DEVELOPMENT OF LOW-COST ACTIVATED CARBON FOR REMOVAL OF VOCS AND PHARMACEUTICALS FROM RESIDENTIAL DRINKING WATER

The present invention relates to systems incorporating, and uses of, hydrothermally dehydrated carbonaceous products, particularly from waste sources, that when activated provide for effective filters in water streams. The activated particles have high microporosity and provide an improved and affor...

Beschreibung
Zusammenfassung:	The present invention relates to systems incorporating, and uses of, hydrothermally dehydrated carbonaceous products, particularly from waste sources, that when activated provide for effective filters in water streams. The activated particles have high microporosity and provide an improved and affordable approach to decontamination of water sources. The invention further includes preparation of such systems, including steps of hydrothermal dehydration, optional carbonization, and physical activation.
