Remediation
AWE Solutions

AWE technology has numerous environmental applications for various industries and waste streams in which the technology has been deployed including the removal and destruction of hydrocarbons from soils, sludge and sediments. The technology has also demonstrated remarkable separation capabilities with applications to waste minimization and resource recovery from a wide array of waste streams.

Miami International/Opa-Locka Airport Clean-Up Miami, Florida Project

Miami International Airport had generated a significant amount of soils contaminated with jet fuel. In 1997, the our technology after successful completing a 5,000 ton pilot project was awarded an additional 50,000 tons of contaminated soils in a full-scale processing plants for remediation.

The soil disposal criteria used by the Florida Department of Environmental Resources Management (DERM) established acceptable levels for a varieety of parameters, which are used to determine whether the soil can be utilized as clean fill, is restricted for use within a permitted solid wste landfill, or must be disposed in an incineration-based process. The clean fill criteria are summarized in Table 1.

Restoration of Oil Spill of Contaminated Beach Sand, San Juan Puerto Rico

In January 1994 the tank barge Morris J. Beman went aground and broke up near San Juan, Puerto Rico. Over 8000,000 gallons of #6 bunker oil, from a cargo of 1.2 million gallons, were spilled from the barge, contaminating the ocean floor and the beach sands immediately adjacent to the Hilton and Radisson hotels in San Juan. The sands and sediments were dredged and stored in the swimming pool of the Hilton Hotel, where they were then rehandled and processed with the Ionizer technology. Even when forced to substantially improvise unit process equipment the technology was able to greatly reduce the oil contamination in the sands, allowing them to be placed back on the beach, recover significant amounts of the spilled oil for recycling and produce a clean water for discharge. The levels of total recoverable petroleum hydrocarbons were reduced from an average of 6000 to less than 29 ppm a reduction of 99% using the Ionizer technology.
