Sinadari microstructure na volcanic dutse biofilter abu ne kamar haka

1. Ƙwararrun sinadarai na ƙwayoyin cuta: dutsen dutsen biofilter abu ne mai jurewa, rashin aiki, kuma baya shiga cikin halayen biochemical na biofilm a cikin yanayi.

2. Surface wutar lantarki da hydrophilicity: saman dutsen dutse biofilter yana da tabbataccen cajin, wanda yake da kyau ga ci gaban ƙananan ƙwayoyin cuta.Yana da karfi hydrophilicity, babban adadin haɗe biofilm da sauri sauri.
