Latest Patents

Devender K Jain holds a patent for a groundbreaking invention titled "Bacterial leaching process and composition." This patent describes a method for effectively removing heavy metals and significantly reducing indicator bacteria present in municipal sludges. The process involves lowering the pH of the sludge from about 7 to 8 to approximately 2.0 to 2.5 by adding a 10% by volume inoculum containing a mixture of microorganisms, including Thiobacillus thiooxidans ATCC 55127 and Thiobacillus thioparus ATCC 55128, along with 1 to 3 grams per liter of sulfur. The incubation period lasts at least 40 hours, during which the heavy metals are solubilized, and the concentration of indicator bacteria is reduced to a non-toxic level. The final step involves recovering the metals from the low pH treated sludge.
