Skotan Zaklady Garbarskie, Poland: Tannery Effluent Tank Lining

A tannery in Poland was experiencing a problem with three concrete tanks used to contact process chemical waste products from their factory. Each tank, 80% of which was standing above ground level, was of vertical cylindrical design with funnel shaped floors sloping at 45°. Built from reinforced concrete some forty-five years ago, the tanks had been lined with acid-proof tiles.
