Pochiza mpweya wotayira zinyalala, makamaka pochiza mpweya wotayira zinyalala wa mafakitale wokhala ndi ma VOC (monga kusindikiza, kujambula, ndi makampani opanga mankhwala), ufa wa dziko lapansi wa diatomaceous ukhoza kuyamwa zinthu zovulaza bwino. Kapangidwe ka ma porous a ufa wa diatomite kali ndi malo ambiri olandirira, omwe amatha kugwira mamolekyu a VOC kudzera mu mphamvu za van der Waals ndi mphamvu zamagetsi. Pambuyo posintha pamwamba pa ufa wa dziko lapansi wa diatomaceous (monga kuyika mpweya woyatsidwa, titanium dioxide, ndi zina zotero), mphamvu yake yolandirira ma VOC ikhoza kukonzedwanso. Potengera malo ojambulira utoto a fakitale yopanga magalimoto mwachitsanzo, mpweya wotayira umakhala ndi benzene, toluene, ndi xylene yambiri. Mpweya wotayira ukadutsa mu fyuluta yodzazidwa ndi ufa wosinthidwa wa dziko lapansi wa diatomaceous, kuchuluka kwa benzene, toluene, ndi xylene kumatha kufika pa 90%, ndipo kuchuluka kwa ma VOC mu mpweya wotayira wokonzedwa kumakhala kotsika kuposa muyezo wadziko lonse wotulutsa mpweya (≤80 mg/m³). Poyerekeza ndi njira yachikhalidwe yogwiritsira ntchito mpweya wopangidwa ndi activated carbon, ufa wa diatomaceous earth uli ndi ubwino wa mtengo wotsika, moyo wautali (nthawi yokwanira yogwiritsira ntchito mpweya wopangidwa ndi activated carbon ndi nthawi 2-3 kuposa mpweya wopangidwa ndi activated carbon), komanso kusinthika mosavuta (kungathe kubwezeretsedwanso mwa kutentha pa 300-400°C, ndipo mphamvu yogwiritsira ntchito mpweya wopangidwa ndi activated carbon ikhoza kubwezeretsedwa kufika pa 85% pambuyo pokonzanso).

Pochiza mpweya woipa (monga malo oyeretsera zinyalala, malo oyeretsera zinyalala, ndi mafamu a ziweto), ufa wa diatomaceous earth ungathandizenso kuchotsa fungo loipa. Zinthu zoipa zimaphatikizapo ammonia, hydrogen sulfide, ndi mercaptans. Kapangidwe ka ufa wa diatomite kamene kamalowa m'maselo amatha kuyamwa mamolekyu oipawa, ndipo magulu ogwira ntchito a alkaline kapena acidic pamwamba pake (atasinthidwa) amatha kuchitapo kanthu ndi zinthu zoipa kuti awonongeke kukhala zinthu zopanda vuto. Fakitale yoyeretsera zinyalala mumzinda wa m'mphepete mwa nyanja idagwiritsa ntchito njira yoyeretsera zinyalala yochokera ku ufa wa diatomaceous earth. Pambuyo poyika, kuchuluka kwa fungo lozungulira chomeracho kunachepetsedwa kuchoka pa 5000 OU/m³ kufika pa 200 OU/m³, zomwe zinali zochepa kwambiri kuposa muyezo wadziko lonse (≤400 OU/m³), ndipo madandaulo ochokera kwa okhala pafupi adachepetsedwa ndi 90%. Nthawi yomweyo, ufa wa diatomaceous earth womwe umagwiritsidwa ntchito mu dongosolo loyeretsera zinyalala ukhoza kugwiritsidwanso ntchito pambuyo pokonzanso, kuchepetsa kuchuluka kwa zinyalala zolimba zomwe zimapangidwa.​

Pochiza madzi otayidwa, ufa wa diatomaceous earth wothira madzi ambiri ungagwiritsidwe ntchito pochiza madzi otayidwa a mafakitale okhala ndi zinthu zoipitsa zachilengedwe (monga kusindikiza ndi kupaka utoto madzi otayidwa, madzi otayidwa a mankhwala). Kusindikiza ndi kupaka utoto madzi otayidwa kuli ndi utoto wambiri ndi zinthu zina zothandizira, zomwe zili ndi chroma ndi COD yambiri, ndipo zimakhala zovuta kuziwononga. Kuwonjezera ufa wa diatomaceous earth wa 2-5% ku madzi otayidwa kumatha kuyamwa utoto ndi zinthu zachilengedwe m'madzi. Mayeso akuwonetsa kuti kuchuluka kwa chroma komwe madzi otayidwa amachotsedwa kumatha kufika pa 95%, ndipo kuchuluka kwa COD kumatha kufika pa 60-80%. Poyerekeza ndi ma coagulants achikhalidwe (monga aluminium sulfate), ufa wa diatomaceous earth ulibe kuipitsidwa kwachiwiri (kulibe zotsalira za aluminium ion), ndipo matope omwe amapangidwa pambuyo pochiza ndi osavuta kuumitsa ndipo angagwiritsidwe ntchito ngati chowonjezera cha zomangamanga pambuyo pochiza popanda vuto. Fakitale yosindikizira ndi kupaka utoto ku Zhejiang idagwiritsa ntchito ufa wa diatomaceous earth pochiza madzi otayidwa. Pambuyo pokonza, madzi otayira amatha kubwezeretsedwanso kuti apange (pambuyo pokonza zinthu zina zapamwamba), kuchepetsa kugwiritsa ntchito madzi kwa fakitale ndi 30% ndikusunga ndalama zambiri zamadzi.

Ufa wathu wa diatomaceous earth womwe umayamwa kwambiri kuti uteteze chilengedwe uli ndi mitundu yosiyanasiyana ya zinthu, kuphatikizapo ufa, granular, ndi extruded. Ufa wa (100-800 mesh) ndi woyenera kuyeretsa madzi otayira ndi mipanda yoyamwa mpweya wotayira; ufa wa granular (1-5 mm) ndi woyenera kuyeretsa makina okhazikika poyeretsa mpweya wotayira; ufa wa extruded (5-10 mm) ndi woyenera kuyeretsa mpweya wotayira waukulu wokhala ndi mpweya wambiri. Zizindikiro zazikulu zaukadaulo za zinthu zathu ndi izi: malo enieni ≥200 m²/g, voliyumu ya pore ≥0.8 cm³/g, mphamvu ya adsorption ya methylene blue ≥15 mL/0.1g, ndi chinyezi ≤3%. Tikhozanso kupereka zinthu zopangidwa ndi ufa wa dziko lapansi wa diatomaceous modified malinga ndi zinthu zomwe makasitomala amakonzera, monga ufa wa diatomite wodzazidwa ndi kaboni (wa VOCs adsorption), ufa wa diatomite wodzazidwa ndi titanium dioxide (wowononga zinthu zodetsa zachilengedwe), ndi ufa wa alkaline diatomite (wa hydrogen sulfide adsorption).​

Mu njira yopangira, timagwiritsa ntchito ukadaulo wapamwamba woyambitsa kuti tiwonjezere mphamvu ya kulowetsedwa kwa ufa wa dziko lapansi wa diatomaceous. Njira yoyambitsa imaphatikizapo kuyambitsa asidi (pogwiritsa ntchito dilute sulfuric acid kuti idule pamwamba pa tinthu ta diatomite, kuwonjezera kuchuluka kwa ma pores) ndi kuyambitsa kutentha (kukonza kutentha kwambiri kuti tichotse zonyansa zachilengedwe m'ma pores ndikukulitsa kukula kwa ma pores). Ufa wa dziko lapansi wa diatomaceous womwe wayambitsidwa uli ndi malo enaake owonjezera ndi 30-50% poyerekeza ndi miyala yoyambirira, ndipo mphamvu ya kulowetsedwa imawonjezeka kwambiri. Gulu lililonse la zinthu lidzayesedwa mphamvu ya kulowetsedwa (pogwiritsa ntchito methylene blue solution ngati adsorbate) ndi kuyesa kapangidwe ka ma pores (pogwiritsa ntchito chowunikira chapadera cha malo ozungulira), kuonetsetsa kuti magwiridwe antchito azinthu akukwaniritsa zofunikira.​
