Latest Patents

David J Heiser holds a patent for an "Aqueous Ferrous Waste Conversion Process." This process involves converting an aqueous ferrous sulfate waste stream into sludge and improved water effluent. The method utilizes a flow process that operates at ambient indoor temperature and pressure. It includes the turbulent mixing of the waste stream with a substantial excess of gaseous oxygen and a small excess of impalpable calcium carbonate. The resulting sludge is classified into a coarser solids fraction and an aqueous suspension of finer solids. Additionally, the process addresses the presence of free sulfuric acid by precipitating a primary gypsum product through neutralization before the sludging operation.
