Abstract

A process for decontamination and separation of a contaminated fluid including a first agent, a second agent, and a third agent may include the steps of directing the contaminated fluid to a first tank, substantially separating first agent in a first layer, a second agent in a second layer and a third agent in a third layer in a first tank, generating a vacuum and removing the first agent and the second agent by the vacuum, placing the first agent and the second agent in a second tank, generating a vacuum and removing the first agent and the second agent by the vacuum and placing the first and second agents in a second tank, removing the third agent by a vacuum and placing the third agent in a third tank, separating the first agent and the second agent based upon the gravities of the first and second agents, removing the second agent from the second tank and placing the second agent in the first tank based upon and until the first agent is detected.
