Historyofdevelopment
InancientChina,filtrationtechnologywasusedinproduction,andpapermadeofplantfiberswasalreadyavailablein200BC.In105AD,CaiLunimprovedthepapermakingmethod.Duringthepapermakingprocess,hedippedplantfiberpulpondensethinbamboocurtains.Thewaterisfilteredthroughthegapsofthebamboocurtain,andathinlayerofwetpaperpulpisleftonthesurfaceofthebamboocurtain,anditbecomespaperwhenitdries.
Theearliestfiltrationwasmostlygravityfiltration.Later,pressurefiltrationwasusedtoincreasethefiltrationspeed,andthenvacuumfiltrationappeared.Therotarydrumvacuumfilterinventedatthebeginningofthe20thcenturyrealizedthecontinuityofthefiltrationoperation.Sincethen,varioustypesofcontinuousfiltershaveappearedoneafteranother.Intermittentlyoperatedfilters(suchasplateandframefilterpresses,etc.)havebeendevelopedbecausetheycanrealizeautomatedoperation,andthefilteringareaisgettinglargerandlarger.Inordertoobtainfilterresiduewithlowmoisturecontent,mechanicallypressedfiltershavebeendeveloped.
