Abrasive Blasting and Salt Contamination: A Case History

ISCR-enhanced bioremediation is a term describing the remediation approach that combines zero-valent iron (ZVI), an organic hydrogen donor, and contaminant-degrading microbes (native or bioaugmented) in order to degrade contaminants in soil and groundwater. This approach is most commonly used for chlorinated contaminants, e.g. chlorinated ethenes.

Several studies have been conducted on the causes of premature wear in components. The figures vary from study to study but it is clear that external contamination of lube oil by silicon, or dust, is a major cause of accelerated wear. Particles of airborne sand and dust vary in size, shape and abrasive properties.

ARSENIC FACT SHEET - Water Quality Association

For example, contaminants can travel more quickly through sand than clay. The amount of rainfall in a given area will contribute to contamination as well; the more rain that falls, the more water is filtered down to recharge the aquifer. Rainfall that seeps into the ground can carry these contaminants into the aquifer. Contaminants

Permeable reactive barrier - Wikipedia

The use of ion exchange resins for the removal of iron and manganese has limited application due to the requirement that the contaminants be in dissolved form and at very low levels. This is due to the tendency of oxygen to react with the iron and managanes and therefore, increase the potential for plugging and buildup on the resin surface.
