating agency oekom research AG, Munich, put a number of water supply companies and manufacturers of water appliances to the environmental test. In results published today, oekom identifies the British water supplier Severn Trent as the environmental leader of the water supply group with a B grade in the overall Environmental-Rating. The Austrian water...
Ex Situ Biological Treatment for Soil, Sediment, and Sludge
The main advantage of ex situ treatment is that it generally requires shorter time periods than in situ treatment, and there is more certainty about the uniformity of treatment because of the ability to homogenize, screen, and continuously mix the soil. However, ex situ treatment requires excavation of soils, leading to increased costs and engineering for equipment, possible permitting, and material handling/worker exposure considerations. Bioremediation techniques are destruction or transformation techniques...
Ex Situ Biological Treatment for Groundwater, Surface Water, and Leachate
The main advantage of ex situ treatment is that it generally requires shorter time periods, and there is more certainty about the uniformity of treatment because of the ability to monitor and continuously mix the groundwater. However, ex situ treatment requires pumping of groundwater, leading to increased costs and engineering for equipment, possible permitting, and material handling. Bioremediation techniques are destruction techniques directed toward stimulating the microorganisms to grow and use the contaminant...
Understanding Crossflow Filtration
There`s a lot of attention being given to water availability and purity, with good reason. Obtaining enough water is a struggle in some areas. In others, water is tainted with contaminants. It is therefore predictable that regulations and economics will force careful water treatment and stress water re-use. Fortunately, there are water treatment methods that can help you meet the water quality challenges, and related water supply challenges, you face. Among these is crossflow filtration, a technology that has...
