Tilmaamaha ugu muhiimsan
1. Aagga sifaynta weyn (5-10 jeer ka ah walxaha filter cylindrical caadiga ah)
2. Kala duwanaanta saxsanaanta sifaynta ballaaran: Saxnaanta sifaynta ee birta dhalaalka ah ee birta dhalaalaysa ayaa loo habeyn karaa iyadoo loo eegayo baahiyaha, saxnaanta sifeynta guud waa 1-100 microns.
3. Permeability: Qaab dhismeedka fiber-ka ee shaandhada dhalaalka ah ee birta ah ayaa ka dhigaysa in ay yeelato awood wanaagsan oo si wax ku ool ah u shaandhayso wasakhda adag ee dhalaalka.
4. Nolosha adeegga: Walxaha shaandhada dhalaalka birta ah waxay leedahay nolol adeeg oo dheer waxayna u adkeysan kartaa isticmaalka muddada dheer ee jawiga heerkulka sare iyo warbaahinta daxalka leh.
Hababka isku xirka ugu muhiimsan
1. Interface caadiga ah (sida 222, 220, 226)
2. Xidhiidhka interface furitaanka degdega ah
3. Isku xirka dunta
4. Isku xirka calanka
5. Jiid xidhiidhka usha
6. Interface gaar ah oo habaysan
Goobta Codsiga
Walxaha filtarrada dhalaalka ah ee birta ah ayaa si weyn loogu isticmaalaa goobaha sifaynta dhalaalidda heerkulka sare sida dhalaalidda birta, shubista, petrochemical, iwm.Walxaha filtarrada dhalaalka birta aan-dhalatay waxay ku habboon tahay shaandhaynta heer-kulka sare iyo walxaha wasakhaysan.Waxay leedahay faa'iidooyinka caabbinta heerkulka sare, caabbinta daxalka, saxnaanta shaandhaynta sare iyo nolosha adeegga dheer.Waxaa inta badan loo adeegsadaa goobaha sifaynta ee la xidhiidha biraha, warshadaha kiimikada, elektiroonigga iyo warshadaha kale.
