I-diatomite filter aid ibamba ikakhulu amasuntswana okungcola okuqinileyo anqunyanyiswe kulwelo kumphezulu kunye nomjelo wesiphakathi ngokwenza le misebenzi mithathu ilandelayo, ukuze kuphunyezwe injongo yokwahlulwa kolwelo oluqinileyo:

1. Isiphumo seSieving Esi sisiphumo sokuhluza umphezulu. Xa i-fluid ihamba nge-diatomaceous earth, ii-pores ze-diatomaceous earth zincinci kune-particle ye-particle ye-particle ye-particle yokungcola, ngoko ke iinqununu zokungcola azikwazi ukudlula kwaye zithintelwe. Esi siphumo sibizwa ngokuba yi-screening effect. Ngapha koko, umphezulu wekhekhe lokucoca unokubonwa njengendawo yokuhluza kunye nobungakanani obulinganayo bepore. Xa ububanzi beengqungquthela eziqinileyo zingekho ngaphantsi (okanye ngaphantsi ngaphantsi) ububanzi beepores ze-diatomite, iinqununu eziqinileyo ziya "kuhluzwa ekumisweni". Yahlula ngaphandle, dlala indima yokucoca umphezulu.

2. Isiphumo esinzulu Isiphumo sobunzulu sisiphumo sokugcinwa kokucoca okunzulu. Kwi-filtration enzulu, inkqubo yokwahlula ivela kuphela "ngaphakathi" kwi-medium. Inxalenye amasuntswana ukungcola encinane ngokwentelekiso ukungena kumphezulu ikhekhe lokucoca zivaliwe imijelo microporous tortuous ngaphakathi emhlabeni diatomaceous kunye nemingxuma encinane ngaphakathi ikhekhe lokucoca. Olu hlobo lwamaqhekeza luhlala luncinci kune-micropores yomhlaba we-diatomaceous. Xa amasuntswana abetha udonga lomjelo, anokushiya ukuhamba kolwelo. Nangona kunjalo, ingaba inokufikelela kweli nqanaba kuxhomekeke kumandla angenayo kunye nokuchasana kwamasuntswana. Ibhalansi, olu hlobo lokungenelela kunye nokuhlola ziyafana kwindalo, zombini ziyinxalenye yesenzo soomatshini. Ukukwazi ukuhluza amasuntswana aqinileyo ngokusisiseko kunxulumene kuphela nobungakanani obunxulumene kunye nokumila kwamasuntswana aqinileyo kunye neepores.

3. I-Adsorption I-adsorption yahluke ngokupheleleyo kwezi ndlela zimbini zokuhluza. Enyanisweni, esi siphumo sinokuthi sithathwe njengento ekhangayo ye-electrokinetic, exhomekeke ngokukodwa kwiipropati zomphezulu wamasuntswana aqinileyo kunye nomhlaba we-diatomaceous ngokwawo. Xa loo masuntswana anemingxuma emincinci kumhlaba we-diatomaceous engqubana kumphezulu ongaphakathi we-diatomaceous earth, atsalwa ziintlawulo ezichaseneyo. Kukwakho uhlobo lomtsalane phakathi kwamasuntswana ukwenza amaqela kwaye abambelele kumhlaba wediatomaceous. Zombini zeze-adsorption, kwaye i-adsorption inzima kakhulu kunezo zimbini zangaphambili. Ngokuqhelekileyo kukholelwa ukuba isizathu sokuba i-particles eqinile encinci kune-diameter ye-pore ibanjwe ngokuyinhloko ngenxa: (1) I-Intermolecular forces (ebizwa ngokuba yi-van der Waals attraction), kubandakanywa i-dipoles Effect, i-dipole effect i-induced dipole kunye ne-instant dipole effect; (2) ubukho beZeta ezinokubakho; (3) inkqubo yokutshintsha i-ion

Ukusuka kule misebenzi mithathu ingasentla, kwinkqubo yokuhluza uxinzelelo lomnatha wokunqunyanyiswa, i-diatomite ekhululekileyo yokucoca i-granular isetyenziswa njengendlela yokucoca, eyona nto ibonelela ngeepores ezininzi kangangoko kunokwenzeka kumaleko okucoca okuphakathi, ikeyiki yokucoca, kunye nokwenza Umaleko we-spacer we pores uvumela ukunqunyanyiswa ukuba kudlule kwiipores ezincinci zomaleko wesithintelo, kunye neqhekeza leengcongolo kumphezulu wolwelo kunye nokurhintyela kumphezulu wolwelo. medium, ukuze okuqinileyo kunye nolwelo bahlulwe.
