Organoclays Trap Incalcitrant Metals and Organic Compounds in Sediments Simultaneously

From Biomin, Inc.

The capability of organoclays as components of permeable sediment barriers has been researched extensively over the past several years..
Organoclays have been used in permeable walls to block the movement of a
DNAPL plume from an abandoned wood treating site, and for sediment stabilization at an old MGP site (from a power and light company).

Laboratory column tests and batch tests with organoclays have revealed that a standard, non-polar organoclay fixates all heavy metals, including lead, zinc, nickel, chrome and cadmium, but also inorganic acqueous mercury. In terms of organic hydrocarbons, such diverse compounds as dioxin and nitro-benzenes, as well as PCP, PCB, PNHA and BTEX are trapped effectively.

Filtration equipment is used to filter, thicken or clarify a mixture of different elements.
Dewatering Equipment
Dewatering equipment uses force, including vacuum and centrifugal motion, to separate water from solids.
Oil and Water Separators
Oil and water separators (oil-water separators, oil water separators) are remediation devices that separate oil from water and/or wastewater. This product area includes both aboveground and underground systems for the containment and treatment of oil-contaminated water.
Oil Skimmers
Oil skimmers are remediation devices used to remove oil from the surface of water, solvents, cleaning solutions, and other fluids. There are two basic types of oil skimmers. One type is used to filter and remove oil, debris, and unwanted materials. The other type is used to recover or capture oil in a usable state.
