Low density glassy materials for bioremediation supports

A bioremediation support for the support of microorganisms used in the biotreatment of an aqueous waste stream or contaminated vapor is made of a low-density siliceous glassy material. This material has a cellular or frothy texture, large pores of greater than 1,000 Anstrom units in diameter dispers...

Beschreibung
Zusammenfassung:	A bioremediation support for the support of microorganisms used in the biotreatment of an aqueous waste stream or contaminated vapor is made of a low-density siliceous glassy material. This material has a cellular or frothy texture, large pores of greater than 1,000 Anstrom units in diameter dispersed throughout the material, a high macropore volume in pores of greater than 1,000 ANGSTROM of more than 0.3 cc/cc and a BET surface area of greater than 10 m2/g. A preferred material is pumice.
