System E.T. 20 is a proven biological system that significantly reduces petroleum hydrocarbons in soil or water. The system uses either naturally occurring or supplied bacteria, System E.T nutrients, and a unique activation process custom-tailored to soil chemistry, contaminant volume, oil types, and oil . The industry had developed a colour coded standard to help users identify what sorbent to use at a moment’s notice to respond to a spill. Oil Only – White or light blue in colour and absorbs oil based fluids while repelling water. Best used outdoors; Universal – Grey in colour and absorbs both water and oil .
Oil spills impose serious damage to the environment. A spilled crude oil or its products affect aquatic flora and fauna and influence the atmosphere as well. Such pollutants are especially dangerous for the water ecosystems, where biological self-purification processes are slower (for example the Baltic Sea), than in warmer regions. In this paper, we evaluate a sorption capacity of. A number of natural sorbents have been studied for use in oil-spill cleanup, e.g. cotton (Johnson et al., ; Choi and Kwon ; Choi, ), wool (Radetic et al., ) and bark (Haussard et al., ) which can be excellent oil sorbent because of its hydrophobic and oliophilic character.
lecithin in the lab to keep oil slicks from reforming (Figure 1). Soy lecithin-surfactant mixtures produce smaller and more stable oil droplets than Corexit A to provide microbes with a steady meal of oil. Sorbents also can be crafted from everyday materials. Using plastic for oil spill clean-up combines old and new. Oil sorbents comprise a wide range of organic, inorganic, and synthetic products designed to recover oil in preference to water. Their composition and structure depend on the material used and the intended application in the response (ITOPF, ).Sorbents bind oil via absorption, adsorption, or a combination of both mechanisms, without the formation or breakage of chemical bonds.

Selection criteria and laboratory evaluation of oil spill sorbents: update II. [L Anna Robertson; Canada. Environmental Conservation Directorate.] -- A four part standard sorbent laboratory test procedure was developed to evaluate a number of sorbents.
The sorbents were tested using three different petroleum products, which were aged for periods. Additional Physical Format: Online version: Neaves, W.M.

Most synthetic sorbents can absorb up 70 times their own weight in oil. The characteristics of both sorbents and oil types must be considered when choosing sorbents for cleaning up oil spills: Rate of absorption — The absorption of oil is faster with lighter oil products.
Once absorbed the oil cannot be re. The use of consensus-based standards to improve oil spill equipment and selection protocols, Proc.

Updates to this publication were release every four or five years. The time lag between publications and the limited number of sorbents tested were acceptable limitations to this program as interest in sorbents was relatively limited. Since that time. a sorbent to fulfil the required criteria, it should have a ƴc value below that of water and above that of oil.
The surface ension oft seawater is approximately 60–65 mN/m; the value for oil varies depending on the composition but is typically around 20 mN/m. Therefore, for example, PTFE with a ƴc. Oil spills are a global concern due to the environmental and economical impact.
Various commercial systems have been developed to control these spills, including the use of fibers as sorbents. However, most sorbents end up in landfills or in cineration after single use. These options either produce another source of pollution or increase the oil recovery cost.

Oil sorbents play a very important part in the remediation processes of oil spills. To enhance the oil‐sorption properties and simplify the oil‐recovery process, various advanced oil sorbents and oil‐collecting devices based on them have been proposed recently.
Here, we firstly discuss the design considerations for the fabrication of oil. The use of consensus-based standards to improve oil spill equipment and selection protocols entitled Selection Criteria and Laboratory Evaluation of Oil Spill Sorbents.
oil spill sorbents. In general, solutions for the selection of the preferred sorbent are a compromise between performance, cost and environmental factors. To select a sorbent for an oil spill application, such materials (objects) must be ranked on the basis of a range of performance criteria.
Disasters such as the oil spill in Mexico Gulf in remind us again the importance of oil-sorbents in spilled oil cleanup and environmental remediation (Kerr et al.,Aguilera et al., ). High oil sorption capacity, low water pickup, and excellent reusability are the most important criteria for selecting oil sorbent (Adebajo et al.

Adsorption is a rapid and cost effective process to minimize the environmental impacts of oil spills and cleanup these pollutants.

Several oil spill remediation technologies exist: • In situ burning • Dispersants • Skimmers • Sorbents • Solidifying agents The effectiveness of each technology depends on the timeframe in which it is used. There is an increasing awareness of the impact of spilled crude oil and its refined products on human health and environment.
