Abstract

In the NW area of RomaniaÂ ( Salaj )Â are approved technologies prepare the volcanic tuffÂ ( zeolites )Â to Mirșid for
use in: waste water treatment, animal feed, improving soil pH. In this area there have been researches on determining possible use of volcanic tuff that load on biofilters for wastewater treatment.In this context were prepared tuff aprons Ã¸: 30-40 mm, 40 - 60 mm, 60 - 120 mm and 120-240 mm with Ï = 2.4gcmc, an apparent Ï = 1.6g/cmc, a breaking strength by clearing > 360 daN/cp, a shock resistance > 17 daN/ cp and a bulk Ï = 0.7 T/m.
