1. Natural ka fɛɛnw filɛcogo .
1). Quartz bɔgɔ
- Fɛɛnba ye silikoni diwɔsidi (SiO2) ye, min ka gɛlɛya ka bon (Mohs 7) ani kemikali basigili barikaman. A be kɛ ka caya jii furakɛli filɛri yɔrɔw la.
- Hakilina minw ka ca: 0,5-1,2mm (filtration coarse), 0,3-0,5mm (filtration ɲuman), i ka "Kɔgɔ furakɛli kunnafoni di" (CJ/T 43-2005).
- Nafaw: a ka ca (2,65g/cm3), a kɔfɛko caman.
2). An5rasi
- Porosite ka bon ni 50%-60% ye, a be se ka yɛlɛma ni fanga ye, ani a ka ca a la, a be baara kɛ ni quartz bɔgɔ ye ka filɛrikɛlan fila dilan.
- Particle bonya hakɛ: 0,8-1,8mm, densitɛri 1,4-1,6g/cm3 (a ka nɔgɔ ka tɛmɛ kuardz bɔgɔ kan, o be se ka kɔfɛla fanga dɔgɔya).
3). Zolikacɛ
- Natural iyɔn yɛlɛmafɛn, ni amoniyaki ni nɛgɛ girinmanw kan, a be se ka kɛ jii nɔgɔw furakɛli la.
2. Polimeri minanw filtɛriw ka filtɛri .
1). Polipropilɛn (PP) fiyɛ
- Asidi ni alkali min be se ka yɛlɛma (pH 1{{2}14), banakisɛw kɛlɛ, u be dilan ka kɛ filɛrifɛnw ye wala ka filɛrifɛnw kɛ, minw be kɛ kemikali ni dumuniko la.
- Filɛri tiɲɛtigiya: 1-100 μm (a yɛlɛmana ka kɛɲɛ ni fani dilan hakɛ ye).
2). Poliyesitɛri (PET) min tɛ - fani ye
- Fanga ɲuman ni fiɲɛ ɲuman, min ka ca fiɲɛ filtration kɔnɔ (i n’a fɔ HEPA filtɛri).
3). Poliyetilɛn (PE) filtɛri min be ni sinema ye .
- Mikroporozi sigicogo min dilanna ni -tempitiri ye, ni 0,1μm ye, min be kɛ ka jii labɛn.
3. Nɛgɛ ni ceramiki filtɛri media .
1). Nɛgɛ juru min tɛ se ka yɛlɛma .
- Model 304/316L, funteni min be se ka yɛlɛma ( Less ka tɛmɛ degere 800 kan), porozite bonya be se 20-200 mesh ma, min be kɛ ka petɔrɔli ni furakisɛw dilan.
2). Seramiki fanga
- Made of alumina or silicon carbide, with a compressive strength of >10MPa, min ka kan ni -tempitiri gazi buguri bɔli ye (i n’a fɔ nɔgɔ incineration yiriw).
4. Fɛɛn kɛrɛnkɛrɛnninw
1). karbɔni min be baara kɛ
- yɔrɔ kɛrɛnkɛrɛnnin 500-1500m2/g (a filɛ "Koal Granulated Carbon Standard" GB/T 7701.1-2008), o be se ka kɛ sababu ye ka fɛɛnw ni kɔlɔri tɔw dɛmɛ.
2). filtɛri min be kɛ ni filtɛri ye .
- The surface is loaded with Fe₃O₄, and the metal particles in oily wastewater are quickly separated by magnetic field, with a recovery rate of >90%.
Ladili dɔw:
- Finsiyɔn filtɛri (i n’a fɔ "karbɔni + karbɔni") be se ka jateminɛ kɛ farikolo ka filtɛrɛ ni kemikalifɛnw bɔli fila bɛɛ la;
- Fɛɛn minw be bɔ i n’a fɔ grafɛn filtɛri membrane (filtration 0,001 μm) olu bele be laboratuwari la ani u sɔngɔ ka gwɛlɛ dɔɔni.
