Reverse Osmosis and Nanofiltration Membrane Filtration Systems: Common Problems and How to Fix Them

Reverse osmosis (RO) and nanofiltration (NF) are membrane filtration technologies that are designed to remove solute ions and molecules from a pretreated liquid stream. Well-designed RO/NF units are compact and demand relatively little maintenance, making them an attractive alternative to conventional treatment trains. Even despite the merits of today’s efficient RO/NF technologies, it pays ...

In Situ Sediment Treatment Using Activated Carbon: A Demonstrated Sediment Cleanup Technology

This paper reviews general approaches for applying activated carbon (AC) amendments as an in situ sediment treatment remedy. In situ sediment treatment involves targeted placement of amendments using installation options that fall under two general approaches: 1) direct application of a thin layer of amendments (which potentially incorporate weighting and/or binding materials) to surface ...

Common Treatment Technologies for Fuels in Soil, Sediment, and Sludge

Common treatment technologies for fuels in soil, sediment, and sludge include biodegradation, incineration, SVE, and low temperature thermal desorption. Incineration is typically used when chlorinated SVOCs are also present with fuel, and not specified for fuel-only contaminated soil, sediment, or sludge. All types of biodegradation, both in situ or ex situ, can be used to remediate soils: ...

Remediation of the mercury-contaminated sediments in Svartsjoarna with Geotube - Case Study

The Challenge Svartsjoarna in Sweden are located near Paulistrom. Through the lake, a small river runs into the river Eman. This Eman river is considered to be one of the most valuable water courses in Sweden. The river has a very high diversity of fish species and animal like otter. Some parts of the river have very well developed meander systems. For these reasons, a remediation had to ...

Common Treatment Technologies for Inorganics in Soil, Sediment, and Sludge

The most commonly used treatment technologies for inorganics in soil, sediment, and sludge include solidification/stabilization (S/S), excavation and off-site disposal, and acid extraction. These treatment technologies are described briefly below. Solidification processes produce monolithic blocks of waste with high structural integrity. The contaminants do not necessarily interact chemically ...

Common Treatment Technologies for Radionuclides in Soil, Sediment, and Sludge

Unlike organic contaminants (and similar to metals), radionuclides cannot be destroyed or degraded; therefore, remediation technologies applicable to radionuclides involve separation, concentration/volume reduction, and/or immobilization. The most commonly used treatment technology for radionuclides in soil, sediment, and sludge is solidification/stabilization (S/S). This treatment technology is ...

Presumptive Remedies

A presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site. EPA is establishing presumptive remedies to accelerate site-specific analysis of remedies by focusing the feasibility study efforts. EPA expects that a presumptive remedy, when available, will be used for all CERCLA sites except under ...

Containment for Soil, Sediment, and Sludge

Containment treatments are often performed to prevent, or significantly reduce, the migration of contaminants in soils or ground water. Containment is necessary whenever contaminated materials are to be buried or left in place at a site. In general, containment is performed when extensive subsurface contamination at a site precludes excavation and removal of wastes because of potential hazards, ...

Common Treatment Technologies for Nonhalogenated VOCs in Soil, Sediment and Sludge

Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...

Positioning activated carbon amendment technologies in a novel framework for sediment management

Contaminated sediments can pose serious threats to human health and the environment by acting as a source of toxic chemicals. The amendment of contaminated sediments with strong sorbents like activated carbon (AC) is a rapidly developing strategy to manage contaminated sediments. To date, a great deal of attention has been paid to the technical and ecological features and implications of ...

Accelerated Bioremediation as an Alternative to Conventional Remedial Technologies.

ABSTRACT: Application of bioremediation as an alternative technology to expedite soil and ground-water remediation has been effective in reducing the concentration of hydrocarbons at an affordable cost. Bioremediation processes can be achieved by the addition of biological organisms into the soil and ground water which are contaminated and are microorganism deficient. The microorganism's ...

Common Treatment Technologies for Halogenated SVOCs in Soil, Sediment, and Sludge

Common treatment technologies for halogenated SVOCs in soil, sediment, and sludge include biodegradation, dehalogenation, incineration, and excavation with off-site disposal. All types of biodegradation, both in situ or ex situ, can be considered to remediate soils: in situ bioremediation, bioventing, composting, controlled solid phase, or landfarming. Slurry phase biological treatment is also ...

Data Requirements for Soil, Sediment, and Sludge

Site soil conditions frequently limit the selection of a treatment process. Process-limiting characteristics such as pH or moisture content may sometimes be adjusted. In other cases, a treatment technology may be eliminated based upon the soil classification (e.g., particle-size distribution) or other soil characteristics. Soils are inherently variable in their physical and chemical ...

Dredging and Shoreline Remediation

Many situations can complicate a shoreline’s integrity. These can range from flooding, hurricanes and man-made disasters and can even include aquatic harvesting and human recreation. Making efforts to protect a shoreline from these intrusions helps protect economic and recreational interests. Shoreline remediation is an investment in the overall economic and natural ...

In Situ Physical/Chemical Treatment for Soil, Sediment, and Sludge

The main advantage of in situ treatment is that it allows soil to be treated without being excavated and transported, resulting in potentially significant cost savings. However, in situ treatment generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in soil and aquifer characteristics and because the efficacy of the ...
