Lub ntsiab yam tseem ceeb cuam tshuam rau kev ua haujlwm adsorption ntawm activated alumina desiccant yog:
⑴ particle loj: qhov me me ntawm qhov me me, qhov siab dua qhov muaj peev xwm adsorption, tab sis qhov me me ntawm qhov me me, qhov qis dua particle zog, uas cuam tshuam rau nws lub neej kev pab cuam.
⑵ pH tus nqi dej nyoos: thaum tus nqi pH ntau dua 5, qhov qis pH tus nqi, qhov siab dua qhov muaj peev xwm adsorption ntawm activated alumina. ⑶ thawj zaug fluorine concentration ntawm cov dej nyoos: qhov siab dua qhov pib fluorine concentration, qhov loj dua lub peev xwm adsorption.
(3) alkalinity ntawm cov dej nyoos: qhov concentration ntawm bicarbonate nyob rau hauv cov dej nyoos yog siab, thiab lub peev xwm adsorption yuav raug txo.
(4) chloride ion thiab sulfate ion. (5) Cov nyhuv ntawm arsenic: activated alumina tuaj yeem adsorb arsenic hauv dej. Kev sib sau ntawm arsenic ntawm activated alumina yuav txo tau lub peev xwm adsorption ntawm fluorine ions, thiab nws yog ib qho nyuaj rau elute arsenic ions thaum lub sij hawm regeneration.
