1. Methylene xiav:Feem ntau hais lus, qhov siab dua qhov methylene xiav tus nqi ntawm cov hmoov activated carbon, qhov zoo dua cov nyhuv decolorization.
2. Mesh loj:Feem ntau hais lus, qhov me me mesh loj ntawm hmoov activated carbon, qhov zoo dua cov nyhuv decolorization. Cov pa mesh loj yog li 200 meshes. Txawm li cas los xij, yog tias qhov mesh loj ntawm cov hmoov activated carbon ncav cuag 300 meshes, qhov decolorization ceev ntawm ib chav tsev yuav nce ntau. Txawm li cas los xij, vim tias cov pa roj carbon activated zoo dhau lawm, nws yuav ua rau muaj teeb meem defiltration hauv kev tsim khoom.
3. PH tus nqi:Feem ntau hais lus, hmoov activated carbon muaj qhov zoo tshaj plaws decolorization nyhuv nyob rau hauv acidic tej yam kev mob.
