ABSTRACT:
A method and apparatus for removal of contaminants from fluid columns utilizes a solidifying polymer-based filtration media to extract pollutants, such as organic compounds and metals. Dissolved, emulsified or suspended contaminants are absorbed and solidified into an easily retrievable mass and retained within a replaceable filter container. Solidified contaminants may not leach when exposed to pressure limits currently used to determine landfill acceptability, may be incinerated as fuel for their BTU content or used as a component in the production of asphalt, roofing material or other tar-like compounds. Treated fluid columns exit the process containing acceptable levels of contaminants to permit free release into the environment.
