Section: claims

1. A process for destruction of organic contaminants in dredged material for the formulation of a beneficial end product wherein the process is sequentially set forth:(a) sorting out particles greater than ¼ inch in size;(b) diluting the remaining material with water;(c) separating out sand, gravel and non-contaminated organic matter;(d) adding a reductive agent to the remaining material;(e) separating out particles from the remaining material such that about 10% of the dredged material remains;(f) adding an oxidizing agent to the remaining material from step (e);(g) adjusting the dwell time and amount of oxidizing agent added on the basis of total organic carbon (TOC) and chemical oxygen demand (COD) to the remaining material;(h) separating out particles 60 microns or less from the remaining material;(i) adding a reducing agent to the remaining material;(j) adding an oxidizing agent to particles 60 microns or less in size in the remaining material;(k) adjusting the pH in the remaining material;(l) separating out particles 60 microns or less in size from the remaining material;(m) adding a reducing agent to the particles from step (l) and dewatering;(n) separating the remaining material into:(1) filtrate; and(2) filter cake,wherein said filtrate is recycled to the above process. 2. The method of claim 1 further comprising providing a source of contaminated sediment. 3. The process of claim 1 wherein a site survey is conducted to determine the types of contamination involved.
