Application
  
A-AS-04 activated alumina is manufactured from aluminium hydroxide by dehydroxylating it in
a way that produces a highly porous material;

A-AS-DF activated alumina is also widely used to remove fluoride from drinking water.  Basically,
the more alumina in the filter, the less fluoride will be in the final, filtered water.

A-AS-MS is for absorbent H2O2

A-AS-AC is for chlorine absorbent

A-AS-C in hydrogen peroxide production, as a selective adsorbent for many chemicals including,in  removal from gas streams .

A-AS-A activated alumina is used as a charge material in foreline traps to prevent  generated by  from
backstreaming into the system

Industry standard HG/T39272007 Activated Alumina is issued by UNION ALKALIES & CHEMICALS GROUP LTD
