1. Filtɛri min be kɛ ni ɲɛɛ ɲuman ye: sɔngɔ gwɛlɛ min be sɔrɔ sɔngɔ-ye filtration filtre .
Filtɛri min be baara kɛ ni filtɛri ye, o lo be baara kɛ ni filɛrifɛnw ye minw be kɛ ka caya, o min be jii saniya ka caya ni farikolo yɔrɔ dɔ ye ani a be se ka minɛ cogo min na. Suguya sifa minw ka ca, olu ye:
1). Quartz bɔgɔ: fɛnɲɛnamafagalanw hakɛ 0,5-1,2, asidi barikaman ni alkali fanga, sɔngɔ dɔgɔman, tuma caaman na, u be kɛ ka jii minni kɛ ka kɔn furakɛli ɲɛ ani ka nɔgɔ furakɛ (a filɛ ni “Industriel jii furakɛli fɛɛrɛ ye”).
2). Karibɔni min be baara kɛ: a tilanin lo sɔngɔri ni mugu la, ani a be se ka se 500-1500m2/g ma (data: Ameriki ka laminiko ɲɛnabɔbaga EPA), a be se ka fɛɛnw ni nɛgɛ girinmanw nɔrɔ ɲɔgɔn na, minw bɛnnin lo jii saniyalanw ma ani fiɲɛ saniya ma.
3). Antrasite: a ka ca (1,4{3}}1.6g/cm3), n’a farala ni kuwrtz bɔgɔ ye walisa ka filtration ka baarakɛcogo fisaya, min ka ca a la, a be kɛ ka filɛri kɛ ni filtɛri fila ye.
Filtɛri filtɛli ka nafa ye ko a ka nɔgɔ ka nɔgɔya ani a ka kan ka to ka yɛlɛma tuma bɛɛ, ni saan 3-5 ɲɔgɔn ye.
2. Fiber filtɛri minanw: filɛri ɲuman ani filɛri ɲuman sugandili .
Fiber filtɛri minanw dilanna ni fɛɛnw ye minw be se ka yɛlɛma ani u be ni filɛri ɲuman ye. Lasigiden sifaw ye:
1). Polipropilɛn fiyɛ: koroziyɔn-}resant, be se ka kɛ PP kɔri filtɛri fɛn ye, porozite bonya 1-10 μm, min be kɛ ka so kɔnɔ jii saniyalanw filɛ ka kɔn.
2). Glass fiyɛ: a ka funteni be se ka yɛlɛma ( a ka ca ni degere 280 ye wala a be bɛn ɲɔgɔn ma ), a ka ca a la, a be kɛ ka gaziw furakɛ, i n’a fɔ kuran ka yɔrɔw nɔgɔli.
3). Seramiki fiyɛ: ka fara fɛnɲɛnamafagalanw ni fiyɛw cogoyaw kan, fanga barikaman, min bɛnnin lo ni jifilen jilaman ye kemikali baara la.
Fiber filtɛri minanw ka nafa ka dɔgɔ, a ka nɔgɔ ka kari a janya- baara kɔfɛ, ani a ka kan ka yɛlɛma tuma o tuma.
3. filtɛri minw be se ka filɛ ani minw be bɔra: fɛɛrɛw be se ka kɛ cogo ɲuman na .
1). Filtɛri min be ni membrane ye:
{{0} Mikrofilitiri (0,1-10μm): banakisɛw bɔ ani fɛn minw be yɛlɛma, i n’a fɔ jii saniyalanw ka filtɛrɛ laban.
- Ultrafiltration membrane (0.01-0.1 μm): be se ka banakisɛw minɛ ani a be kɛ ka caya furakɛli la (a filɛ "Membrane Savigatɛri fɛɛrɛ lajɛ").
2). Porous ceramic filter media: High temperature resistant (>1000 degere ), nɔgɔ be se ka nɔgɔ, nka a sɔngɔ ka gwɛlɛ, a ka ca a la, a be kɛ ka gazi saniya kosɔbɛ nɛgɛko la.
3). Filtɛri kura min be ɲɔgɔn sɔrɔ: i n’a fɔ filtɛri yɛlɛmani filtɛri, adsorption se be caya ni siɲɛ 3 ni kɔ ye (“Nature Materials” 2022 sɛgɛsɛgɛri), nka a ma jago kɛ fɔlɔ.
4. I be se ka filtɛri ɲuman sugandi cogo di?
Sɛgɛsɛgɛli dafanin min basiginin be filtɛrɛ laɲiniw kan (i n’a fɔ turbidite bɔli, nɔgɔ, decolosation), jii cogoyaw (pH hakɛ, funteni) ani musakaw hakɛ. Misaliya la:
- "Saga min be baara kɛ ni bɔgɔ ye" faralen ɲɔgɔn kan, o be kɛ ka caya jii yiriw la;
- Jii min be sɔrɔ elekitoroniki baara la, o ka kan ka bɛn ni membrane filtre media ye;
{{0} Seramiki filtɛriw ka fisa ni yɔrɔ min be yɛlɛma yɛlɛma, o lo ka fisa ni gazi ye min be yɛlɛma yɛlɛma.
Siniɲɛsigi la, komi lamini latanga sariyaw be fisayara, a ka bon-} tewori ani a ka jan yɔrɔ min na, o bena kɛ ɲinini ni yiriwali ka sinsinyɔrɔ ye.
