Title: Thomas E Higgins: Innovator in Environmental Remediation
Introduction
Thomas E Higgins is a notable inventor based in Reston, VA (US). He has made significant contributions to the field of environmental remediation, particularly in the treatment of chromium ore processing residues. With a total of 2 patents, Higgins has developed innovative methods that address contamination issues effectively.
Latest Patents
Higgins' latest patents include a method for the treatment of in-ground chromium ore processing residue. This method involves providing ferrous sulfide as a substantially insoluble material in the residue deposit. The ferrous sulfide remains in place within the soil or residue, acting continuously to chemically reduce and remove contamination. As hexavalent chromium diffuses from the soil, it is reduced by the ferrous sulfide, which can be introduced into the underground deposit through a specific injection process.
Another significant patent is the process for the in situ bioremediation of Cr(VI)-bearing solids. This process focuses on the biological reduction of Cr(VI) to insoluble Cr(III). The pH of the Cr(VI)-bearing solids is adjusted to a range of about 6.5 to 9.5 and mixed with organic material containing bacteria and nutrients to facilitate the reduction process.
