Title:
PERMEABLE POROUS COMPOSITE
Document Type and Number:
WIPO Patent Application WO/2011/015601
Kind Code:
A3
Abstract:
The present invention relates to a porous and permeable composite for treatment of contaminated fluids characterized in that said composite comprises a body of iron particles and 0.01-10% by weight of at least one functional ingredient distributed and locked in the pores and cavities of the iron body. The present invention also relates to methods of making a permeable porous composite for water treatment. The present invention also relates to use of a permeable porous composite according to any preceding claims for reducing the content of contaminants in a fluid, wherein said fluid is allowed to pass through the permeable composite.
