Willer Pos's Problem Solving Skills:
Developmente of chemical routes for metal extraction in stranded ores and wastes.
Treatment of effluents from landfill and waste treatment plants
Production of metal powder from metal residue and secondary source metals (e-waste, urban mining)
In deepth knowledge for water treatment using different chemical and physical technology (ozone, UV, Advanced oxidation technol
Willer Pos's Problem Solving Experience:
I developed a process for treatment of landfill leachate. It bring a brown colour efluente with high organic and metal load into a clear, transparent water for reuse.
I developed a process to convert lead salts (sulfate carbonate or chloride) into lead metal in a powder form. This hydrochemical route is much more efficient and environmentally sound than the pirometalurgical process. The end product is a lead powder with 99% purity.
I developed a metallurgical route to convert copper sulfide into copper sulfate, without the SO2 emission phase. The end product is copper sulfate or copper chloride.
