Latest Patents

Sivonen holds a patent for a method for the removal of metals from an aqueous solution using lime precipitation. This invention relates to a process where a precipitate of metal hydroxide and gypsum is formed, which settles well and is easy to filter. The method operates at a high pH value, allowing for the effective precipitation of metals from their aqueous solutions. The slurry is recirculated multiple times in the precipitation space, resulting in gypsum being precipitated as separate crystals rather than a solid layer. This method is particularly suitable for neutralizing aqueous solutions from the pickling of refined steel. It enables the removal of metals and fluoride from the water, contributing to cleaner water sources.
